+=head1 NAME
+
+SSL_CIPHER_get_name, SSL_CIPHER_get_bits, SSL_CIPHER_get_version, SSL_CIPHER_description - get SSL_CIPHER properties
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ const char *SSL_CIPHER_get_name(const SSL_CIPHER *cipher);
+ int SSL_CIPHER_get_bits(const SSL_CIPHER *cipher, int *alg_bits);
+ char *SSL_CIPHER_get_version(const SSL_CIPHER *cipher);
+ char *SSL_CIPHER_description(const SSL_CIPHER *cipher, char *buf, int size);
+
+=head1 DESCRIPTION
+
+SSL_CIPHER_get_name() returns a pointer to the name of B<cipher>. If the
+argument is the NULL pointer, a pointer to the constant value "NONE" is
+returned.
+
+SSL_CIPHER_get_bits() returns the number of secret bits used for B<cipher>. If
+B<alg_bits> is not NULL, it contains the number of bits processed by the
+chosen algorithm. If B<cipher> is NULL, 0 is returned.
+
+SSL_CIPHER_get_version() returns string which indicates the SSL/TLS protocol
+version that first defined the cipher.
+This is currently B<SSLv2> or B<TLSv1/SSLv3>.
+In some cases it should possibly return "TLSv1.2" but does not;
+use SSL_CIPHER_description() instead.
+If B<cipher> is NULL, "(NONE)" is returned.
+
+SSL_CIPHER_description() returns a textual description of the cipher used
+into the buffer B<buf> of length B<len> provided. B<len> must be at least
+128 bytes, otherwise a pointer to the string "Buffer too small" is
+returned. If B<buf> is NULL, a buffer of 128 bytes is allocated using
+OPENSSL_malloc(). If the allocation fails, a pointer to the string
+"OPENSSL_malloc Error" is returned.
+
+=head1 NOTES
+
+The number of bits processed can be different from the secret bits. An
+export cipher like e.g. EXP-RC4-MD5 has only 40 secret bits. The algorithm
+does use the full 128 bits (which would be returned for B<alg_bits>), of
+which however 88bits are fixed. The search space is hence only 40 bits.
+
+The string returned by SSL_CIPHER_description() in case of success consists
+of cleartext information separated by one or more blanks in the following
+sequence:
+
+=over 4
+
+=item <ciphername>
+
+Textual representation of the cipher name.
+
+=item <protocol version>
+
+Protocol version: B<SSLv2>, B<SSLv3>, B<TLSv1.2>. The TLSv1.0 ciphers are
+flagged with SSLv3. No new ciphers were added by TLSv1.1.
+
+=item Kx=<key exchange>
+
+Key exchange method: B<RSA> (for export ciphers as B<RSA(512)> or
+B<RSA(1024)>), B<DH> (for export ciphers as B<DH(512)> or B<DH(1024)>),
+B<DH/RSA>, B<DH/DSS>, B<Fortezza>.
+
+=item Au=<authentication>
+
+Authentication method: B<RSA>, B<DSS>, B<DH>, B<None>. None is the
+representation of anonymous ciphers.
+
+=item Enc=<symmetric encryption method>
+
+Encryption method with number of secret bits: B<DES(40)>, B<DES(56)>,
+B<3DES(168)>, B<RC4(40)>, B<RC4(56)>, B<RC4(64)>, B<RC4(128)>,
+B<RC2(40)>, B<RC2(56)>, B<RC2(128)>, B<IDEA(128)>, B<Fortezza>, B<None>.
+
+=item Mac=<message authentication code>
+
+Message digest: B<MD5>, B<SHA1>.
+
+=item <export flag>
+
+If the cipher is flagged exportable with respect to old US crypto
+regulations, the word "B<export>" is printed.
+
+=back
+
+=head1 EXAMPLES
+
+Some examples for the output of SSL_CIPHER_description():
+
+ EDH-RSA-DES-CBC3-SHA    SSLv3 Kx=DH       Au=RSA  Enc=3DES(168) Mac=SHA1
+ EDH-DSS-DES-CBC3-SHA    SSLv3 Kx=DH       Au=DSS  Enc=3DES(168) Mac=SHA1
+ RC4-MD5                 SSLv3 Kx=RSA      Au=RSA  Enc=RC4(128)  Mac=MD5
+ EXP-RC4-MD5             SSLv3 Kx=RSA(512) Au=RSA  Enc=RC4(40)   Mac=MD5  export
+
+A comp[lete list can be retrieved by invoking the following command:
+
+ openssl ciphers -v ALL
+
+=head1 BUGS
+
+If SSL_CIPHER_description() is called with B<cipher> being NULL, the
+library crashes.
+
+If SSL_CIPHER_description() cannot handle a built-in cipher, the according
+description of the cipher property is B<unknown>. This case should not
+occur.
+
+The standard terminology for ephemeral Diffie-Hellman schemes is DHE
+(finite field) or ECDHE (elliptic curve).  This version of OpenSSL
+idiosyncratically reports these schemes as EDH and EECDH, even though
+it also accepts the standard terminology.
+
+It is recommended to use the standard terminology (DHE and ECDHE)
+during configuration (e.g. via SSL_CTX_set_cipher_list) for clarity of
+configuration.  OpenSSL versions after 1.0.2 will report the standard
+terms via SSL_CIPHER_get_name and SSL_CIPHER_description.

+=head1 NAME
+
+SSL_COMP_add_compression_method, SSL_COMP_free_compression_methods - handle SSL/TLS integrated compression methods
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ int SSL_COMP_add_compression_method(int id, COMP_METHOD *cm);
+
+ +void SSL_COMP_free_compression_methods(void);
+
+=head1 DESCRIPTION
+
+SSL_COMP_add_compression_method() adds the compression method B<cm> with
+the identifier B<id> to the list of available compression methods. This
+list is globally maintained for all SSL operations within this application.
+It cannot be set for specific SSL_CTX or SSL objects.
+
+SSL_COMP_free_compression_methods() frees the internal table of
+compression methods that were built internally, and possibly
+augmented by adding SSL_COMP_add_compression_method().
+
+=head1 NOTES
+
+The TLS standard (or SSLv3) allows the integration of compression methods
+into the communication. The TLS RFC does however not specify compression
+methods or their corresponding identifiers, so there is currently no compatible
+way to integrate compression with unknown peers. It is therefore currently not
+recommended to integrate compression into applications. Applications for
+non-public use may agree on certain compression methods. Using different
+compression methods with the same identifier will lead to connection failure.
+
+An OpenSSL client speaking a protocol that allows compression (SSLv3, TLSv1)
+will unconditionally send the list of all compression methods enabled with
+SSL_COMP_add_compression_method() to the server during the handshake.
+Unlike the mechanisms to set a cipher list, there is no method available to
+restrict the list of compression method on a per connection basis.
+
+An OpenSSL server will match the identifiers listed by a client against
+its own compression methods and will unconditionally activate compression
+when a matching identifier is found. There is no way to restrict the list
+of compression methods supported on a per connection basis.
+
+If enabled during compilation, the OpenSSL library will have the
+COMP_zlib() compression method available.
+
+=head1 WARNINGS
+
+Once the identities of the compression methods for the TLS protocol have
+been standardized, the compression API will most likely be changed. Using
+it in the current state is not recommended.
+
+=head1 RETURN VALUES
+
+SSL_COMP_add_compression_method() may return the following values:

+
+=head1 NOTES
+
+Command prefixes alter the commands recognised by subsequent SSL_CTX_cmd()

+such as "SSLProtocol", "SSLOptions" etc. are recognised instead of "Protocol"
+and "Options". Similarly for command lines if the prefix is "--ssl-" then 
+"--ssl-no_tls1_2" is recognised instead of "-no_tls1_2".
+
+If the B<SSL_CONF_FLAG_CMDLINE> flag is set then prefix checks are case
+sensitive and "-" is the default. In the unlikely even an application
+explicitly wants to set no prefix it must be explicitly set to "".
+
+If the B<SSL_CONF_FLAG_FILE> flag is set then prefix checks are case
+insensitive and no prefix is the default.

+
+=head1 DESCRIPTION
+
+The function SSL_CONF_cmd() performs configuration operation B<cmd> with
+optional parameter B<value> on B<ctx>. Its purpose is to simplify application
+configuration of B<SSL_CTX> or B<SSL> structures by providing a common
+framework for command line options or configuration files.
+
+SSL_CONF_cmd_value_type() returns the type of value that B<cmd> refers to.
+
+The function SSL_CONF_finish() must be called after all configuration
+operations have been completed. It is used to finalise any operations
+or to process defaults.
+
+=head1 SUPPORTED COMMAND LINE COMMANDS
+
+Currently supported B<cmd> names for command lines (i.e. when the
+flag B<SSL_CONF_CMDLINE> is set) are listed below. Note: all B<cmd> names
+are case sensitive. Unless otherwise stated commands can be used by
+both clients and servers and the B<value> parameter is not used. The default
+prefix for command line commands is B<-> and that is reflected below.
+
+=over 4
+
+=item B<-sigalgs>
+
+This sets the supported signature algorithms for TLS v1.2. For clients this
+value is used directly for the supported signature algorithms extension. For
+servers it is used to determine which signature algorithms to support.
+
+The B<value> argument should be a colon separated list of signature algorithms
+in order of decreasing preference of the form B<algorithm+hash>. B<algorithm>
+is one of B<RSA>, B<DSA> or B<ECDSA> and B<hash> is a supported algorithm
+OID short name such as B<SHA1>, B<SHA224>, B<SHA256>, B<SHA384> of B<SHA512>.
+Note: algorithm and hash names are case sensitive.
+
+If this option is not set then all signature algorithms supported by the
+OpenSSL library are permissible.
+
+=item B<-client_sigalgs>
+
+This sets the supported signature algorithms associated with client
+authentication for TLS v1.2. For servers the value is used in the supported
+signature algorithms field of a certificate request. For clients it is
+used to determine which signature algorithm to with the client certificate.
+If a server does not request a certificate this option has no effect.
+
+The syntax of B<value> is identical to B<-sigalgs>. If not set then
+the value set for B<-sigalgs> will be used instead.
+
+=item B<-curves>
+
+This sets the supported elliptic curves. For clients the curves are
+sent using the supported curves extension. For servers it is used
+to determine which curve to use. This setting affects curves used for both
+signatures and key exchange, if applicable.
+
+The B<value> argument is a colon separated list of curves. The curve can be
+either the B<NIST> name (e.g. B<P-256>) or an OpenSSL OID name (e.g
+B<prime256v1>). Curve names are case sensitive.
+
+=item B<-named_curve>
+
+This sets the temporary curve used for ephemeral ECDH modes. Only used by
+servers
+
+The B<value> argument is a curve name or the special value B<auto> which
+picks an appropriate curve based on client and server preferences. The curve
+can be either the B<NIST> name (e.g. B<P-256>) or an OpenSSL OID name
+(e.g B<prime256v1>). Curve names are case sensitive.

+
+Attempts to use the file B<value> in the "serverinfo" extension using the
+function SSL_CTX_use_serverinfo_file.
+
+=item B<DHParameters>
+
+Attempts to use the file B<value> as the set of temporary DH parameters for
+the appropriate context. This option is only supported if certificate
+operations are permitted.
+
+=item B<SignatureAlgorithms>
+
+This sets the supported signature algorithms for TLS v1.2. For clients this
+value is used directly for the supported signature algorithms extension. For
+servers it is used to determine which signature algorithms to support.
+
+The B<value> argument should be a colon separated list of signature algorithms
+in order of decreasing preference of the form B<algorithm+hash>. B<algorithm>
+is one of B<RSA>, B<DSA> or B<ECDSA> and B<hash> is a supported algorithm
+OID short name such as B<SHA1>, B<SHA224>, B<SHA256>, B<SHA384> of B<SHA512>.
+Note: algorithm and hash names are case sensitive.
+
+If this option is not set then all signature algorithms supported by the
+OpenSSL library are permissible.
+
+=item B<ClientSignatureAlgorithms>
+
+This sets the supported signature algorithms associated with client
+authentication for TLS v1.2. For servers the value is used in the supported
+signature algorithms field of a certificate request. For clients it is
+used to determine which signature algorithm to with the client certificate.
+
+The syntax of B<value> is identical to B<SignatureAlgorithms>. If not set then
+the value set for B<SignatureAlgorithms> will be used instead.
+
+=item B<Curves>
+
+This sets the supported elliptic curves. For clients the curves are
+sent using the supported curves extension. For servers it is used
+to determine which curve to use. This setting affects curves used for both
+signatures and key exchange, if applicable.
+
+The B<value> argument is a colon separated list of curves. The curve can be
+either the B<NIST> name (e.g. B<P-256>) or an OpenSSL OID name (e.g
+B<prime256v1>). Curve names are case sensitive.
+
+=item B<ECDHParameters>
+
+This sets the temporary curve used for ephemeral ECDH modes. Only used by
+servers
+
+The B<value> argument is a curve name or the special value B<Automatic> which
+picks an appropriate curve based on client and server preferences. The curve
+can be either the B<NIST> name (e.g. B<P-256>) or an OpenSSL OID name
+(e.g B<prime256v1>). Curve names are case sensitive.
+
+=item B<Protocol>
+
+The supported versions of the SSL or TLS protocol.
+
+The B<value> argument is a comma separated list of supported protocols to
+enable or disable. If an protocol is preceded by B<-> that version is disabled.
+Currently supported protocol values are B<SSLv2>, B<SSLv3>, B<TLSv1>,
+B<TLSv1.1> and B<TLSv1.2>.
+All protocol versions other than B<SSLv2> are enabled by default.
+To avoid inadvertent enabling of B<SSLv2>, when SSLv2 is disabled, it is not
+possible to enable it via the B<Protocol> command.
+
+=item B<Options>
+
+The B<value> argument is a comma separated list of various flags to set.
+If a flag string is preceded B<-> it is disabled. See the
+B<SSL_CTX_set_options> function for more details of individual options.
+
+Each option is listed below. Where an operation is enabled by default
+the B<-flag> syntax is needed to disable it.
+
+B<SessionTicket>: session ticket support, enabled by default. Inverse of
+B<SSL_OP_NO_TICKET>: that is B<-SessionTicket> is the same as setting
+B<SSL_OP_NO_TICKET>.
+
+B<Compression>: SSL/TLS compression support, enabled by default. Inverse
+of B<SSL_OP_NO_COMPRESSION>.
+
+B<EmptyFragments>: use empty fragments as a countermeasure against a
+SSL 3.0/TLS 1.0 protocol vulnerability affecting CBC ciphers. It
+is set by default. Inverse of B<SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS>.
+
+B<Bugs>: enable various bug workarounds. Same as B<SSL_OP_ALL>.
+
+B<DHSingle>: enable single use DH keys, set by default. Inverse of
+B<SSL_OP_DH_SINGLE>. Only used by servers.
+
+B<ECDHSingle> enable single use ECDH keys, set by default. Inverse of
+B<SSL_OP_ECDH_SINGLE>. Only used by servers.
+
+B<ServerPreference> use server and not client preference order when
+determining which cipher suite, signature algorithm or elliptic curve
+to use for an incoming connection.  Equivalent to
+B<SSL_OP_CIPHER_SERVER_PREFERENCE>. Only used by servers.
+
+B<NoResumptionOnRenegotiation> set
+B<SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION> flag. Only used by servers.
+
+B<UnsafeLegacyRenegotiation> permits the use of unsafe legacy renegotiation.
+Equivalent to B<SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION>.
+
+B<UnsafeLegacyServerConnect> permits the use of unsafe legacy renegotiation
+for OpenSSL clients only. Equivalent to B<SSL_OP_LEGACY_SERVER_CONNECT>.
+Set by default.

+=head1 SUPPORTED COMMAND TYPES
+
+The function SSL_CONF_cmd_value_type() currently returns one of the following
+types:
+
+=over 4
+
+=item B<SSL_CONF_TYPE_UNKNOWN>
+
+The B<cmd> string is unrecognised, this return value can be use to flag
+syntax errors.
+
+=item B<SSL_CONF_TYPE_STRING>
+
+The value is a string without any specific structure.
+
+=item B<SSL_CONF_TYPE_FILE>
+
+The value is a file name.
+
+=item B<SSL_CONF_TYPE_DIR>
+
+The value is a directory name.
+
+=back
+
+=head1 NOTES
+
+The order of operations is significant. This can be used to set either defaults
+or values which cannot be overridden. For example if an application calls:
+
+ SSL_CONF_cmd(ctx, "Protocol", "-SSLv3");
+ SSL_CONF_cmd(ctx, userparam, uservalue);
+
+it will disable SSLv3 support by default but the user can override it. If
+however the call sequence is:
+
+ SSL_CONF_cmd(ctx, userparam, uservalue);
+ SSL_CONF_cmd(ctx, "Protocol", "-SSLv3");
+
+then SSLv3 is B<always> disabled and attempt to override this by the user are
+ignored.
+
+By checking the return code of SSL_CTX_cmd() it is possible to query if a
+given B<cmd> is recognised, this is useful is SSL_CTX_cmd() values are
+mixed with additional application specific operations.
+
+For example an application might call SSL_CTX_cmd() and if it returns
+-2 (unrecognised command) continue with processing of application specific
+commands.
+
+Applications can also use SSL_CTX_cmd() to process command lines though the
+utility function SSL_CTX_cmd_argv() is normally used instead. One way
+to do this is to set the prefix to an appropriate value using
+SSL_CONF_CTX_set1_prefix(), pass the current argument to B<cmd> and the
+following argument to B<value> (which may be NULL).
+
+In this case if the return value is positive then it is used to skip that
+number of arguments as they have been processed by SSL_CTX_cmd(). If -2 is
+returned then B<cmd> is not recognised and application specific arguments
+can be checked instead. If -3 is returned a required argument is missing
+and an error is indicated. If 0 is returned some other error occurred and
+this can be reported back to the user.
+
+The function SSL_CONF_cmd_value_type() can be used by applications to
+check for the existence of a command or to perform additional syntax
+checking or translation of the command value. For example if the return
+value is B<SSL_CONF_TYPE_FILE> an application could translate a relative
+pathname to an absolute pathname.
+
+=head1 EXAMPLES
+
+Set supported signature algorithms:
+
+ SSL_CONF_cmd(ctx, "SignatureAlgorithms", "ECDSA+SHA256:RSA+SHA256:DSA+SHA256");
+
+Enable all protocols except SSLv3 and SSLv2:
+
+ SSL_CONF_cmd(ctx, "Protocol", "ALL,-SSLv3,-SSLv2");
+
+Only enable TLSv1.2:
+
+ SSL_CONF_cmd(ctx, "Protocol", "-ALL,TLSv1.2");
+
+Disable TLS session tickets:
+
+ SSL_CONF_cmd(ctx, "Options", "-SessionTicket");
+
+Set supported curves to P-256, P-384:
+
+ SSL_CONF_cmd(ctx, "Curves", "P-256:P-384");
+
+Set automatic support for any elliptic curve for key exchange:
+
+ SSL_CONF_cmd(ctx, "ECDHParameters", "Automatic");
+
+=head1 RETURN VALUES
+
+SSL_CONF_cmd() returns 1 if the value of B<cmd> is recognised and B<value> is
+B<NOT> used and 2 if both B<cmd> and B<value> are used. In other words it
+returns the number of arguments processed. This is useful when processing
+command lines.
+
+A return value of -2 means B<cmd> is not recognised.
+
+A return value of -3 means B<cmd> is recognised and the command requires a
+value but B<value> is NULL.
+
+A return code of 0 indicates that both B<cmd> and B<value> are valid but an
+error occurred attempting to perform the operation: for example due to an
+error in the syntax of B<value> in this case the error queue may provide
+additional information.
+
+SSL_CONF_finish() returns 1 for success and 0 for failure.

+
+=head1 DESCRIPTION
+
+SSL_CTX_set0_chain() and SSL_CTX_set1_chain() set the certificate chain
+associated with the current certificate of B<ctx> to B<sk>.
+
+SSL_CTX_add0_chain_cert() and SSL_CTX_add1_chain_cert() append the single
+certificate B<x509> to the chain associated with the current certificate of
+B<ctx>.
+
+SSL_CTX_get0_chain_certs() retrieves the chain associated with the current
+certificate of B<ctx>.
+
+SSL_CTX_clear_chain_certs() clears any existing chain associated with the
+current certificate of B<ctx>.  (This is implemented by calling
+SSL_CTX_set0_chain() with B<sk> set to B<NULL>).
+
+SSL_CTX_build_cert_chain() builds the certificate chain for B<ctx> normally
+this uses the chain store or the verify store if the chain store is not set.
+If the function is successful the built chain will replace any existing chain.
+The B<flags> parameter can be set to B<SSL_BUILD_CHAIN_FLAG_UNTRUSTED> to use
+existing chain certificates as untrusted CAs, B<SSL_BUILD_CHAIN_FLAG_NO_ROOT>
+to omit the root CA from the built chain, B<SSL_BUILD_CHAIN_FLAG_CHECK> to
+use all existing chain certificates only to build the chain (effectively
+sanity checking and rearranging them if necessary), the flag
+B<SSL_BUILD_CHAIN_FLAG_IGNORE_ERROR> ignores any errors during verification:
+if flag B<SSL_BUILD_CHAIN_FLAG_CLEAR_ERROR> is also set verification errors
+are cleared from the error queue.
+
+Each of these functions operates on the I<current> end entity
+(i.e. server or client) certificate. This is the last certificate loaded or
+selected on the corresponding B<ctx> structure.
+
+SSL_CTX_select_current_cert() selects B<x509> as the current end entity
+certificate, but only if B<x509> has already been loaded into B<ctx> using a
+function such as SSL_CTX_use_certificate().
+
+SSL_set0_chain(), SSL_set1_chain(), SSL_add0_chain_cert(),
+SSL_add1_chain_cert(), SSL_get0_chain_certs(), SSL_clear_chain_certs(),
+SSL_build_cert_chain(), SSL_select_current_cert() and SSL_set_current_cert()
+are similar except they apply to SSL structure B<ssl>.
+
+SSL_CTX_set_current_cert() changes the current certificate to a value based
+on the B<op> argument. Currently B<op> can be B<SSL_CERT_SET_FIRST> to use
+the first valid certificate or B<SSL_CERT_SET_NEXT> to set the next valid
+certificate after the current certificate. These two operations can be
+used to iterate over all certificates in an B<SSL_CTX> structure.
+
+SSL_set_current_cert() also supports the option B<SSL_CERT_SET_SERVER>.
+If B<ssl> is a server and has sent a certificate to a connected client
+this option sets that certificate to the current certificate and returns 1.
+If the negotiated ciphersuite is anonymous (and thus no certificate will
+be sent) 2 is returned and the current certificate is unchanged. If B<ssl>
+is not a server or a certificate has not been sent 0 is returned and
+the current certificate is unchanged.
+
+All these functions are implemented as macros. Those containing a B<1>
+increment the reference count of the supplied certificate or chain so it must
+be freed at some point after the operation. Those containing a B<0> do
+not increment reference counts and the supplied certificate or chain
+B<MUST NOT> be freed after the operation.
+
+=head1 NOTES
+
+The chains associate with an SSL_CTX structure are copied to any SSL
+structures when SSL_new() is called. SSL structures will not be affected
+by any chains subsequently changed in the parent SSL_CTX.
+
+One chain can be set for each key type supported by a server. So, for example,
+an RSA and a DSA certificate can (and often will) have different chains.
+
+The functions SSL_CTX_build_cert_chain() and SSL_build_cert_chain() can
+be used to check application configuration and to ensure any necessary
+subordinate CAs are sent in the correct order. Misconfigured applications
+sending incorrect certificate chains often cause problems with peers.
+
+For example an application can add any set of certificates using
+SSL_CTX_use_certificate_chain_file() then call SSL_CTX_build_cert_chain()
+with the option B<SSL_BUILD_CHAIN_FLAG_CHECK> to check and reorder them.
+
+Applications can issue non fatal warnings when checking chains by setting
+the flag B<SSL_BUILD_CHAIN_FLAG_IGNORE_ERRORS> and checking the return
+value.
+
+Calling SSL_CTX_build_cert_chain() or SSL_build_cert_chain() is more
+efficient than the automatic chain building as it is only performed once.
+Automatic chain building is performed on each new session.
+
+If any certificates are added using these functions no certificates added
+using SSL_CTX_add_extra_chain_cert() will be used.
+
+=head1 RETURN VALUES
+
+SSL_set_current_cert() with B<SSL_CERT_SET_SERVER> return 1 for success, 2 if
+no server certificate is used because the ciphersuites is anonymous and 0
+for failure.
+
+SSL_CTX_build_cert_chain() and SSL_build_cert_chain() return 1 for success
+and 0 for failure. If the flag B<SSL_BUILD_CHAIN_FLAG_IGNORE_ERROR> and
+a verification error occurs then 2 is returned.

+All other functions return 1 for success and 0 for failure.

+
+=head1 DESCRIPTION
+
+SSL_CTX_add_extra_chain_cert() adds the certificate B<x509> to the extra chain
+certificates associated with B<ctx>. Several certificates can be added one
+after another.
+
+SSL_CTX_clear_extra_chain_certs() clears all extra chain certificates
+associated with B<ctx>.
+
+These functions are implemented as macros.
+
+=head1 NOTES
+
+When sending a certificate chain, extra chain certificates are sent in order
+following the end entity certificate.
+
+If no chain is specified, the library will try to complete the chain from the
+available CA certificates in the trusted CA storage, see
+L<SSL_CTX_load_verify_locations(3)|SSL_CTX_load_verify_locations(3)>.
+
+The B<x509> certificate provided to SSL_CTX_add_extra_chain_cert() will be
+freed by the library when the B<SSL_CTX> is destroyed. An application
+B<should not> free the B<x509> object.
+
+=head1 RESTRICTIONS
+
+Only one set of extra chain certificates can be specified per SSL_CTX
+structure. Different chains for different certificates (for example if both
+RSA and DSA certificates are specified by the same server) or different SSL
+structures with the same parent SSL_CTX cannot be specified using this

+be used instead.

+=head1 DESCRIPTION
+
+SSL_CTX_add_session() adds the session B<c> to the context B<ctx>. The
+reference count for session B<c> is incremented by 1. If a session with
+the same session id already exists, the old session is removed by calling
+L<SSL_SESSION_free(3)|SSL_SESSION_free(3)>.
+
+SSL_CTX_remove_session() removes the session B<c> from the context B<ctx>.
+L<SSL_SESSION_free(3)|SSL_SESSION_free(3)> is called once for B<c>.
+
+SSL_add_session() and SSL_remove_session() are synonyms for their
+SSL_CTX_*() counterparts.
+
+=head1 NOTES
+
+When adding a new session to the internal session cache, it is examined
+whether a session with the same session id already exists. In this case
+it is assumed that both sessions are identical. If the same session is
+stored in a different SSL_SESSION object, The old session is
+removed and replaced by the new session. If the session is actually
+identical (the SSL_SESSION object is identical), SSL_CTX_add_session()
+is a no-op, and the return value is 0.
+
+If a server SSL_CTX is configured with the SSL_SESS_CACHE_NO_INTERNAL_STORE
+flag then the internal cache will not be populated automatically by new
+sessions negotiated by the SSL/TLS implementation, even though the internal
+cache will be searched automatically for session-resume requests (the
+latter can be suppressed by SSL_SESS_CACHE_NO_INTERNAL_LOOKUP). So the
+application can use SSL_CTX_add_session() directly to have full control
+over the sessions that can be resumed if desired.

+
+SSL_flush_sessions() is a synonym for SSL_CTX_flush_sessions().
+
+=head1 NOTES
+
+If enabled, the internal session cache will collect all sessions established
+up to the specified maximum number (see SSL_CTX_sess_set_cache_size()).
+As sessions will not be reused ones they are expired, they should be
+removed from the cache to save resources. This can either be done
+ automatically whenever 255 new sessions were established (see
+L<SSL_CTX_set_session_cache_mode(3)|SSL_CTX_set_session_cache_mode(3)>)
+or manually by calling SSL_CTX_flush_sessions(). 
+
+The parameter B<tm> specifies the time which should be used for the
+expiration test, in most cases the actual time given by time(0)
+will be used.
+
+SSL_CTX_flush_sessions() will only check sessions stored in the internal
+cache. When a session is found and removed, the remove_session_cb is however
+called to synchronize with the external cache (see

+SSL_CTX_load_verify_locations - set default locations for trusted CA

+
+=head1 SYNOPSIS

+
+ int SSL_CTX_load_verify_locations(SSL_CTX *ctx, const char *CAfile,
+                                   const char *CApath);
+
+=head1 DESCRIPTION
+
+SSL_CTX_load_verify_locations() specifies the locations for B<ctx>, at
+which CA certificates for verification purposes are located. The certificates
+available via B<CAfile> and B<CApath> are trusted.
+
+=head1 NOTES
+
+If B<CAfile> is not NULL, it points to a file of CA certificates in PEM
+format. The file can contain several CA certificates identified by
+
+ -----BEGIN CERTIFICATE-----
+ ... (CA certificate in base64 encoding) ...
+ -----END CERTIFICATE-----
+
+sequences. Before, between, and after the certificates text is allowed
+which can be used e.g. for descriptions of the certificates.
+
+The B<CAfile> is processed on execution of the SSL_CTX_load_verify_locations()
+function.
+
+If B<CApath> is not NULL, it points to a directory containing CA certificates
+in PEM format. The files each contain one CA certificate. The files are
+looked up by the CA subject name hash value, which must hence be available.
+If more than one CA certificate with the same name hash value exist, the
+extension must be different (e.g. 9d66eef0.0, 9d66eef0.1 etc). The search
+is performed in the ordering of the extension number, regardless of other
+properties of the certificates.
+Use the B<c_rehash> utility to create the necessary links.
+
+The certificates in B<CApath> are only looked up when required, e.g. when
+building the certificate chain or when actually performing the verification
+of a peer certificate.
+
+When looking up CA certificates, the OpenSSL library will first search the
+certificates in B<CAfile>, then those in B<CApath>. Certificate matching
+is done based on the subject name, the key identifier (if present), and the
+serial number as taken from the certificate to be verified. If these data
+do not match, the next certificate will be tried. If a first certificate
+matching the parameters is found, the verification process will be performed;
+no other certificates for the same parameters will be searched in case of
+failure.
+
+In server mode, when requesting a client certificate, the server must send
+the list of CAs of which it will accept client certificates. This list
+is not influenced by the contents of B<CAfile> or B<CApath> and must
+explicitly be set using the
+L<SSL_CTX_set_client_CA_list(3)|SSL_CTX_set_client_CA_list(3)>
+family of functions.
+
+When building its own certificate chain, an OpenSSL client/server will
+try to fill in missing certificates from B<CAfile>/B<CApath>, if the
+certificate chain was not explicitly specified (see
+L<SSL_CTX_add_extra_chain_cert(3)|SSL_CTX_add_extra_chain_cert(3)>,
+L<SSL_CTX_use_certificate(3)|SSL_CTX_use_certificate(3)>.
+
+=head1 WARNINGS
+
+If several CA certificates matching the name, key identifier, and serial
+number condition are available, only the first one will be examined. This
+may lead to unexpected results if the same CA certificate is available
+with different expiration dates. If a "certificate expired" verification
+error occurs, no other certificate will be searched. Make sure to not
+have expired certificates mixed with valid ones.
+
+=head1 EXAMPLES
+
+Generate a CA certificate file with descriptive text from the CA certificates
+ca1.pem ca2.pem ca3.pem:
+
+ #!/bin/sh
+ rm CAfile.pem
+ for i in ca1.pem ca2.pem ca3.pem ; do
+   openssl x509 -in $i -text >> CAfile.pem
+ done
+
+Prepare the directory /some/where/certs containing several CA certificates
+for use as B<CApath>:
+
+ cd /some/where/certs
+ c_rehash .
+
+=head1 RETURN VALUES
+
+The following return values can occur:
+
+=over 4
+
+=item Z<>0
+
+The operation failed because B<CAfile> and B<CApath> are NULL or the
+processing at one of the locations specified failed. Check the error

+=head1 DESCRIPTION
+
+SSL_CTX_new() creates a new B<SSL_CTX> object as framework to establish
+TLS/SSL enabled connections.
+
+=head1 NOTES
+
+The SSL_CTX object uses B<method> as connection method. The methods exist
+in a generic type (for client and server use), a server only type, and a
+client only type. B<method> can be of the following types:
+
+=over 4
+
+=item SSLv23_method(), SSLv23_server_method(), SSLv23_client_method()
+
+These are the general-purpose I<version-flexible> SSL/TLS methods.
+The actual protocol version used will be negotiated to the highest version
+mutually supported by the client and the server.
+The supported protocols are SSLv2, SSLv3, TLSv1, TLSv1.1 and TLSv1.2.
+Most applications should use these method, and avoid the version specific
+methods described below.
+
+The list of protocols available can be further limited using the
+B<SSL_OP_NO_SSLv2>, B<SSL_OP_NO_SSLv3>, B<SSL_OP_NO_TLSv1>,
+B<SSL_OP_NO_TLSv1_1> and B<SSL_OP_NO_TLSv1_2> options of the
+L<SSL_CTX_set_options(3)> or L<SSL_set_options(3)> functions.
+Clients should avoid creating "holes" in the set of protocols they support,
+when disabling a protocol, make sure that you also disable either all previous
+or all subsequent protocol versions.
+In clients, when a protocol version is disabled without disabling I<all>
+previous protocol versions, the effect is to also disable all subsequent
+protocol versions.
+
+The SSLv2 and SSLv3 protocols are deprecated and should generally not be used.
+Applications should typically use L<SSL_CTX_set_options(3)> in combination with
+the B<SSL_OP_NO_SSLv3> flag to disable negotiation of SSLv3 via the above
+I<version-flexible> SSL/TLS methods.
+The B<SSL_OP_NO_SSLv2> option is set by default, and would need to be cleared
+via L<SSL_CTX_clear_options(3)> in order to enable negotiation of SSLv2.

+=head1 DESCRIPTION
+
+SSL_CTX_sess_set_cache_size() sets the size of the internal session cache
+of context B<ctx> to B<t>.
+This value is a hint and not an absolute; see the notes below.
+
+SSL_CTX_sess_get_cache_size() returns the currently valid session cache size.
+
+=head1 NOTES
+
+The internal session cache size is SSL_SESSION_CACHE_MAX_SIZE_DEFAULT,
+currently 1024*20, so that up to 20000 sessions can be held. This size
+can be modified using the SSL_CTX_sess_set_cache_size() call. A special
+case is the size 0, which is used for unlimited size.
+
+If adding the session makes the cache exceed its size, then unused
+sessions are dropped from the end of the cache.
+Cache space may also be reclaimed by calling
+L<SSL_CTX_flush_sessions(3)|SSL_CTX_flush_sessions(3)> to remove
+expired sessions.
+
+If the size of the session cache is reduced and more sessions are already
+in the session cache, old session will be removed at the next time a
+session shall be added. This removal is not synchronized with the
+expiration of sessions.

+=head1 DESCRIPTION
+
+SSL_CTX_sess_set_new_cb() sets the callback function, which is automatically
+called whenever a new session was negotiated.
+
+SSL_CTX_sess_set_remove_cb() sets the callback function, which is
+automatically called whenever a session is removed by the SSL engine,
+because it is considered faulty or the session has become obsolete because
+of exceeding the timeout value.
+
+SSL_CTX_sess_set_get_cb() sets the callback function which is called,
+whenever a SSL/TLS client proposed to resume a session but the session
+could not be found in the internal session cache (see
+L<SSL_CTX_set_session_cache_mode(3)|SSL_CTX_set_session_cache_mode(3)>).
+(SSL/TLS server only.)
+
+SSL_CTX_sess_get_new_cb(), SSL_CTX_sess_get_remove_cb(), and
+SSL_CTX_sess_get_get_cb() allow to retrieve the function pointers of the
+provided callback functions. If a callback function has not been set,
+the NULL pointer is returned.
+
+=head1 NOTES
+
+In order to allow external session caching, synchronization with the internal
+session cache is realized via callback functions. Inside these callback
+functions, session can be saved to disk or put into a database using the
+L<d2i_SSL_SESSION(3)|d2i_SSL_SESSION(3)> interface.
+
+The new_session_cb() is called, whenever a new session has been negotiated
+and session caching is enabled (see
+L<SSL_CTX_set_session_cache_mode(3)|SSL_CTX_set_session_cache_mode(3)>).
+The new_session_cb() is passed the B<ssl> connection and the ssl session
+B<sess>. If the callback returns B<0>, the session will be immediately
+removed again.
+
+The remove_session_cb() is called, whenever the SSL engine removes a session
+from the internal cache. This happens when the session is removed because
+it is expired or when a connection was not shutdown cleanly. It also happens
+for all sessions in the internal session cache when
+L<SSL_CTX_free(3)|SSL_CTX_free(3)> is called. The remove_session_cb() is passed
+the B<ctx> and the ssl session B<sess>. It does not provide any feedback.
+
+The get_session_cb() is only called on SSL/TLS servers with the session id
+proposed by the client. The get_session_cb() is always called, also when
+session caching was disabled. The get_session_cb() is passed the
+B<ssl> connection, the session id of length B<length> at the memory location
+B<data>. With the parameter B<copy> the callback can require the
+SSL engine to increment the reference count of the SSL_SESSION object,
+Normally the reference count is not incremented and therefore the
+session must not be explicitly freed with
+L<SSL_SESSION_free(3)|SSL_SESSION_free(3)>.

+
+=head1 DESCRIPTION
+
+SSL_CTX_set1_curves() sets the supported curves for B<ctx> to B<clistlen>
+curves in the array B<clist>. The array consist of all NIDs of curves in
+preference order. For a TLS client the curves are used directly in the
+supported curves extension. For a TLS server the curves are used to 
+determine the set of shared curves.
+
+SSL_CTX_set1_curves_list() sets the supported curves for B<ctx> to
+string B<list>. The string is a colon separated list of curve NIDs or
+names, for example "P-521:P-384:P-256".
+
+SSL_set1_curves() and SSL_set1_curves_list() are similar except they set
+supported curves for the SSL structure B<ssl>.
+
+SSL_get1_curves() returns the set of supported curves sent by a client
+in the supported curves extension. It returns the total number of 
+supported curves. The B<curves> parameter can be B<NULL> to simply
+return the number of curves for memory allocation purposes. The
+B<curves> array is in the form of a set of curve NIDs in preference
+order. It can return zero if the client did not send a supported curves
+extension.
+
+SSL_get_shared_curve() returns shared curve B<n> for a server-side
+SSL B<ssl>. If B<n> is -1 then the total number of shared curves is
+returned, which may be zero. Other than for diagnostic purposes,
+most applications will only be interested in the first shared curve
+so B<n> is normally set to zero. If the value B<n> is out of range,
+NID_undef is returned.
+
+SSL_CTX_set_ecdh_auto() and SSL_set_ecdh_auto() set automatic curve
+selection for server B<ctx> or B<ssl> to B<onoff>. If B<onoff> is 1 then 
+the highest preference curve is automatically used for ECDH temporary
+keys used during key exchange.
+
+All these functions are implemented as macros.
+
+=head1 NOTES
+
+If an application wishes to make use of several of these functions for
+configuration purposes either on a command line or in a file it should
+consider using the SSL_CONF interface instead of manually parsing options.
+
+The functions SSL_CTX_set_ecdh_auto() and SSL_set_ecdh_auto() can be used to
+make a server always choose the most appropriate curve for a client. If set
+it will override any temporary ECDH parameters set by a server. Previous
+versions of OpenSSL could effectively only use a single ECDH curve set
+using a function such as SSL_CTX_set_ecdh_tmp(). Newer applications should
+just call:
+
+ SSL_CTX_set_ecdh_auto(ctx, 1);
+
+and they will automatically support ECDH using the most appropriate shared
+curve.
+

+SSL_set1_curves_list(), SSL_CTX_set_ecdh_auto() and SSL_set_ecdh_auto()

+
+SSL_get1_curves() returns the number of curves, which may be zero.
+
+SSL_get_shared_curve() returns the NID of shared curve B<n> or NID_undef if there
+is no shared curve B<n>; or the total number of shared curves if B<n>

+
+=head1 NOTES
+
+The stores pointers associated with an SSL_CTX structure are copied to any SSL
+structures when SSL_new() is called. As a result SSL structures will not be
+affected if the parent SSL_CTX store pointer is set to a new value.
+
+The verification store is used to verify the certificate chain sent by the
+peer: that is an SSL/TLS client will use the verification store to verify
+the server's certificate chain and a SSL/TLS server will use it to verify
+any client certificate chain.
+
+The chain store is used to build the certificate chain.
+
+If the mode B<SSL_MODE_NO_AUTO_CHAIN> is set or a certificate chain is

+automatic chain building is disabled.
+
+If the mode B<SSL_MODE_NO_AUTO_CHAIN> is set then automatic chain building
+is disabled.
+
+If the chain or the verification store is not set then the store associated
+with the parent SSL_CTX is used instead to retain compatibility with previous

+
+SSL_CTX_set_alpn_protos() and SSL_set_alpn_protos() are used by the client to
+set the list of protocols available to be negotiated. The B<protos> must be in
+protocol-list format, described below. The length of B<protos> is specified in
+B<protos_len>.
+
+SSL_CTX_set_alpn_select_cb() sets the application callback B<cb> used by a
+server to select which protocol to use for the incoming connection. When B<cb>
+is NULL, ALPN is not used. The B<arg> value is a pointer which is passed to
+the application callback.
+
+B<cb> is the application defined callback. The B<in>, B<inlen> parameters are a
+vector in protocol-list format. The value of the B<out>, B<outlen> vector
+should be set to the value of a single protocol selected from the B<in>,
+B<inlen> vector. The B<arg> parameter is the pointer set via
+SSL_CTX_set_alpn_select_cb().
+
+SSL_select_next_proto() is a helper function used to select protocols. It
+implements the standard protocol selection. It is expected that this function
+is called from the application callback B<cb>. The protocol data in B<server>,
+B<server_len> and B<client>, B<client_len> must be in the protocol-list format
+described below. The first item in the B<server>, B<server_len> list that
+matches an item in the B<client>, B<client_len> list is selected, and returned
+in B<out>, B<outlen>. The B<out> value will point into either B<server> or
+B<client>, so it should be copied immediately. If no match is found, the first
+item in B<client>, B<client_len> is returned in B<out>, B<outlen>. This
+function can also be used in the NPN callback.
+
+SSL_get0_alpn_selected() returns a pointer to the selected protocol in B<data>
+with length B<len>. It is not NUL-terminated. B<data> is set to NULL and B<len>
+is set to 0 if no protocol has been selected. B<data> must not be freed.
+
+=head1 NOTES
+
+The protocol-lists must be in wire-format, which is defined as a vector of
+non-empty, 8-bit length-prefixed, byte strings. The length-prefix byte is not
+included in the length. Each string is limited to 255 bytes. A byte-string
+length of 0 is invalid. A truncated byte-string is invalid. The length of the
+vector is not in the vector itself, but in a separate variable.
+
+Example:
+
+ unsigned char vector[] = {
+     6, 's', 'p', 'd', 'y', '/', '1',
+     8, 'h', 't', 't', 'p', '/', '1', '.', '1'
+ };
+ unsigned int length = sizeof(vector);
+
+The ALPN callback is executed after the servername callback; as that servername
+callback may update the SSL_CTX, and subsequently, the ALPN callback.
+
+If there is no ALPN proposed in the ClientHello, the ALPN callback is not
+invoked.

+SSL_CTX_set_cert_cb, SSL_set_cert_cb - handle certificate callback function

+
+ void SSL_CTX_set_cert_cb(SSL_CTX *c, int (*cert_cb)(SSL *ssl, void *arg), void *arg);
+ void SSL_set_cert_cb(SSL *s, int (*cert_cb)(SSL *ssl, void *arg), void *arg);
+
+ int (*cert_cb)(SSL *ssl, void *arg);
+
+=head1 DESCRIPTION
+
+SSL_CTX_set_cert_cb() and SSL_set_cert_cb() sets the B<cert_cb()> callback,
+B<arg> value is pointer which is passed to the application callback.
+
+When B<cert_cb()> is NULL, no callback function is used.
+
+cert_cb() is the application defined callback. It is called before a
+certificate will be used by a client or server. The callback can then inspect
+the passed B<ssl> structure and set or clear any appropriate certificates. If
+the callback is successful it B<MUST> return 1 even if no certificates have
+been set. A zero is returned on error which will abort the handshake with a
+fatal internal error alert. A negative return value will suspend the handshake
+and the handshake function will return immediately.
+L<SSL_get_error(3)|SSL_get_error(3)> will return SSL_ERROR_WANT_X509_LOOKUP to
+indicate, that the handshake was suspended. The next call to the handshake
+function will again lead to the call of cert_cb(). It is the job of the
+cert_cb() to store information about the state of the last call,
+if required to continue.
+
+=head1 NOTES
+
+An application will typically call SSL_use_certificate() and
+SSL_use_PrivateKey() to set the end entity certificate and private key.
+It can add intermediate and optionally the root CA certificates using
+SSL_add1_chain_cert().
+
+It might also call SSL_certs_clear() to delete any certificates associated
+with the B<SSL> object.
+
+The certificate callback functionality supercedes the (largely broken)
+functionality provided by the old client certificate callback interface.
+It is B<always> called even is a certificate is already set so the callback
+can modify or delete the existing certificate.
+
+A more advanced callback might examine the handshake parameters and set
+whatever chain is appropriate. For example a legacy client supporting only
+TLS v1.0 might receive a certificate chain signed using SHA1 whereas a
+TLS v1.2 client which advertises support for SHA256 could receive a chain
+using SHA256.
+
+Normal server sanity checks are performed on any certificates set
+by the callback. So if an EC chain is set for a curve the client does not
+support it will B<not> be used.

+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ void SSL_CTX_set_cert_store(SSL_CTX *ctx, X509_STORE *store);
+ X509_STORE *SSL_CTX_get_cert_store(const SSL_CTX *ctx);
+
+=head1 DESCRIPTION
+
+SSL_CTX_set_cert_store() sets/replaces the certificate verification storage
+of B<ctx> to/with B<store>. If another X509_STORE object is currently
+set in B<ctx>, it will be X509_STORE_free()ed.
+
+SSL_CTX_get_cert_store() returns a pointer to the current certificate
+verification storage.
+
+=head1 NOTES
+
+In order to verify the certificates presented by the peer, trusted CA
+certificates must be accessed. These CA certificates are made available
+via lookup methods, handled inside the X509_STORE. From the X509_STORE
+the X509_STORE_CTX used when verifying certificates is created.
+
+Typically the trusted certificate store is handled indirectly via using
+L<SSL_CTX_load_verify_locations(3)|SSL_CTX_load_verify_locations(3)>.
+Using the SSL_CTX_set_cert_store() and SSL_CTX_get_cert_store() functions
+it is possible to manipulate the X509_STORE object beyond the
+L<SSL_CTX_load_verify_locations(3)|SSL_CTX_load_verify_locations(3)>
+call.
+
+Currently no detailed documentation on how to use the X509_STORE
+object is available. Not all members of the X509_STORE are used when
+the verification takes place. So will e.g. the verify_callback() be
+overridden with the verify_callback() set via the
+L<SSL_CTX_set_verify(3)|SSL_CTX_set_verify(3)> family of functions.
+This document must therefore be updated when documentation about the
+X509_STORE object and its handling becomes available.
+
+=head1 RESTRICTIONS
+
+The X509_STORE structure used by an SSL_CTX is used for verifying peer
+certificates and building certificate chains, it is also shared by
+every child SSL structure. Applications wanting finer control can use 
+functions such as SSL_CTX_set1_verify_cert_store() instead.
+

+SSL_CTX_set_cert_store() does not return diagnostic output.

+
+ #include <openssl/ssl.h>
+
+ void SSL_CTX_set_cert_verify_callback(SSL_CTX *ctx, int (*callback)(X509_STORE_CTX *,void *), void *arg);
+
+=head1 DESCRIPTION
+
+SSL_CTX_set_cert_verify_callback() sets the verification callback function for
+I<ctx>. SSL objects that are created from I<ctx> inherit the setting valid at
+the time when L<SSL_new(3)|SSL_new(3)> is called.
+
+=head1 NOTES
+
+Whenever a certificate is verified during a SSL/TLS handshake, a verification
+function is called. If the application does not explicitly specify a
+verification callback function, the built-in verification function is used.
+If a verification callback I<callback> is specified via
+SSL_CTX_set_cert_verify_callback(), the supplied callback function is called
+instead. By setting I<callback> to NULL, the default behaviour is restored.
+
+When the verification must be performed, I<callback> will be called with
+the arguments callback(X509_STORE_CTX *x509_store_ctx, void *arg). The 
+argument I<arg> is specified by the application when setting I<callback>.
+
+I<callback> should return 1 to indicate verification success and 0 to
+indicate verification failure. If SSL_VERIFY_PEER is set and I<callback>
+returns 0, the handshake will fail. As the verification procedure may
+allow to continue the connection in case of failure (by always returning 1)
+the verification result must be set in any case using the B<error>
+member of I<x509_store_ctx> so that the calling application will be informed
+about the detailed result of the verification procedure! 
+
+Within I<x509_store_ctx>, I<callback> has access to the I<verify_callback>
+function set using L<SSL_CTX_set_verify(3)|SSL_CTX_set_verify(3)>.
+
+=head1 WARNINGS
+
+Do not mix the verification callback described in this function with the
+B<verify_callback> function called during the verification process. The
+latter is set using the L<SSL_CTX_set_verify(3)|SSL_CTX_set_verify(3)>
+family of functions.
+
+Providing a complete verification procedure including certificate purpose
+settings etc is a complex task. The built-in procedure is quite powerful
+and in most cases it should be sufficient to modify its behaviour using
+the B<verify_callback> function.

+
+=head1 HISTORY
+
+Previous to OpenSSL 0.9.7, the I<arg> argument to B<SSL_CTX_set_cert_verify_callback>
+was ignored, and I<callback> was called simply as
+ int (*callback)(X509_STORE_CTX *)
+To compile software written for previous versions of OpenSSL, a dummy
+argument will have to be added to I<callback>.

+ #include <openssl/ssl.h>
+

+ int SSL_set_cipher_list(SSL *ssl, const char *str);
+
+=head1 DESCRIPTION
+
+SSL_CTX_set_cipher_list() sets the list of available ciphers for B<ctx>
+using the control string B<str>. The format of the string is described
+in L<ciphers(1)|ciphers(1)>. The list of ciphers is inherited by all
+B<ssl> objects created from B<ctx>.
+
+SSL_set_cipher_list() sets the list of ciphers only for B<ssl>.
+
+=head1 NOTES
+
+The control string B<str> should be universally usable and not depend
+on details of the library configuration (ciphers compiled in). Thus no
+syntax checking takes place. Items that are not recognized, because the
+corresponding ciphers are not compiled in or because they are mistyped,
+are simply ignored. Failure is only flagged if no ciphers could be collected
+at all.
+
+It should be noted, that inclusion of a cipher to be used into the list is
+a necessary condition. On the client side, the inclusion into the list is
+also sufficient. On the server side, additional restrictions apply. All ciphers
+have additional requirements. ADH ciphers don't need a certificate, but
+DH-parameters must have been set. All other ciphers need a corresponding
+certificate and key.
+
+A RSA cipher can only be chosen, when a RSA certificate is available.
+RSA export ciphers with a keylength of 512 bits for the RSA key require
+a temporary 512 bit RSA key, as typically the supplied key has a length
+of 1024 bit (see
+L<SSL_CTX_set_tmp_rsa_callback(3)|SSL_CTX_set_tmp_rsa_callback(3)>).
+RSA ciphers using DHE need a certificate and key and additional DH-parameters
+(see L<SSL_CTX_set_tmp_dh_callback(3)|SSL_CTX_set_tmp_dh_callback(3)>).
+
+A DSA cipher can only be chosen, when a DSA certificate is available.
+DSA ciphers always use DH key exchange and therefore need DH-parameters
+(see L<SSL_CTX_set_tmp_dh_callback(3)|SSL_CTX_set_tmp_dh_callback(3)>).
+
+When these conditions are not met for any cipher in the list (e.g. a
+client only supports export RSA ciphers with a asymmetric key length
+of 512 bits and the server is not configured to use temporary RSA
+keys), the "no shared cipher" (SSL_R_NO_SHARED_CIPHER) error is generated
+and the handshake will fail.
+
+If the cipher list does not contain any SSLv2 cipher suites (this is the
+default) then SSLv2 is effectively disabled and neither clients nor servers
+will attempt to use SSLv2.

+
+=head1 NOTES
+
+When a TLS/SSL server requests a client certificate (see
+B<SSL_CTX_set_verify(3)>), it sends a list of CAs, for which
+it will accept certificates, to the client.
+
+This list must explicitly be set using SSL_CTX_set_client_CA_list() for
+B<ctx> and SSL_set_client_CA_list() for the specific B<ssl>. The list
+specified overrides the previous setting. The CAs listed do not become
+trusted (B<list> only contains the names, not the complete certificates); use
+L<SSL_CTX_load_verify_locations(3)|SSL_CTX_load_verify_locations(3)> 
+to additionally load them for verification.
+
+If the list of acceptable CAs is compiled in a file, the
+L<SSL_load_client_CA_file(3)|SSL_load_client_CA_file(3)>
+function can be used to help importing the necessary data.
+
+SSL_CTX_add_client_CA() and SSL_add_client_CA() can be used to add additional
+items the list of client CAs. If no list was specified before using
+SSL_CTX_set_client_CA_list() or SSL_set_client_CA_list(), a new client
+CA list for B<ctx> or B<ssl> (as appropriate) is opened.
+
+These functions are only useful for TLS/SSL servers.

+
+=head1 DESCRIPTION
+
+SSL_CTX_set_client_cert_cb() sets the B<client_cert_cb()> callback, that is
+called when a client certificate is requested by a server and no certificate
+was yet set for the SSL object.
+
+When B<client_cert_cb()> is NULL, no callback function is used.
+
+SSL_CTX_get_client_cert_cb() returns a pointer to the currently set callback
+function.
+
+client_cert_cb() is the application defined callback. If it wants to
+set a certificate, a certificate/private key combination must be set
+using the B<x509> and B<pkey> arguments and "1" must be returned. The
+certificate will be installed into B<ssl>, see the NOTES and BUGS sections.
+If no certificate should be set, "0" has to be returned and no certificate
+will be sent. A negative return value will suspend the handshake and the
+handshake function will return immediately. L<SSL_get_error(3)|SSL_get_error(3)>
+will return SSL_ERROR_WANT_X509_LOOKUP to indicate, that the handshake was
+suspended. The next call to the handshake function will again lead to the call
+of client_cert_cb(). It is the job of the client_cert_cb() to store information
+about the state of the last call, if required to continue.
+
+=head1 NOTES
+
+During a handshake (or renegotiation) a server may request a certificate
+from the client. A client certificate must only be sent, when the server
+did send the request.
+
+When a certificate was set using the
+L<SSL_CTX_use_certificate(3)|SSL_CTX_use_certificate(3)> family of functions,
+it will be sent to the server. The TLS standard requires that only a
+certificate is sent, if it matches the list of acceptable CAs sent by the
+server. This constraint is violated by the default behavior of the OpenSSL
+library. Using the callback function it is possible to implement a proper
+selection routine or to allow a user interaction to choose the certificate to
+be sent.
+
+If a callback function is defined and no certificate was yet defined for the
+SSL object, the callback function will be called.
+If the callback function returns a certificate, the OpenSSL library
+will try to load the private key and certificate data into the SSL
+object using the SSL_use_certificate() and SSL_use_private_key() functions.
+Thus it will permanently install the certificate and key for this SSL
+object. It will not be reset by calling L<SSL_clear(3)|SSL_clear(3)>.
+If the callback returns no certificate, the OpenSSL library will not send
+a certificate.
+
+=head1 BUGS
+
+The client_cert_cb() cannot return a complete certificate chain, it can
+only return one client certificate. If the chain only has a length of 2,
+the root CA certificate may be omitted according to the TLS standard and
+thus a standard conforming answer can be sent to the server. For a
+longer chain, the client must send the complete chain (with the option
+to leave out the root CA certificate). This can only be accomplished by
+either adding the intermediate CA certificates into the trusted
+certificate store for the SSL_CTX object (resulting in having to add
+CA certificates that otherwise maybe would not be trusted), or by adding
+the chain certificates using the
+L<SSL_CTX_add_extra_chain_cert(3)|SSL_CTX_add_extra_chain_cert(3)>
+function, which is only available for the SSL_CTX object as a whole and that
+therefore probably can only apply for one client certificate, making
+the concept of the callback function (to allow the choice from several
+certificates) questionable.
+
+Once the SSL object has been used in conjunction with the callback function,
+the certificate will be set for the SSL object and will not be cleared
+even when L<SSL_clear(3)|SSL_clear(3)> is being called. It is therefore
+mandatory to destroy the SSL object using L<SSL_free(3)|SSL_free(3)>
+and create a new one to return to the previous state.

+=head1 DESCRIPTION
+
+SSL_CTX_add_client_custom_ext() adds a custom extension for a TLS client 
+with extension type B<ext_type> and callbacks B<add_cb>, B<free_cb> and
+B<parse_cb>.
+
+SSL_CTX_add_server_custom_ext() adds a custom extension for a TLS server 
+with extension type B<ext_type> and callbacks B<add_cb>, B<free_cb> and
+B<parse_cb>.
+
+In both cases the extension type must not be handled by OpenSSL internally
+or an error occurs.
+
+SSL_extension_supported() returns 1 if the extension B<ext_type> is handled
+internally by OpenSSL and 0 otherwise.
+
+=head1 EXTENSION CALLBACKS
+
+The callback B<add_cb> is called to send custom extension data to be 
+included in ClientHello for TLS clients or ServerHello for servers. The
+B<ext_type> parameter is set to the extension type which will be added and
+B<add_arg> to the value set when the extension handler was added.
+
+If the application wishes to include the extension B<ext_type> it should
+set B<*out> to the extension data, set B<*outlen> to the length of the
+extension data and return 1.
+
+If the B<add_cb> does not wish to include the extension it must return 0.
+
+If B<add_cb> returns -1 a fatal handshake error occurs using the TLS
+alert value specified in B<*al>.
+
+For clients (but not servers) if B<add_cb> is set to NULL a zero length
+extension is added for B<ext_type>.
+
+For clients every registered B<add_cb> is always called to see if the
+application wishes to add an extension to ClientHello.
+
+For servers every registered B<add_cb> is called once if and only if the
+corresponding extension was received in ClientHello to see if the application
+wishes to add the extension to ServerHello. That is, if no corresponding extension
+was received in ClientHello then B<add_cb> will not be called.
+
+If an extension is added (that is B<add_cb> returns 1) B<free_cb> is called
+(if it is set) with the value of B<out> set by the add callback. It can be
+used to free up any dynamic extension data set by B<add_cb>. Since B<out> is
+constant (to permit use of constant data in B<add_cb>) applications may need to
+cast away const to free the data.
+
+The callback B<parse_cb> receives data for TLS extensions. For TLS clients
+the extension data will come from ServerHello and for TLS servers it will
+come from ClientHello.
+
+The extension data consists of B<inlen> bytes in the buffer B<in> for the
+extension B<extension_type>.
+
+If the B<parse_cb> considers the extension data acceptable it must return
+1. If it returns 0 or a negative value a fatal handshake error occurs
+using the TLS alert value specified in B<*al>.
+
+The buffer B<in> is a temporary internal buffer which will not be valid after
+the callback returns.
+
+=head1 NOTES
+
+The B<add_arg> and B<parse_arg> parameters can be set to arbitrary values
+which will be passed to the corresponding callbacks. They can, for example,
+be used to store the extension data received in a convenient structure or
+pass the extension data to be added or freed when adding extensions.
+
+The B<ext_type> parameter corresponds to the B<extension_type> field of
+RFC5246 et al. It is B<not> a NID.
+
+If the same custom extension type is received multiple times a fatal
+B<decode_error> alert is sent and the handshake aborts. If a custom extension
+is received in ServerHello which was not sent in ClientHello a fatal
+B<unsupported_extension> alert is sent and the handshake is aborted. The
+ServerHello B<add_cb> callback is only called if the corresponding extension
+was received in ClientHello. This is compliant with the TLS specifications.
+This behaviour ensures that each callback is called at most once and that
+an application can never send unsolicited extensions.
+
+=head1 RETURN VALUES
+
+SSL_CTX_add_client_custom_ext() and SSL_CTX_add_server_custom_ext() return 1 for
+success and 0 for failure. A failure can occur if an attempt is made to
+add the same B<ext_type> more than once, if an attempt is made to use an
+extension type handled internally by OpenSSL or if an internal error occurs
+(for example a memory allocation failure).
+
+SSL_extension_supported() returns 1 if the extension B<ext_type> is handled
+internally by OpenSSL and 0 otherwise.

+SSL_CTX_set_default_passwd_cb, SSL_CTX_set_default_passwd_cb_userdata - set passwd callback for encrypted PEM file handling

+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ void SSL_CTX_set_default_passwd_cb(SSL_CTX *ctx, pem_password_cb *cb);
+ void SSL_CTX_set_default_passwd_cb_userdata(SSL_CTX *ctx, void *u);

+
+=head1 DESCRIPTION
+
+SSL_CTX_set_default_passwd_cb() sets the default password callback called
+when loading/storing a PEM certificate with encryption.
+
+SSL_CTX_set_default_passwd_cb_userdata() sets a pointer to B<userdata> which
+will be provided to the password callback on invocation.
+
+The pem_passwd_cb(), which must be provided by the application, hands back the
+password to be used during decryption. On invocation a pointer to B<userdata>
+is provided. The pem_passwd_cb must write the password into the provided buffer
+B<buf> which is of size B<size>. The actual length of the password must
+be returned to the calling function. B<rwflag> indicates whether the
+callback is used for reading/decryption (rwflag=0) or writing/encryption
+(rwflag=1).
+
+=head1 NOTES
+
+When loading or storing private keys, a password might be supplied to
+protect the private key. The way this password can be supplied may depend
+on the application. If only one private key is handled, it can be practical
+to have pem_passwd_cb() handle the password dialog interactively. If several
+keys have to be handled, it can be practical to ask for the password once,
+then keep it in memory and use it several times. In the last case, the
+password could be stored into the B<userdata> storage and the
+pem_passwd_cb() only returns the password already stored.
+
+When asking for the password interactively, pem_passwd_cb() can use
+B<rwflag> to check, whether an item shall be encrypted (rwflag=1).
+In this case the password dialog may ask for the same password twice
+for comparison in order to catch typos, that would make decryption
+impossible.
+
+Other items in PEM formatting (certificates) can also be encrypted, it is
+however not usual, as certificate information is considered public.
+

+=head1 DESCRIPTION
+
+SSL_CTX_set_generate_session_id() sets the callback function for generating
+new session ids for SSL/TLS sessions for B<ctx> to be B<cb>.
+
+SSL_set_generate_session_id() sets the callback function for generating
+new session ids for SSL/TLS sessions for B<ssl> to be B<cb>.
+
+SSL_has_matching_session_id() checks, whether a session with id B<id>
+(of length B<id_len>) is already contained in the internal session cache
+of the parent context of B<ssl>.
+
+=head1 NOTES
+
+When a new session is established between client and server, the server
+generates a session id. The session id is an arbitrary sequence of bytes.
+The length of the session id is 16 bytes for SSLv2 sessions and between
+1 and 32 bytes for SSLv3/TLSv1. The session id is not security critical
+but must be unique for the server. Additionally, the session id is
+transmitted in the clear when reusing the session so it must not contain
+sensitive information.
+
+Without a callback being set, an OpenSSL server will generate a unique
+session id from pseudo random numbers of the maximum possible length.
+Using the callback function, the session id can be changed to contain
+additional information like e.g. a host id in order to improve load balancing
+or external caching techniques.
+
+The callback function receives a pointer to the memory location to put
+B<id> into and a pointer to the maximum allowed length B<id_len>. The
+buffer at location B<id> is only guaranteed to have the size B<id_len>.
+The callback is only allowed to generate a shorter id and reduce B<id_len>;
+the callback B<must never> increase B<id_len> or write to the location
+B<id> exceeding the given limit.
+
+If a SSLv2 session id is generated and B<id_len> is reduced, it will be
+restored after the callback has finished and the session id will be padded
+with 0x00. It is not recommended to change the B<id_len> for SSLv2 sessions.
+The callback can use the L<SSL_get_version(3)|SSL_get_version(3)> function
+to check, whether the session is of type SSLv2.
+
+The location B<id> is filled with 0x00 before the callback is called, so the
+callback may only fill part of the possible length and leave B<id_len>
+untouched while maintaining reproducibility.
+
+Since the sessions must be distinguished, session ids must be unique.
+Without the callback a random number is used, so that the probability
+of generating the same session id is extremely small (2^128 possible ids
+for an SSLv2 session, 2^256 for SSLv3/TLSv1). In order to assure the
+uniqueness of the generated session id, the callback must call
+SSL_has_matching_session_id() and generate another id if a conflict occurs.
+If an id conflict is not resolved, the handshake will fail.
+If the application codes e.g. a unique host id, a unique process number, and
+a unique sequence number into the session id, uniqueness could easily be
+achieved without randomness added (it should however be taken care that
+no confidential information is leaked this way). If the application can not
+guarantee uniqueness, it is recommended to use the maximum B<id_len> and
+fill in the bytes not used to code special information with random data
+to avoid collisions.
+
+SSL_has_matching_session_id() will only query the internal session cache,
+not the external one. Since the session id is generated before the
+handshake is completed, it is not immediately added to the cache. If
+another thread is using the same internal session cache, a race condition
+can occur in that another thread generates the same session id.
+Collisions can also occur when using an external session cache, since
+the external cache is not tested with SSL_has_matching_session_id()
+and the same race condition applies.
+
+When calling SSL_has_matching_session_id() for an SSLv2 session with
+reduced B<id_len>, the match operation will be performed using the
+fixed length required and with a 0x00 padded id.
+
+The callback must return 0 if it cannot generate a session id for whatever
+reason and return 1 on success.
+
+=head1 EXAMPLES
+
+The callback function listed will generate a session id with the
+server id given, and will fill the rest with pseudo random bytes:
+
+ const char session_id_prefix = "www-18";
+
+ #define MAX_SESSION_ID_ATTEMPTS 10

+=head1 DESCRIPTION
+
+SSL_CTX_set_max_cert_list() sets the maximum size allowed for the peer's
+certificate chain for all SSL objects created from B<ctx> to be <size> bytes.
+The SSL objects inherit the setting valid for B<ctx> at the time
+L<SSL_new(3)|SSL_new(3)> is being called.
+
+SSL_CTX_get_max_cert_list() returns the currently set maximum size for B<ctx>.
+
+SSL_set_max_cert_list() sets the maximum size allowed for the peer's
+certificate chain for B<ssl> to be <size> bytes. This setting stays valid
+until a new value is set.
+
+SSL_get_max_cert_list() returns the currently set maximum size for B<ssl>.
+
+=head1 NOTES
+
+During the handshake process, the peer may send a certificate chain.
+The TLS/SSL standard does not give any maximum size of the certificate chain.
+The OpenSSL library handles incoming data by a dynamically allocated buffer.
+In order to prevent this buffer from growing without bounds due to data
+received from a faulty or malicious peer, a maximum size for the certificate
+chain is set.
+
+The default value for the maximum certificate chain size is 100kB (30kB
+on the 16bit DOS platform). This should be sufficient for usual certificate
+chains (OpenSSL's default maximum chain length is 10, see
+L<SSL_CTX_set_verify(3)|SSL_CTX_set_verify(3)>, and certificates
+without special extensions have a typical size of 1-2kB).
+
+For special applications it can be necessary to extend the maximum certificate
+chain size allowed to be sent by the peer, see e.g. the work on
+"Internet X.509 Public Key Infrastructure Proxy Certificate Profile"
+and "TLS Delegation Protocol" at http://www.ietf.org/ and
+http://www.globus.org/ .
+
+Under normal conditions it should never be necessary to set a value smaller
+than the default, as the buffer is handled dynamically and only uses the
+memory actually required by the data sent by the peer.
+
+If the maximum certificate chain size allowed is exceeded, the handshake will
+fail with a SSL_R_EXCESSIVE_MESSAGE_SIZE error.

+
+=head1 NOTES
+
+The following mode changes are available:
+
+=over 4
+
+=item SSL_MODE_ENABLE_PARTIAL_WRITE
+
+Allow SSL_write(..., n) to return r with 0 < r < n (i.e. report success
+when just a single record has been written). When not set (the default),
+SSL_write() will only report success once the complete chunk was written.
+Once SSL_write() returns with r, r bytes have been successfully written
+and the next call to SSL_write() must only send the n-r bytes left,
+imitating the behaviour of write().
+
+=item SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER
+
+Make it possible to retry SSL_write() with changed buffer location
+(the buffer contents must stay the same). This is not the default to avoid
+the misconception that non-blocking SSL_write() behaves like
+non-blocking write().
+
+=item SSL_MODE_AUTO_RETRY
+
+Never bother the application with retries if the transport is blocking.
+If a renegotiation take place during normal operation, a
+L<SSL_read(3)|SSL_read(3)> or L<SSL_write(3)|SSL_write(3)> would return
+with -1 and indicate the need to retry with SSL_ERROR_WANT_READ.
+In a non-blocking environment applications must be prepared to handle
+incomplete read/write operations.
+In a blocking environment, applications are not always prepared to
+deal with read/write operations returning without success report. The
+flag SSL_MODE_AUTO_RETRY will cause read/write operations to only
+return after the handshake and successful completion.
+
+=item SSL_MODE_RELEASE_BUFFERS
+
+When we no longer need a read buffer or a write buffer for a given SSL,
+then release the memory we were using to hold it.  Released memory is
+either appended to a list of unused RAM chunks on the SSL_CTX, or simply
+freed if the list of unused chunks would become longer than 
+SSL_CTX->freelist_max_len, which defaults to 32.  Using this flag can
+save around 34k per idle SSL connection.
+This flag has no effect on SSL v2 connections, or on DTLS connections.
+
+=item SSL_MODE_SEND_FALLBACK_SCSV
+
+Send TLS_FALLBACK_SCSV in the ClientHello.
+To be set only by applications that reconnect with a downgraded protocol
+version; see draft-ietf-tls-downgrade-scsv-00 for details.
+
+DO NOT ENABLE THIS if your application attempts a normal handshake.

+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ void SSL_CTX_set_msg_callback(SSL_CTX *ctx, void (*cb)(int write_p, int version, int content_type, const void *buf, size_t len, SSL *ssl, void *arg));

+ void SSL_set_msg_callback_arg(SSL *ssl, void *arg);
+
+=head1 DESCRIPTION
+
+SSL_CTX_set_msg_callback() or SSL_set_msg_callback() can be used to
+define a message callback function I<cb> for observing all SSL/TLS
+protocol messages (such as handshake messages) that are received or
+sent.  SSL_CTX_set_msg_callback_arg() and SSL_set_msg_callback_arg()
+can be used to set argument I<arg> to the callback function, which is
+available for arbitrary application use.
+
+SSL_CTX_set_msg_callback() and SSL_CTX_set_msg_callback_arg() specify
+default settings that will be copied to new B<SSL> objects by
+L<SSL_new(3)|SSL_new(3)>. SSL_set_msg_callback() and
+SSL_set_msg_callback_arg() modify the actual settings of an B<SSL>
+object. Using a B<0> pointer for I<cb> disables the message callback.
+
+When I<cb> is called by the SSL/TLS library for a protocol message,
+the function arguments have the following meaning:
+
+=over 4
+
+=item I<write_p>
+
+This flag is B<0> when a protocol message has been received and B<1>
+when a protocol message has been sent.
+
+=item I<version>
+
+The protocol version according to which the protocol message is
+interpreted by the library. Currently, this is one of
+B<SSL2_VERSION>, B<SSL3_VERSION> and B<TLS1_VERSION> (for SSL 2.0, SSL
+3.0 and TLS 1.0, respectively).
+
+=item I<content_type>
+
+In the case of SSL 2.0, this is always B<0>.  In the case of SSL 3.0
+or TLS 1.0, this is one of the B<ContentType> values defined in the
+protocol specification (B<change_cipher_spec(20)>, B<alert(21)>,
+B<handshake(22)>; but never B<application_data(23)> because the
+callback will only be called for protocol messages).
+
+=item I<buf>, I<len>
+
+I<buf> points to a buffer containing the protocol message, which
+consists of I<len> bytes. The buffer is no longer valid after the
+callback function has returned.
+
+=item I<ssl>
+
+The B<SSL> object that received or sent the message.
+
+=item I<arg>
+
+The user-defined argument optionally defined by
+SSL_CTX_set_msg_callback_arg() or SSL_set_msg_callback_arg().
+
+=back
+
+=head1 NOTES
+
+Protocol messages are passed to the callback function after decryption
+and fragment collection where applicable. (Thus record boundaries are
+not visible.)
+
+If processing a received protocol message results in an error,
+the callback function may not be called.  For example, the callback
+function will never see messages that are considered too large to be
+processed.
+
+Due to automatic protocol version negotiation, I<version> is not
+necessarily the protocol version used by the sender of the message: If
+a TLS 1.0 ClientHello message is received by an SSL 3.0-only server,
+I<version> will be B<SSL3_VERSION>.

+SSL_set_options() adds the options set via bitmask in B<options> to B<ssl>.

+SSL_CTX_get_options() returns the options set for B<ctx>.
+
+SSL_get_options() returns the options set for B<ssl>.
+
+SSL_get_secure_renegotiation_support() indicates whether the peer supports
+secure renegotiation.
+
+=head1 NOTES
+
+The behaviour of the SSL library can be changed by setting several options.
+The options are coded as bitmasks and can be combined by a logical B<or>
+operation (|).
+
+SSL_CTX_set_options() and SSL_set_options() affect the (external)
+protocol behaviour of the SSL library. The (internal) behaviour of
+the API can be changed by using the similar
+L<SSL_CTX_set_mode(3)|SSL_CTX_set_mode(3)> and SSL_set_mode() functions.
+
+During a handshake, the option settings of the SSL object are used. When
+a new SSL object is created from a context using SSL_new(), the current
+option setting is copied. Changes to B<ctx> do not affect already created
+SSL objects. SSL_clear() does not affect the settings.
+
+The following B<bug workaround> options are available:
+
+=over 4
+
+=item SSL_OP_MICROSOFT_SESS_ID_BUG
+
+www.microsoft.com - when talking SSLv2, if session-id reuse is
+performed, the session-id passed back in the server-finished message
+is different from the one decided upon.
+
+=item SSL_OP_NETSCAPE_CHALLENGE_BUG
+
+Netscape-Commerce/1.12, when talking SSLv2, accepts a 32 byte
+challenge but then appears to only use 16 bytes when generating the
+encryption keys.  Using 16 bytes is ok but it should be ok to use 32.
+According to the SSLv3 spec, one should use 32 bytes for the challenge
+when operating in SSLv2/v3 compatibility mode, but as mentioned above,
+this breaks this server so 16 bytes is the way to go.
+
+=item SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG
+
+As of OpenSSL 0.9.8q and 1.0.0c, this option has no effect.

+Don't prefer ECDHE-ECDSA ciphers when the client appears to be Safari on OS X.
+OS X 10.8..10.8.3 has broken support for ECDHE-ECDSA ciphers.

+
+Disables a countermeasure against a SSL 3.0/TLS 1.0 protocol
+vulnerability affecting CBC ciphers, which cannot be handled by some
+broken SSL implementations.  This option has no effect for connections
+using other ciphers.
+
+=item SSL_OP_TLSEXT_PADDING
+
+Adds a padding extension to ensure the ClientHello size is never between
+256 and 511 bytes in length. This is needed as a workaround for some
+implementations.
+
+=item SSL_OP_ALL
+
+All of the above bug workarounds.
+
+=back
+
+It is usually safe to use B<SSL_OP_ALL> to enable the bug workaround
+options if compatibility with somewhat broken implementations is
+desired.
+
+The following B<modifying> options are available:
+
+=over 4
+
+=item SSL_OP_TLS_ROLLBACK_BUG
+
+Disable version rollback attack detection.
+
+During the client key exchange, the client must send the same information
+about acceptable SSL/TLS protocol levels as during the first hello. Some
+clients violate this rule by adapting to the server's answer. (Example:
+the client sends a SSLv2 hello and accepts up to SSLv3.1=TLSv1, the server
+only understands up to SSLv3. In this case the client must still use the
+same SSLv3.1=TLSv1 announcement. Some clients step down to SSLv3 with respect
+to the server's answer and violate the version rollback protection.)
+
+=item SSL_OP_SINGLE_DH_USE
+
+Always create a new key when using temporary/ephemeral DH parameters
+(see L<SSL_CTX_set_tmp_dh_callback(3)|SSL_CTX_set_tmp_dh_callback(3)>).
+This option must be used to prevent small subgroup attacks, when
+the DH parameters were not generated using "strong" primes
+(e.g. when using DSA-parameters, see L<dhparam(1)|dhparam(1)>).
+If "strong" primes were used, it is not strictly necessary to generate
+a new DH key during each handshake but it is also recommended.
+B<SSL_OP_SINGLE_DH_USE> should therefore be enabled whenever
+temporary/ephemeral DH parameters are used.
+
+=item SSL_OP_EPHEMERAL_RSA
+
+This option is no longer implemented and is treated as no op.
+
+=item SSL_OP_CIPHER_SERVER_PREFERENCE
+
+When choosing a cipher, use the server's preferences instead of the client
+preferences. When not set, the SSL server will always follow the clients
+preferences. When set, the SSLv3/TLSv1 server will choose following its
+own preferences. Because of the different protocol, for SSLv2 the server
+will send its list of preferences to the client and the client chooses.
+
+=item SSL_OP_PKCS1_CHECK_1
+
+...
+
+=item SSL_OP_PKCS1_CHECK_2
+
+...
+
+=item SSL_OP_NETSCAPE_CA_DN_BUG
+
+If we accept a netscape connection, demand a client cert, have a
+non-self-signed CA which does not have its CA in netscape, and the
+browser has a cert, it will crash/hang.  Works for 3.x and 4.xbeta 
+
+=item SSL_OP_NETSCAPE_DEMO_CIPHER_CHANGE_BUG
+
+...
+
+=item SSL_OP_NO_SSLv2
+
+Do not use the SSLv2 protocol.
+As of OpenSSL 1.0.2g the B<SSL_OP_NO_SSLv2> option is set by default.
+
+=item SSL_OP_NO_SSLv3
+
+Do not use the SSLv3 protocol.
+It is recommended that applications should set this option.
+
+=item SSL_OP_NO_TLSv1
+
+Do not use the TLSv1 protocol.
+
+=item SSL_OP_NO_TLSv1_1
+
+Do not use the TLSv1.1 protocol.
+
+=item SSL_OP_NO_TLSv1_2
+
+Do not use the TLSv1.2 protocol.
+
+=item SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION
+
+When performing renegotiation as a server, always start a new session
+(i.e., session resumption requests are only accepted in the initial
+handshake). This option is not needed for clients.
+
+=item SSL_OP_NO_TICKET
+
+Normally clients and servers will, where possible, transparently make use
+of RFC4507bis tickets for stateless session resumption.
+
+If this option is set this functionality is disabled and tickets will
+not be used by clients or servers.
+
+=item SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION
+
+Allow legacy insecure renegotiation between OpenSSL and unpatched clients or
+servers. See the B<SECURE RENEGOTIATION> section for more details.
+
+=item SSL_OP_LEGACY_SERVER_CONNECT
+
+Allow legacy insecure renegotiation between OpenSSL and unpatched servers
+B<only>: this option is currently set by default. See the
+B<SECURE RENEGOTIATION> section for more details.
+
+=back
+
+=head1 SECURE RENEGOTIATION
+
+OpenSSL 0.9.8m and later always attempts to use secure renegotiation as
+described in RFC5746. This counters the prefix attack described in
+CVE-2009-3555 and elsewhere.
+
+The deprecated and highly broken SSLv2 protocol does not support
+renegotiation at all: its use is B<strongly> discouraged.
+
+This attack has far reaching consequences which application writers should be
+aware of. In the description below an implementation supporting secure
+renegotiation is referred to as I<patched>. A server not supporting secure
+renegotiation is referred to as I<unpatched>.
+
+The following sections describe the operations permitted by OpenSSL's secure
+renegotiation implementation.
+
+=head2 Patched client and server
+
+Connections and renegotiation are always permitted by OpenSSL implementations.
+
+=head2 Unpatched client and patched OpenSSL server
+
+The initial connection succeeds but client renegotiation is denied by the
+server with a B<no_renegotiation> warning alert if TLS v1.0 is used or a fatal
+B<handshake_failure> alert in SSL v3.0.
+
+If the patched OpenSSL server attempts to renegotiate a fatal
+B<handshake_failure> alert is sent. This is because the server code may be
+unaware of the unpatched nature of the client.
+
+If the option B<SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION> is set then
+renegotiation B<always> succeeds.
+
+B<NB:> a bug in OpenSSL clients earlier than 0.9.8m (all of which are
+unpatched) will result in the connection hanging if it receives a
+B<no_renegotiation> alert. OpenSSL versions 0.9.8m and later will regard
+a B<no_renegotiation> alert as fatal and respond with a fatal
+B<handshake_failure> alert. This is because the OpenSSL API currently has
+no provision to indicate to an application that a renegotiation attempt
+was refused.
+
+=head2 Patched OpenSSL client and unpatched server.
+
+If the option B<SSL_OP_LEGACY_SERVER_CONNECT> or
+B<SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION> is set then initial connections
+and renegotiation between patched OpenSSL clients and unpatched servers
+succeeds. If neither option is set then initial connections to unpatched
+servers will fail.
+
+The option B<SSL_OP_LEGACY_SERVER_CONNECT> is currently set by default even
+though it has security implications: otherwise it would be impossible to
+connect to unpatched servers (i.e. all of them initially) and this is clearly
+not acceptable. Renegotiation is permitted because this does not add any
+additional security issues: during an attack clients do not see any
+renegotiations anyway.
+
+As more servers become patched the option B<SSL_OP_LEGACY_SERVER_CONNECT> will
+B<not> be set by default in a future version of OpenSSL.
+
+OpenSSL client applications wishing to ensure they can connect to unpatched
+servers should always B<set> B<SSL_OP_LEGACY_SERVER_CONNECT>
+
+OpenSSL client applications that want to ensure they can B<not> connect to
+unpatched servers (and thus avoid any security issues) should always B<clear>
+B<SSL_OP_LEGACY_SERVER_CONNECT> using SSL_CTX_clear_options() or
+SSL_clear_options().
+
+The difference between the B<SSL_OP_LEGACY_SERVER_CONNECT> and
+B<SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION> options is that
+B<SSL_OP_LEGACY_SERVER_CONNECT> enables initial connections and secure
+renegotiation between OpenSSL clients and unpatched servers B<only>, while
+B<SSL_OP_ALLOW_UNSAFE_LEGACY_RENEGOTIATION> allows initial connections
+and renegotiation between OpenSSL and unpatched clients or servers.
+

+
+SSL_CTX_set_options() and SSL_set_options() return the new options bitmask

+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ void SSL_CTX_set_psk_client_callback(SSL_CTX *ctx,
+	unsigned int (*callback)(SSL *ssl, const char *hint,
+	char *identity, unsigned int max_identity_len,
+	unsigned char *psk, unsigned int max_psk_len));
+ void SSL_set_psk_client_callback(SSL *ssl,
+	unsigned int (*callback)(SSL *ssl, const char *hint,
+	char *identity, unsigned int max_identity_len,
+ 	unsigned char *psk, unsigned int max_psk_len));
+
+
+=head1 DESCRIPTION
+
+A client application must provide a callback function which is called
+when the client is sending the ClientKeyExchange message to the server.
+
+The purpose of the callback function is to select the PSK identity and
+the pre-shared key to use during the connection setup phase.
+
+The callback is set using functions SSL_CTX_set_psk_client_callback()
+or SSL_set_psk_client_callback(). The callback function is given the
+connection in parameter B<ssl>, a B<NULL>-terminated PSK identity hint
+sent by the server in parameter B<hint>, a buffer B<identity> of
+length B<max_identity_len> bytes where the the resulting
+B<NULL>-terminated identity is to be stored, and a buffer B<psk> of
+length B<max_psk_len> bytes where the resulting pre-shared key is to
+be stored.
+
+=head1 NOTES
+
+Note that parameter B<hint> given to the callback may be B<NULL>.

+
+=head1 DESCRIPTION
+
+SSL_CTX_set_quiet_shutdown() sets the "quiet shutdown" flag for B<ctx> to be
+B<mode>. SSL objects created from B<ctx> inherit the B<mode> valid at the time
+L<SSL_new(3)|SSL_new(3)> is called. B<mode> may be 0 or 1.
+
+SSL_CTX_get_quiet_shutdown() returns the "quiet shutdown" setting of B<ctx>.
+
+SSL_set_quiet_shutdown() sets the "quiet shutdown" flag for B<ssl> to be
+B<mode>. The setting stays valid until B<ssl> is removed with
+L<SSL_free(3)|SSL_free(3)> or SSL_set_quiet_shutdown() is called again.
+It is not changed when L<SSL_clear(3)|SSL_clear(3)> is called.
+B<mode> may be 0 or 1.
+
+SSL_get_quiet_shutdown() returns the "quiet shutdown" setting of B<ssl>.
+
+=head1 NOTES
+
+Normally when a SSL connection is finished, the parties must send out
+"close notify" alert messages using L<SSL_shutdown(3)|SSL_shutdown(3)>
+for a clean shutdown.
+
+When setting the "quiet shutdown" flag to 1, L<SSL_shutdown(3)|SSL_shutdown(3)>
+will set the internal flags to SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN.
+(L<SSL_shutdown(3)|SSL_shutdown(3)> then behaves like
+L<SSL_set_shutdown(3)|SSL_set_shutdown(3)> called with
+SSL_SENT_SHUTDOWN|SSL_RECEIVED_SHUTDOWN.)
+The session is thus considered to be shutdown, but no "close notify" alert
+is sent to the peer. This behaviour violates the TLS standard.
+
+The default is normal shutdown behaviour as described by the TLS standard.

+
+SSL_CTX_set_read_ahead() and SSL_set_read_ahead() set whether we should read as
+many input bytes as possible (for non-blocking reads) or not. For example if
+B<x> bytes are currently required by OpenSSL, but B<y> bytes are available from

+into its buffer (providing that the buffer is large enough) if reading ahead is
+on, or B<x> bytes otherwise. The parameter B<yes> or B<m> should be 0 to ensure
+reading ahead is off, or non zero otherwise.
+
+SSL_CTX_set_default_read_ahead is a synonym for SSL_CTX_set_read_ahead, and
+SSL_CTX_get_default_read_ahead is a synonym for SSL_CTX_get_read_ahead.

+
+ long SSL_CTX_set_session_cache_mode(SSL_CTX ctx, long mode);
+ long SSL_CTX_get_session_cache_mode(SSL_CTX ctx);
+
+=head1 DESCRIPTION
+
+SSL_CTX_set_session_cache_mode() enables/disables session caching
+by setting the operational mode for B<ctx> to <mode>.
+
+SSL_CTX_get_session_cache_mode() returns the currently used cache mode.
+
+=head1 NOTES
+
+The OpenSSL library can store/retrieve SSL/TLS sessions for later reuse.
+The sessions can be held in memory for each B<ctx>, if more than one
+SSL_CTX object is being maintained, the sessions are unique for each SSL_CTX
+object.
+
+In order to reuse a session, a client must send the session's id to the
+server. It can only send exactly one id.  The server then either 
+agrees to reuse the session or it starts a full handshake (to create a new
+session).
+
+A server will look up the session in its internal session storage. If the
+session is not found in internal storage or lookups for the internal storage
+have been deactivated (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP), the server will try
+the external storage if available.
+
+Since a client may try to reuse a session intended for use in a different
+context, the session id context must be set by the server (see
+L<SSL_CTX_set_session_id_context(3)|SSL_CTX_set_session_id_context(3)>).
+
+The following session cache modes and modifiers are available:
+
+=over 4
+
+=item SSL_SESS_CACHE_OFF
+
+No session caching for client or server takes place.
+
+=item SSL_SESS_CACHE_CLIENT
+
+Client sessions are added to the session cache. As there is no reliable way
+for the OpenSSL library to know whether a session should be reused or which
+session to choose (due to the abstract BIO layer the SSL engine does not
+have details about the connection), the application must select the session
+to be reused by using the L<SSL_set_session(3)|SSL_set_session(3)>
+function. This option is not activated by default.
+
+=item SSL_SESS_CACHE_SERVER
+
+Server sessions are added to the session cache. When a client proposes a
+session to be reused, the server looks for the corresponding session in (first)
+the internal session cache (unless SSL_SESS_CACHE_NO_INTERNAL_LOOKUP is set),
+then (second) in the external cache if available. If the session is found, the
+server will try to reuse the session.  This is the default.
+
+=item SSL_SESS_CACHE_BOTH
+
+Enable both SSL_SESS_CACHE_CLIENT and SSL_SESS_CACHE_SERVER at the same time.
+
+=item SSL_SESS_CACHE_NO_AUTO_CLEAR
+
+Normally the session cache is checked for expired sessions every
+255 connections using the
+L<SSL_CTX_flush_sessions(3)|SSL_CTX_flush_sessions(3)> function. Since
+this may lead to a delay which cannot be controlled, the automatic
+flushing may be disabled and
+L<SSL_CTX_flush_sessions(3)|SSL_CTX_flush_sessions(3)> can be called
+explicitly by the application.
+
+=item SSL_SESS_CACHE_NO_INTERNAL_LOOKUP
+
+By setting this flag, session-resume operations in an SSL/TLS server will not
+automatically look up sessions in the internal cache, even if sessions are
+automatically stored there. If external session caching callbacks are in use,
+this flag guarantees that all lookups are directed to the external cache.
+As automatic lookup only applies for SSL/TLS servers, the flag has no effect on
+clients.
+
+=item SSL_SESS_CACHE_NO_INTERNAL_STORE
+
+Depending on the presence of SSL_SESS_CACHE_CLIENT and/or SSL_SESS_CACHE_SERVER,
+sessions negotiated in an SSL/TLS handshake may be cached for possible reuse.
+Normally a new session is added to the internal cache as well as any external
+session caching (callback) that is configured for the SSL_CTX. This flag will
+prevent sessions being stored in the internal cache (though the application can
+add them manually using L<SSL_CTX_add_session(3)|SSL_CTX_add_session(3)>). Note:
+in any SSL/TLS servers where external caching is configured, any successful
+session lookups in the external cache (ie. for session-resume requests) would
+normally be copied into the local cache before processing continues - this flag
+prevents these additions to the internal cache as well.
+
+=item SSL_SESS_CACHE_NO_INTERNAL
+
+Enable both SSL_SESS_CACHE_NO_INTERNAL_LOOKUP and
+SSL_SESS_CACHE_NO_INTERNAL_STORE at the same time.

+
+ int SSL_CTX_set_session_id_context(SSL_CTX *ctx, const unsigned char *sid_ctx,

+
+=head1 DESCRIPTION
+
+SSL_CTX_set_session_id_context() sets the context B<sid_ctx> of length
+B<sid_ctx_len> within which a session can be reused for the B<ctx> object.
+
+SSL_set_session_id_context() sets the context B<sid_ctx> of length
+B<sid_ctx_len> within which a session can be reused for the B<ssl> object.
+
+=head1 NOTES
+
+Sessions are generated within a certain context. When exporting/importing
+sessions with B<i2d_SSL_SESSION>/B<d2i_SSL_SESSION> it would be possible,
+to re-import a session generated from another context (e.g. another
+application), which might lead to malfunctions. Therefore each application
+must set its own session id context B<sid_ctx> which is used to distinguish
+the contexts and is stored in exported sessions. The B<sid_ctx> can be
+any kind of binary data with a given length, it is therefore possible
+to use e.g. the name of the application and/or the hostname and/or service
+name ...
+
+The session id context becomes part of the session. The session id context
+is set by the SSL/TLS server. The SSL_CTX_set_session_id_context() and
+SSL_set_session_id_context() functions are therefore only useful on the
+server side.
+
+OpenSSL clients will check the session id context returned by the server
+when reusing a session.
+
+The maximum length of the B<sid_ctx> is limited to
+B<SSL_MAX_SSL_SESSION_ID_LENGTH>.
+
+=head1 WARNINGS
+
+If the session id context is not set on an SSL/TLS server and client
+certificates are used, stored sessions
+will not be reused but a fatal error will be flagged and the handshake
+will fail.
+
+If a server returns a different session id context to an OpenSSL client
+when reusing a session, an error will be flagged and the handshake will
+fail. OpenSSL servers will always return the correct session id context,
+as an OpenSSL server checks the session id context itself before reusing
+a session as described above.

+Whenever a new session is created, it is assigned a maximum lifetime. This

+Due to this realization, all sessions behave according to the timeout value
+valid at the time of the session negotiation. Changes of the timeout value

+
+=head1 DESCRIPTION
+
+A client application may request that a server send back an OCSP status response
+(also known as OCSP stapling). To do so the client should call the
+SSL_set_tlsext_status_type() function prior to the start of the handshake.
+Currently the only supported type is B<TLSEXT_STATUSTYPE_ocsp>. This value
+should be passed in the B<type> argument. The client should additionally provide
+a callback function to decide what to do with the returned OCSP response by
+calling SSL_CTX_set_tlsext_status_cb(). The callback function should determine
+whether the returned OCSP response is acceptable or not. The callback will be
+passed as an argument the value previously set via a call to
+SSL_CTX_set_tlsext_status_arg(). Note that the callback will not be called in
+the event of a handshake where session resumption occurs (because there are no
+Certificates exchanged in such a handshake).
+
+The response returned by the server can be obtained via a call to
+SSL_get_tlsext_status_ocsp_resp(). The value B<*resp> will be updated to point
+to the OCSP response data and the return value will be the length of that data.
+Typically a callback would obtain an OCSP_RESPONSE object from this data via a
+call to the d2i_OCSP_RESPONSE() function. If the server has not provided any
+response data then B<*resp> will be NULL and the return value from
+SSL_get_tlsext_status_ocsp_resp() will be -1.
+
+A server application must also call the SSL_CTX_set_tlsext_status_cb() function
+if it wants to be able to provide clients with OCSP Certificate Status
+responses. Typically the server callback would obtain the server certificate
+that is being sent back to the client via a call to SSL_get_certificate();
+obtain the OCSP response to be sent back; and then set that response data by
+calling SSL_set_tlsext_status_ocsp_resp(). A pointer to the response data should
+be provided in the B<resp> argument, and the length of that data should be in
+the B<len> argument.
+
+=head1 RETURN VALUES
+
+The callback when used on the client side should return a negative value on
+error; 0 if the response is not acceptable (in which case the handshake will
+fail) or a positive value if it is acceptable.
+
+The callback when used on the server side should return with either
+SSL_TLSEXT_ERR_OK (meaning that the OCSP response that has been set should be
+returned), SSL_TLSEXT_ERR_NOACK (meaning that an OCSP response should not be
+returned) or SSL_TLSEXT_ERR_ALERT_FATAL (meaning that a fatal error has

+SSL_CTX_set_tlsext_ticket_key_cb() sets a callback fuction I<cb> for handling

+The callback function I<cb> will be called for every client instigated TLS
+session when session ticket extension is presented in the TLS hello
+message. It is the responsibility of this function to create or retrieve the
+cryptographic parameters and to maintain their state.
+
+The OpenSSL library uses your callback function to help implement a common TLS 
+ticket construction state according to RFC5077 Section 4 such that per session
+state is unnecessary and a small set of cryptographic variables needs to be 
+maintained by the callback function implementation.
+
+In order to reuse a session, a TLS client must send the a session ticket
+extension to the server. The client can only send exactly one session ticket.
+The server, through the callback function, either agrees to reuse the session
+ticket information or it starts a full TLS handshake to create a new session
+ticket.
+
+Before the callback function is started I<ctx> and I<hctx> have been 
+initialised with EVP_CIPHER_CTX_init and HMAC_CTX_init respectively.
+
+For new sessions tickets, when the client doesn't present a session ticket, or
+an attempted retreival of the ticket failed, or a renew option was indicated,
+the callback function will be called with I<enc> equal to 1. The OpenSSL
+library expects that the function will set an arbitary I<name>, initialize
+I<iv>, and set the cipher context I<ctx> and the hash context I<hctx>.
+
+The I<name> is 16 characters long and is used as a key identifier.
+
+The I<iv> length is the length of the IV of the corresponding cipher. The
+maximum IV length is L<EVP_MAX_IV_LENGTH> bytes defined in B<evp.h>.
+
+The initialization vector I<iv> should be a random value. The cipher context 
+I<ctx> should use the initialisation vector I<iv>. The cipher context can be 
+set using L<EVP_EncryptInit_ex>. The hmac context can be set using L<HMAC_Init_ex>.
+
+When the client presents a session ticket, the callback function with be called 
+with I<enc> set to 0 indicating that the I<cb> function should retreive a set
+of parameters. In this case I<name> and I<iv> have already been parsed out of
+the session ticket. The OpenSSL library expects that the I<name> will be used
+to retrieve a cryptographic parameters and that the cryptographic context
+I<ctx> will be set with the retreived parameters and the initialization vector
+I<iv>. using a function like L<EVP_DecryptInit_ex>. The I<hctx> needs to be set
+using L<HMAC_Init_ex>.
+
+If the I<name> is still valid but a renewal of the ticket is required the
+callback function should return 2. The library will call the callback again
+with an arguement of enc equal to 1 to set the new ticket.
+
+The return value of the I<cb> function is used by OpenSSL to determine what
+further processing will occur. The following return values have meaning:
+
+=over 4
+
+=item Z<>2
+
+This indicates that the I<ctx> and I<hctx> have been set and the session can 
+continue on those parameters. Additionally it indicates that the session
+ticket is in a renewal period and should be replaced. The OpenSSL library will
+call I<cb> again with an enc argument of 1 to set the new ticket (see RFC5077
+3.3 paragraph 2).
+
+=item Z<>1
+
+This indicates that the I<ctx> and I<hctx> have been set and the session can 
+continue on those parameters.
+
+=item Z<>0
+
+This indicates that it was not possible to set/retrieve a session ticket and 
+the SSL/TLS session will continue by by negiotationing a set of cryptographic
+parameters or using the alternate SSL/TLS resumption mechanism, session ids.
+
+If called with enc equal to 0 the library will call the I<cb> again to get
+a new set of parameters.
+
+=item less than 0
+
+This indicates an error.
+
+=back
+
+=head1 NOTES
+
+Session resumption shortcuts the TLS so that the client certificate
+negiotation don't occur. It makes up for this by storing client certificate
+an all other negotiated state information encrypted within the ticket. In a
+resumed session the applications will have all this state information available
+exactly as if a full negiotation had occured.
+
+If an attacker can obtain the key used to encrypt a session ticket, they can
+obtain the master secret for any ticket using that key and decrypt any traffic
+using that session: even if the ciphersuite supports forward secrecy. As
+a result applications may wish to use multiple keys and avoid using long term
+keys stored in files.
+
+Applications can use longer keys to maintain a consistent level of security.
+For example if a ciphersuite uses 256 bit ciphers but only a 128 bit ticket key
+the overall security is only 128 bits because breaking the ticket key will
+enable an attacker to obtain the session keys.

+
+SSL_CTX_set_tmp_dh_callback() sets the callback function for B<ctx> to be

+The callback is inherited by all B<ssl> objects created from B<ctx>.

+

+
+SSL_set_tmp_dh() sets the parameters only for B<ssl>.
+
+These functions apply to SSL/TLS servers only.
+
+=head1 NOTES
+
+When using a cipher with RSA authentication, an ephemeral DH key exchange
+can take place. Ciphers with DSA keys always use ephemeral DH keys as well.
+In these cases, the session data are negotiated using the
+ephemeral/temporary DH key and the key supplied and certified
+by the certificate chain is only used for signing.
+Anonymous ciphers (without a permanent server key) also use ephemeral DH keys.
+
+Using ephemeral DH key exchange yields forward secrecy, as the connection
+can only be decrypted, when the DH key is known. By generating a temporary
+DH key inside the server application that is lost when the application
+is left, it becomes impossible for an attacker to decrypt past sessions,
+even if he gets hold of the normal (certified) key, as this key was
+only used for signing.
+
+In order to perform a DH key exchange the server must use a DH group
+(DH parameters) and generate a DH key. The server will always generate
+a new DH key during the negotiation.
+
+As generating DH parameters is extremely time consuming, an application
+should not generate the parameters on the fly but supply the parameters.
+DH parameters can be reused, as the actual key is newly generated during
+the negotiation. The risk in reusing DH parameters is that an attacker
+may specialize on a very often used DH group. Applications should therefore
+generate their own DH parameters during the installation process using the
+openssl L<dhparam(1)|dhparam(1)> application. This application
+guarantees that "strong" primes are used.
+
+Files dh2048.pem, and dh4096.pem in the 'apps' directory of the current
+version of the OpenSSL distribution contain the 'SKIP' DH parameters,
+which use safe primes and were generated verifiably pseudo-randomly.
+These files can be converted into C code using the B<-C> option of the
+L<dhparam(1)|dhparam(1)> application. Generation of custom DH
+parameters during installation should still be preferred to stop an
+attacker from specializing on a commonly used group. Files dh1024.pem
+and dh512.pem contain old parameters that must not be used by
+applications.
+
+An application may either directly specify the DH parameters or
+can supply the DH parameters via a callback function.
+
+Previous versions of the callback used B<is_export> and B<keylength>
+parameters to control parameter generation for export and non-export
+cipher suites. Modern servers that do not support export ciphersuites
+are advised to either use SSL_CTX_set_tmp_dh() or alternatively, use
+the callback but ignore B<keylength> and B<is_export> and simply
+supply at least 2048-bit parameters in the callback.
+

+
+SSL_need_tmp_rsa() returns 1, if a temporary/ephemeral RSA key is needed,
+for RSA-based strength-limited 'exportable' ciphersuites because a RSA key
+with a keysize larger than 512 bits is installed.
+
+These functions apply to SSL/TLS servers only.
+
+=head1 NOTES
+
+When using a cipher with RSA authentication, an ephemeral RSA key exchange
+can take place. In this case the session data are negotiated using the
+ephemeral/temporary RSA key and the RSA key supplied and certified
+by the certificate chain is only used for signing.
+
+Under previous export restrictions, ciphers with RSA keys shorter (512 bits)
+than the usual key length of 1024 bits were created. To use these ciphers
+with RSA keys of usual length, an ephemeral key exchange must be performed,
+as the normal (certified) key cannot be directly used.
+
+Using ephemeral RSA key exchange yields forward secrecy, as the connection
+can only be decrypted, when the RSA key is known. By generating a temporary
+RSA key inside the server application that is lost when the application
+is left, it becomes impossible for an attacker to decrypt past sessions,
+even if he gets hold of the normal (certified) RSA key, as this key was
+used for signing only. The downside is that creating a RSA key is
+computationally expensive.
+
+Additionally, the use of ephemeral RSA key exchange is only allowed in
+the TLS standard, when the RSA key can be used for signing only, that is
+for export ciphers. Using ephemeral RSA key exchange for other purposes
+violates the standard and can break interoperability with clients.
+It is therefore strongly recommended to not use ephemeral RSA key
+exchange and use DHE (Ephemeral Diffie-Hellman) key exchange instead
+in order to achieve forward secrecy (see
+L<SSL_CTX_set_tmp_dh_callback(3)|SSL_CTX_set_tmp_dh_callback(3)>).
+
+An application may either directly specify the key or can supply the key via a
+callback function. The callback approach has the advantage, that the callback
+may generate the key only in case it is actually needed. As the generation of a
+RSA key is however costly, it will lead to a significant delay in the handshake
+procedure.  Another advantage of the callback function is that it can supply
+keys of different size while the explicit setting of the key is only useful for
+key size of 512 bits to satisfy the export restricted ciphers and does give
+away key length if a longer key would be allowed.
+
+The B<tmp_rsa_callback> is called with the B<keylength> needed and
+the B<is_export> information. The B<is_export> flag is set, when the
+ephemeral RSA key exchange is performed with an export cipher.
+
+=head1 EXAMPLES
+
+Generate temporary RSA keys to prepare ephemeral RSA key exchange. As the
+generation of a RSA key costs a lot of computer time, they saved for later
+reuse. For demonstration purposes, two keys for 512 bits and 1024 bits
+respectively are generated.

+=head1 NOTES
+
+The verification of certificates can be controlled by a set of logically
+or'ed B<mode> flags:
+
+=over 4
+
+=item SSL_VERIFY_NONE
+
+B<Server mode:> the server will not send a client certificate request to the
+client, so the client will not send a certificate.
+
+B<Client mode:> if not using an anonymous cipher (by default disabled), the
+server will send a certificate which will be checked. The result of the
+certificate verification process can be checked after the TLS/SSL handshake
+using the L<SSL_get_verify_result(3)|SSL_get_verify_result(3)> function.
+The handshake will be continued regardless of the verification result.
+
+=item SSL_VERIFY_PEER
+
+B<Server mode:> the server sends a client certificate request to the client.
+The certificate returned (if any) is checked. If the verification process
+fails, the TLS/SSL handshake is
+immediately terminated with an alert message containing the reason for
+the verification failure.
+The behaviour can be controlled by the additional
+SSL_VERIFY_FAIL_IF_NO_PEER_CERT and SSL_VERIFY_CLIENT_ONCE flags.
+
+B<Client mode:> the server certificate is verified. If the verification process
+fails, the TLS/SSL handshake is
+immediately terminated with an alert message containing the reason for
+the verification failure. If no server certificate is sent, because an
+anonymous cipher is used, SSL_VERIFY_PEER is ignored.
+
+=item SSL_VERIFY_FAIL_IF_NO_PEER_CERT
+
+B<Server mode:> if the client did not return a certificate, the TLS/SSL
+handshake is immediately terminated with a "handshake failure" alert.
+This flag must be used together with SSL_VERIFY_PEER.
+
+B<Client mode:> ignored
+
+=item SSL_VERIFY_CLIENT_ONCE
+
+B<Server mode:> only request a client certificate on the initial TLS/SSL
+handshake. Do not ask for a client certificate again in case of a
+renegotiation. This flag must be used together with SSL_VERIFY_PEER.
+
+B<Client mode:> ignored
+
+=back
+
+Exactly one of the B<mode> flags SSL_VERIFY_NONE and SSL_VERIFY_PEER must be
+set at any time.
+
+The actual verification procedure is performed either using the built-in
+verification procedure or using another application provided verification
+function set with
+L<SSL_CTX_set_cert_verify_callback(3)|SSL_CTX_set_cert_verify_callback(3)>.
+The following descriptions apply in the case of the built-in procedure. An
+application provided procedure also has access to the verify depth information
+and the verify_callback() function, but the way this information is used
+may be different.
+
+SSL_CTX_set_verify_depth() and SSL_set_verify_depth() set the limit up
+to which depth certificates in a chain are used during the verification
+procedure. If the certificate chain is longer than allowed, the certificates
+above the limit are ignored. Error messages are generated as if these
+certificates would not be present, most likely a
+X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY will be issued.
+The depth count is "level 0:peer certificate", "level 1: CA certificate",
+"level 2: higher level CA certificate", and so on. Setting the maximum
+depth to 2 allows the levels 0, 1, and 2. The default depth limit is 100,
+allowing for the peer certificate and additional 100 CA certificates.
+
+The B<verify_callback> function is used to control the behaviour when the
+SSL_VERIFY_PEER flag is set. It must be supplied by the application and
+receives two arguments: B<preverify_ok> indicates, whether the verification of
+the certificate in question was passed (preverify_ok=1) or not
+(preverify_ok=0). B<x509_ctx> is a pointer to the complete context used
+for the certificate chain verification.
+
+The certificate chain is checked starting with the deepest nesting level
+(the root CA certificate) and worked upward to the peer's certificate.
+At each level signatures and issuer attributes are checked. Whenever
+a verification error is found, the error number is stored in B<x509_ctx>
+and B<verify_callback> is called with B<preverify_ok>=0. By applying
+X509_CTX_store_* functions B<verify_callback> can locate the certificate
+in question and perform additional steps (see EXAMPLES). If no error is
+found for a certificate, B<verify_callback> is called with B<preverify_ok>=1
+before advancing to the next level.
+
+The return value of B<verify_callback> controls the strategy of the further
+verification process. If B<verify_callback> returns 0, the verification
+process is immediately stopped with "verification failed" state. If
+SSL_VERIFY_PEER is set, a verification failure alert is sent to the peer and
+the TLS/SSL handshake is terminated. If B<verify_callback> returns 1,
+the verification process is continued. If B<verify_callback> always returns
+1, the TLS/SSL handshake will not be terminated with respect to verification
+failures and the connection will be established. The calling process can
+however retrieve the error code of the last verification error using
+L<SSL_get_verify_result(3)|SSL_get_verify_result(3)> or by maintaining its
+own error storage managed by B<verify_callback>.
+
+If no B<verify_callback> is specified, the default callback will be used.
+Its return value is identical to B<preverify_ok>, so that any verification
+failure will lead to a termination of the TLS/SSL handshake with an
+alert message, if SSL_VERIFY_PEER is set.
+
+=head1 BUGS
+
+In client mode, it is not checked whether the SSL_VERIFY_PEER flag
+is set, but whether SSL_VERIFY_NONE is not set. This can lead to
+unexpected behaviour, if the SSL_VERIFY_PEER and SSL_VERIFY_NONE are not
+used as required (exactly one must be set at any time).
+
+The certificate verification depth set with SSL[_CTX]_verify_depth()
+stops the verification at a certain depth. The error message produced
+will be that of an incomplete certificate chain and not
+X509_V_ERR_CERT_CHAIN_TOO_LONG as may be expected.
+
+=head1 RETURN VALUES
+
+The SSL*_set_verify*() functions do not provide diagnostic information.
+
+=head1 EXAMPLES
+
+The following code sequence realizes an example B<verify_callback> function
+that will always continue the TLS/SSL handshake regardless of verification
+failure, if wished. The callback realizes a verification depth limit with
+more informational output.
+
+All verification errors are printed; information about the certificate chain
+is printed on request.
+The example is realized for a server that does allow but not require client
+certificates.
+
+The example makes use of the ex_data technique to store application data
+into/retrieve application data from the SSL structure
+(see L<SSL_get_ex_new_index(3)|SSL_get_ex_new_index(3)>,
+L<SSL_get_ex_data_X509_STORE_CTX_idx(3)|SSL_get_ex_data_X509_STORE_CTX_idx(3)>).

+=head1 DESCRIPTION
+
+These functions load the certificates and private keys into the SSL_CTX
+or SSL object, respectively.
+
+The SSL_CTX_* class of functions loads the certificates and keys into the
+SSL_CTX object B<ctx>. The information is passed to SSL objects B<ssl>
+created from B<ctx> with L<SSL_new(3)|SSL_new(3)> by copying, so that
+changes applied to B<ctx> do not propagate to already existing SSL objects.
+
+The SSL_* class of functions only loads certificates and keys into a
+specific SSL object. The specific information is kept, when
+L<SSL_clear(3)|SSL_clear(3)> is called for this SSL object.
+
+SSL_CTX_use_certificate() loads the certificate B<x> into B<ctx>,
+SSL_use_certificate() loads B<x> into B<ssl>. The rest of the
+certificates needed to form the complete certificate chain can be
+specified using the
+L<SSL_CTX_add_extra_chain_cert(3)|SSL_CTX_add_extra_chain_cert(3)>
+function.
+
+SSL_CTX_use_certificate_ASN1() loads the ASN1 encoded certificate from
+the memory location B<d> (with length B<len>) into B<ctx>,
+SSL_use_certificate_ASN1() loads the ASN1 encoded certificate into B<ssl>.
+
+SSL_CTX_use_certificate_file() loads the first certificate stored in B<file>
+into B<ctx>. The formatting B<type> of the certificate must be specified
+from the known types SSL_FILETYPE_PEM, SSL_FILETYPE_ASN1.
+SSL_use_certificate_file() loads the certificate from B<file> into B<ssl>.
+See the NOTES section on why SSL_CTX_use_certificate_chain_file()
+should be preferred.
+
+SSL_CTX_use_certificate_chain_file() loads a certificate chain from 
+B<file> into B<ctx>. The certificates must be in PEM format and must
+be sorted starting with the subject's certificate (actual client or server
+certificate), followed by intermediate CA certificates if applicable, and
+ending at the highest level (root) CA.
+There is no corresponding function working on a single SSL object.
+
+SSL_CTX_use_PrivateKey() adds B<pkey> as private key to B<ctx>.
+SSL_CTX_use_RSAPrivateKey() adds the private key B<rsa> of type RSA
+to B<ctx>. SSL_use_PrivateKey() adds B<pkey> as private key to B<ssl>;
+SSL_use_RSAPrivateKey() adds B<rsa> as private key of type RSA to B<ssl>.
+If a certificate has already been set and the private does not belong
+to the certificate an error is returned. To change a certificate, private
+key pair the new certificate needs to be set with SSL_use_certificate()
+or SSL_CTX_use_certificate() before setting the private key with
+SSL_CTX_use_PrivateKey() or SSL_use_PrivateKey(). 
+
+
+SSL_CTX_use_PrivateKey_ASN1() adds the private key of type B<pk>
+stored at memory location B<d> (length B<len>) to B<ctx>.
+SSL_CTX_use_RSAPrivateKey_ASN1() adds the private key of type RSA
+stored at memory location B<d> (length B<len>) to B<ctx>.
+SSL_use_PrivateKey_ASN1() and SSL_use_RSAPrivateKey_ASN1() add the private
+key to B<ssl>.
+
+SSL_CTX_use_PrivateKey_file() adds the first private key found in
+B<file> to B<ctx>. The formatting B<type> of the certificate must be specified
+from the known types SSL_FILETYPE_PEM, SSL_FILETYPE_ASN1.
+SSL_CTX_use_RSAPrivateKey_file() adds the first private RSA key found in
+B<file> to B<ctx>. SSL_use_PrivateKey_file() adds the first private key found
+in B<file> to B<ssl>; SSL_use_RSAPrivateKey_file() adds the first private
+RSA key found to B<ssl>.
+
+SSL_CTX_check_private_key() checks the consistency of a private key with
+the corresponding certificate loaded into B<ctx>. If more than one
+key/certificate pair (RSA/DSA) is installed, the last item installed will
+be checked. If e.g. the last item was a RSA certificate or key, the RSA
+key/certificate pair will be checked. SSL_check_private_key() performs
+the same check for B<ssl>. If no key/certificate was explicitly added for
+this B<ssl>, the last item added into B<ctx> will be checked.
+
+=head1 NOTES
+  
+The internal certificate store of OpenSSL can hold several private
+key/certificate pairs at a time. The certificate used depends on the
+cipher selected, see also L<SSL_CTX_set_cipher_list(3)|SSL_CTX_set_cipher_list(3)>.
+
+When reading certificates and private keys from file, files of type
+SSL_FILETYPE_ASN1 (also known as B<DER>, binary encoding) can only contain
+one certificate or private key, consequently 
+SSL_CTX_use_certificate_chain_file() is only applicable to PEM formatting.
+Files of type SSL_FILETYPE_PEM can contain more than one item.
+
+SSL_CTX_use_certificate_chain_file() adds the first certificate found
+in the file to the certificate store. The other certificates are added
+to the store of chain certificates using L<SSL_CTX_add1_chain_cert(3)|SSL_CTX_add1_chain_cert(3)>. Note: versions of OpenSSL before 1.0.2 only had a single
+certificate chain store for all certificate types, OpenSSL 1.0.2 and later
+have a separate chain store for each type. SSL_CTX_use_certificate_chain_file() 
+should be used instead of the SSL_CTX_use_certificate_file() function in order
+to allow the use of complete certificate chains even when no trusted CA
+storage is used or when the CA issuing the certificate shall not be added to
+the trusted CA storage.
+
+If additional certificates are needed to complete the chain during the
+TLS negotiation, CA certificates are additionally looked up in the
+locations of trusted CA certificates, see
+L<SSL_CTX_load_verify_locations(3)|SSL_CTX_load_verify_locations(3)>.
+
+The private keys loaded from file can be encrypted. In order to successfully
+load encrypted keys, a function returning the passphrase must have been
+supplied, see
+L<SSL_CTX_set_default_passwd_cb(3)|SSL_CTX_set_default_passwd_cb(3)>.
+(Certificate files might be encrypted as well from the technical point
+of view, it however does not make sense as the data in the certificate
+is considered public anyway.)
+
+=head1 RETURN VALUES
+
+On success, the functions return 1.
+Otherwise check out the error stack to find out the reason.

+=head1 DESCRIPTION
+
+SSL_CTX_use_psk_identity_hint() sets the given B<NULL>-terminated PSK
+identity hint B<hint> to SSL context object
+B<ctx>. SSL_use_psk_identity_hint() sets the given B<NULL>-terminated
+PSK identity hint B<hint> to SSL connection object B<ssl>. If B<hint>
+is B<NULL> the current hint from B<ctx> or B<ssl> is deleted.
+
+In the case where PSK identity hint is B<NULL>, the server
+does not send the ServerKeyExchange message to the client.
+
+A server application must provide a callback function which is called
+when the server receives the ClientKeyExchange message from the
+client. The purpose of the callback function is to validate the
+received PSK identity and to fetch the pre-shared key used during the
+connection setup phase. The callback is set using functions
+SSL_CTX_set_psk_server_callback() or
+SSL_set_psk_server_callback(). The callback function is given the
+connection in parameter B<ssl>, B<NULL>-terminated PSK identity sent
+by the client in parameter B<identity>, and a buffer B<psk> of length
+B<max_psk_len> bytes where the pre-shared key is to be stored.
+
+
+=head1 RETURN VALUES
+
+SSL_CTX_use_psk_identity_hint() and SSL_use_psk_identity_hint() return
+1 on success, 0 otherwise.
+
+Return values from the server callback are interpreted as follows:
+
+=over 4
+
+=item Z<>0
+
+PSK identity was not found. An "unknown_psk_identity" alert message
+will be sent and the connection setup fails.
+
+=item E<gt>0
+
+PSK identity was found and the server callback has provided the PSK
+successfully in parameter B<psk>. Return value is the length of
+B<psk> in bytes. It is an error to return a value greater than
+B<max_psk_len>.
+
+If the PSK identity was not found but the callback instructs the
+protocol to continue anyway, the callback must provide some random
+data to B<psk> and return the length of the random data, so the
+connection will fail with decryption_error before it will be finished
+completely.

+
+=head1 DESCRIPTION
+
+These functions load "serverinfo" TLS ServerHello Extensions into the SSL_CTX.
+A "serverinfo" extension is returned in response to an empty ClientHello
+Extension.
+
+SSL_CTX_use_serverinfo() loads one or more serverinfo extensions from
+a byte array into B<ctx>.  The extensions must be concatenated into a 
+sequence of bytes.  Each extension must consist of a 2-byte Extension Type, 
+a 2-byte length, and then length bytes of extension_data.
+
+SSL_CTX_use_serverinfo_file() loads one or more serverinfo extensions from
+B<file> into B<ctx>.  The extensions must be in PEM format.  Each extension
+must consist of a 2-byte Extension Type, a 2-byte length, and then length
+bytes of extension_data.  Each PEM extension name must begin with the phrase
+"BEGIN SERVERINFO FOR ".
+
+If more than one certificate (RSA/DSA) is installed using
+SSL_CTX_use_certificate(), the serverinfo extension will be loaded into the
+last certificate installed.  If e.g. the last item was a RSA certificate, the
+loaded serverinfo extension data will be loaded for that certificate.  To
+use the serverinfo extension for multiple certificates,
+SSL_CTX_use_serverinfo() needs to be called multiple times, once B<after>
+each time a certificate is loaded.

+
+SSL_SESSION_free - free an allocated SSL_SESSION structure
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ void SSL_SESSION_free(SSL_SESSION *session);
+
+=head1 DESCRIPTION
+
+SSL_SESSION_free() decrements the reference count of B<session> and removes
+the B<SSL_SESSION> structure pointed to by B<session> and frees up the allocated
+memory, if the reference count has reached 0.
+
+=head1 NOTES
+
+SSL_SESSION objects are allocated, when a TLS/SSL handshake operation
+is successfully completed. Depending on the settings, see
+L<SSL_CTX_set_session_cache_mode(3)|SSL_CTX_set_session_cache_mode(3)>,
+the SSL_SESSION objects are internally referenced by the SSL_CTX and
+linked into its session cache. SSL objects may be using the SSL_SESSION object;
+as a session may be reused, several SSL objects may be using one SSL_SESSION
+object at the same time. It is therefore crucial to keep the reference
+count (usage information) correct and not delete a SSL_SESSION object
+that is still used, as this may lead to program failures due to
+dangling pointers. These failures may also appear delayed, e.g.
+when an SSL_SESSION object was completely freed as the reference count
+incorrectly became 0, but it is still referenced in the internal
+session cache and the cache list is processed during a
+L<SSL_CTX_flush_sessions(3)|SSL_CTX_flush_sessions(3)> operation.
+
+SSL_SESSION_free() must only be called for SSL_SESSION objects, for
+which the reference count was explicitly incremented (e.g.
+by calling SSL_get1_session(), see L<SSL_get_session(3)|SSL_get_session(3)>)
+or when the SSL_SESSION object was generated outside a TLS handshake
+operation, e.g. by using L<d2i_SSL_SESSION(3)|d2i_SSL_SESSION(3)>.
+It must not be called on other SSL_SESSION objects, as this would cause
+incorrect reference counts and therefore program failures.

+=head1 DESCRIPTION
+
+Several OpenSSL structures can have application specific data attached to them.
+These functions are used internally by OpenSSL to manipulate application
+specific data attached to a specific structure.
+
+SSL_SESSION_get_ex_new_index() is used to register a new index for application
+specific data.
+
+SSL_SESSION_set_ex_data() is used to store application data at B<arg> for B<idx>
+into the B<session> object.
+
+SSL_SESSION_get_ex_data() is used to retrieve the information for B<idx> from
+B<session>.
+
+A detailed description for the B<*_get_ex_new_index()> functionality
+can be found in L<RSA_get_ex_new_index(3)|RSA_get_ex_new_index(3)>.
+The B<*_get_ex_data()> and B<*_set_ex_data()> functionality is described in
+L<CRYPTO_set_ex_data(3)|CRYPTO_set_ex_data(3)>.
+
+=head1 WARNINGS
+
+The application data is only maintained for sessions held in memory. The
+application data is not included when dumping the session with
+i2d_SSL_SESSION() (and all functions indirectly calling the dump functions
+like PEM_write_SSL_SESSION() and PEM_write_bio_SSL_SESSION()) and can
+therefore not be restored.

+
+=head1 DESCRIPTION
+
+SSL_SESSION_get_time() returns the time at which the session B<s> was

+compatible to the time delivered by the time() call.
+
+SSL_SESSION_set_time() replaces the creation time of the session B<s> with

+
+SSL_SESSION_get_timeout() returns the timeout value set for session B<s>
+in seconds.
+
+SSL_SESSION_set_timeout() sets the timeout value for session B<s> in seconds
+to B<tm>.
+
+The SSL_get_time(), SSL_set_time(), SSL_get_timeout(), and SSL_set_timeout()
+functions are synonyms for the SSL_SESSION_*() counterparts.
+
+=head1 NOTES
+
+Sessions are expired by examining the creation time and the timeout value.
+Both are set at creation time of the session to the actual time and the
+default timeout value at creation, respectively, as set by

+Using these functions it is possible to extend or shorten the lifetime
+of the session.

+SSL_accept - wait for a TLS/SSL client to initiate a TLS/SSL handshake
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ int SSL_accept(SSL *ssl);
+
+=head1 DESCRIPTION
+
+SSL_accept() waits for a TLS/SSL client to initiate the TLS/SSL handshake.
+The communication channel must already have been set and assigned to the
+B<ssl> by setting an underlying B<BIO>.
+
+=head1 NOTES
+
+The behaviour of SSL_accept() depends on the underlying BIO. 
+
+If the underlying BIO is B<blocking>, SSL_accept() will only return once the
+handshake has been finished or an error occurred.
+
+If the underlying BIO is B<non-blocking>, SSL_accept() will also return
+when the underlying BIO could not satisfy the needs of SSL_accept()
+to continue the handshake, indicating the problem by the return value -1.
+In this case a call to SSL_get_error() with the
+return value of SSL_accept() will yield B<SSL_ERROR_WANT_READ> or
+B<SSL_ERROR_WANT_WRITE>. The calling process then must repeat the call after
+taking appropriate action to satisfy the needs of SSL_accept().
+The action depends on the underlying BIO. When using a non-blocking socket,
+nothing is to be done, but select() can be used to check for the required
+condition. When using a buffering BIO, like a BIO pair, data must be written
+into or retrieved out of the BIO before being able to continue.
+
+=head1 RETURN VALUES
+
+The following return values can occur:

+
+The TLS/SSL handshake was not successful but was shut down controlled and

+=item Z<>1
+
+The TLS/SSL handshake was successfully completed, a TLS/SSL connection has been

+at the protocol level or a connection failure occurred. The shutdown was

+=head1 NOTES
+
+When one side of an SSL/TLS communication wants to inform the peer about
+a special situation, it sends an alert. The alert is sent as a special message
+and does not influence the normal data stream (unless its contents results
+in the communication being canceled).
+
+A warning alert is sent, when a non-fatal error condition occurs. The
+"close notify" alert is sent as a warning alert. Other examples for
+non-fatal errors are certificate errors ("certificate expired",
+"unsupported certificate"), for which a warning alert may be sent.
+(The sending party may however decide to send a fatal error.) The
+receiving side may cancel the connection on reception of a warning
+alert on it discretion.
+
+Several alert messages must be sent as fatal alert messages as specified
+by the TLS RFC. A fatal alert always leads to a connection abort.

+
+=item "BM"/"bad record mac"
+
+This alert is returned if a record is received with an incorrect
+MAC. This message is always fatal.
+
+=item "DF"/"decompression failure"
+
+The decompression function received improper input (e.g. data
+that would expand to excessive length). This message is always
+fatal.
+
+=item "HF"/"handshake failure"
+
+Reception of a handshake_failure alert message indicates that the
+sender was unable to negotiate an acceptable set of security
+parameters given the options available. This is a fatal error.
+
+=item "NC"/"no certificate"
+
+A client, that was asked to send a certificate, does not send a certificate
+(SSLv3 only).
+
+=item "BC"/"bad certificate"
+
+A certificate was corrupt, contained signatures that did not

+
+=item "UC"/"unsupported certificate"
+
+A certificate was of an unsupported type.

+
+A certificate was revoked by its signer.
+
+=item "CE"/"certificate expired"
+
+A certificate has expired or is not currently valid.
+
+=item "CU"/"certificate unknown"
+
+Some other (unspecified) issue arose in processing the
+certificate, rendering it unacceptable.
+
+=item "IP"/"illegal parameter"
+
+A field in the handshake was out of range or inconsistent with
+other fields. This is always fatal.
+
+=item "DC"/"decryption failed"
+
+A TLSCiphertext decrypted in an invalid way: either it wasn't an
+even multiple of the block length or its padding values, when
+checked, weren't correct. This message is always fatal.
+
+=item "RO"/"record overflow"
+
+A TLSCiphertext record was received which had a length more than
+2^14+2048 bytes, or a record decrypted to a TLSCompressed record
+with more than 2^14+1024 bytes. This message is always fatal.
+
+=item "CA"/"unknown CA"
+
+A valid certificate chain or partial chain was received, but the
+certificate was not accepted because the CA certificate could not
+be located or couldn't be matched with a known, trusted CA.  This
+message is always fatal.
+
+=item "AD"/"access denied"
+
+A valid certificate was received, but when access control was
+applied, the sender decided not to proceed with negotiation.
+This message is always fatal.
+
+=item "DE"/"decode error"
+
+A message could not be decoded because some field was out of the
+specified range or the length of the message was incorrect. This
+message is always fatal.
+
+=item "CY"/"decrypt error"
+
+A handshake cryptographic operation failed, including being
+unable to correctly verify a signature, decrypt a key exchange,
+or validate a finished message.
+
+=item "ER"/"export restriction"
+
+A negotiation not in compliance with export restrictions was
+detected; for example, attempting to transfer a 1024 bit
+ephemeral RSA key for the RSA_EXPORT handshake method. This
+message is always fatal.
+
+=item "PV"/"protocol version"
+
+The protocol version the client has attempted to negotiate is
+recognized, but not supported. (For example, old protocol
+versions might be avoided for security reasons). This message is
+always fatal.
+
+=item "IS"/"insufficient security"
+
+Returned instead of handshake_failure when a negotiation has
+failed specifically because the server requires ciphers more
+secure than those supported by the client. This message is always
+fatal.
+
+=item "IE"/"internal error"
+
+An internal error unrelated to the peer or the correctness of the
+protocol makes it impossible to continue (such as a memory
+allocation failure). This message is always fatal.
+
+=item "US"/"user canceled"
+
+This handshake is being canceled for some reason unrelated to a
+protocol failure. If the user cancels an operation after the
+handshake is complete, just closing the connection by sending a
+close_notify is more appropriate. This alert should be followed
+by a close_notify. This message is generally a warning.
+
+=item "NR"/"no renegotiation"
+
+Sent by the client in response to a hello request or by the
+server in response to a client hello after initial handshaking.
+Either of these would normally lead to renegotiation; when that
+is not appropriate, the recipient should respond with this alert;
+at that point, the original requester can decide whether to
+proceed with the connection. One case where this would be
+appropriate would be where a server has spawned a process to
+satisfy a request; the process might receive security parameters
+(key length, authentication, etc.) at startup and it might be
+difficult to communicate changes to these parameters after that
+point. This message is always a warning.
+
+=item "UP"/"unknown PSK identity"
+
+Sent by the server to indicate that it does not recognize a PSK
+identity or an SRP identity. 
+
+=item "UK"/"unknown"
+
+This indicates that no description is available for this alert type.
+Probably B<value> does not contain a correct alert message.

+=head1 DESCRIPTION
+
+SSL_check_chain() checks whether certificate B<x>, private key B<pk> and
+certificate chain B<chain> is suitable for use with the current session
+B<s>.
+
+=head1 RETURN VALUES
+
+SSL_check_chain() returns a bitmap of flags indicating the validity of the
+chain.
+
+B<CERT_PKEY_VALID>: the chain can be used with the current session.
+If this flag is B<not> set then the certificate will never be used even
+if the application tries to set it because it is inconsistent with the
+peer preferences.
+
+B<CERT_PKEY_SIGN>: the EE key can be used for signing.
+
+B<CERT_PKEY_EE_SIGNATURE>: the signature algorithm of the EE certificate is
+acceptable.
+
+B<CERT_PKEY_CA_SIGNATURE>: the signature algorithms of all CA certificates
+are acceptable.
+
+B<CERT_PKEY_EE_PARAM>: the parameters of the end entity certificate are
+acceptable (e.g. it is a supported curve).
+
+B<CERT_PKEY_CA_PARAM>: the parameters of all CA certificates are acceptable.
+
+B<CERT_PKEY_EXPLICIT_SIGN>: the end entity certificate algorithm
+can be used explicitly for signing (i.e. it is mentioned in the signature
+algorithms extension).
+
+B<CERT_PKEY_ISSUER_NAME>: the issuer name is acceptable. This is only
+meaningful for client authentication.
+
+B<CERT_PKEY_CERT_TYPE>: the certificate type is acceptable. Only meaningful
+for client authentication.
+
+B<CERT_PKEY_SUITEB>: chain is suitable for Suite B use.
+
+=head1 NOTES
+
+SSL_check_chain() must be called in servers after a client hello message or in
+clients after a certificate request message. It will typically be called
+in the certificate callback.
+
+An application wishing to support multiple certificate chains may call this
+function on each chain in turn: starting with the one it considers the
+most secure. It could then use the chain of the first set which returns
+suitable flags.
+
+As a minimum the flag B<CERT_PKEY_VALID> must be set for a chain to be
+usable. An application supporting multiple chains with different CA signature
+algorithms may also wish to check B<CERT_PKEY_CA_SIGNATURE> too. If no
+chain is suitable a server should fall back to the most secure chain which
+sets B<CERT_PKEY_VALID>.
+
+The validity of a chain is determined by checking if it matches a supported
+signature algorithm, supported curves and in the case of client authentication
+certificate types and issuer names.
+
+Since the supported signature algorithms extension is only used in TLS 1.2
+and DTLS 1.2 the results for earlier versions of TLS and DTLS may not be
+very useful. Applications may wish to specify a different "legacy" chain
+for earlier versions of TLS or DTLS.

+SSL_clear - reset SSL object to allow another connection

+
+=head1 DESCRIPTION
+
+Reset B<ssl> to allow another connection. All settings (method, ciphers,
+BIOs) are kept.
+
+=head1 NOTES
+
+SSL_clear is used to prepare an SSL object for a new connection. While all
+settings are kept, a side effect is the handling of the current SSL session.
+If a session is still B<open>, it is considered bad and will be removed
+from the session cache, as required by RFC2246. A session is considered open,
+if L<SSL_shutdown(3)|SSL_shutdown(3)> was not called for the connection
+or at least L<SSL_set_shutdown(3)|SSL_set_shutdown(3)> was used to
+set the SSL_SENT_SHUTDOWN state.
+
+If a session was closed cleanly, the session object will be kept and all
+settings corresponding. This explicitly means, that e.g. the special method
+used during the session will be kept for the next handshake. So if the
+session was a TLSv1 session, a SSL client object will use a TLSv1 client
+method for the next handshake and a SSL server object will use a TLSv1
+server method, even if SSLv23_*_methods were chosen on startup. This
+will might lead to connection failures (see L<SSL_new(3)|SSL_new(3)>)
+for a description of the method's properties.
+
+=head1 WARNINGS
+
+SSL_clear() resets the SSL object to allow for another connection. The
+reset operation however keeps several settings of the last sessions
+(some of these settings were made automatically during the last
+handshake). It only makes sense for a new connection with the exact
+same peer that shares these settings, and may fail if that peer
+changes its settings between connections. Use the sequence
+L<SSL_get_session(3)|SSL_get_session(3)>;
+L<SSL_new(3)|SSL_new(3)>;
+L<SSL_set_session(3)|SSL_set_session(3)>;

+SSL_get_error - obtain result code for TLS/SSL I/O operation
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ int SSL_get_error(const SSL *ssl, int ret);
+
+=head1 DESCRIPTION
+
+SSL_get_error() returns a result code (suitable for the C "switch"
+statement) for a preceding call to SSL_connect(), SSL_accept(), SSL_do_handshake(),
+SSL_read(), SSL_peek(), or SSL_write() on B<ssl>.  The value returned by
+that TLS/SSL I/O function must be passed to SSL_get_error() in parameter
+B<ret>.
+
+In addition to B<ssl> and B<ret>, SSL_get_error() inspects the
+current thread's OpenSSL error queue.  Thus, SSL_get_error() must be
+used in the same thread that performed the TLS/SSL I/O operation, and no
+other OpenSSL function calls should appear in between.  The current
+thread's error queue must be empty before the TLS/SSL I/O operation is
+attempted, or SSL_get_error() will not work reliably.
+
+=head1 RETURN VALUES
+
+The following return values can currently occur:
+
+=over 4
+
+=item SSL_ERROR_NONE
+
+The TLS/SSL I/O operation completed.  This result code is returned
+if and only if B<ret E<gt> 0>.
+
+=item SSL_ERROR_ZERO_RETURN
+
+The TLS/SSL connection has been closed.
+If the protocol version is SSL 3.0 or higher, this result code is returned only
+if a closure alert has occurred in the protocol, i.e. if the connection has been
+closed cleanly.
+Note that in this case B<SSL_ERROR_ZERO_RETURN> does not necessarily
+indicate that the underlying transport has been closed.
+
+
+=item SSL_ERROR_WANT_READ, SSL_ERROR_WANT_WRITE
+
+The operation did not complete; the same TLS/SSL I/O function should be
+called again later.  If, by then, the underlying B<BIO> has data
+available for reading (if the result code is B<SSL_ERROR_WANT_READ>)
+or allows writing data (B<SSL_ERROR_WANT_WRITE>), then some TLS/SSL
+protocol progress will take place, i.e. at least part of an TLS/SSL
+record will be read or written.  Note that the retry may again lead to
+a B<SSL_ERROR_WANT_READ> or B<SSL_ERROR_WANT_WRITE> condition.
+There is no fixed upper limit for the number of iterations that
+may be necessary until progress becomes visible at application
+protocol level.
+
+For socket B<BIO>s (e.g. when SSL_set_fd() was used), select() or
+poll() on the underlying socket can be used to find out when the
+TLS/SSL I/O function should be retried.
+
+Caveat: Any TLS/SSL I/O function can lead to either of
+B<SSL_ERROR_WANT_READ> and B<SSL_ERROR_WANT_WRITE>.  In particular,
+SSL_read() or SSL_peek() may want to write data and SSL_write() may want
+to read data.  This is mainly because TLS/SSL handshakes may occur at any
+time during the protocol (initiated by either the client or the server);
+SSL_read(), SSL_peek(), and SSL_write() will handle any pending handshakes.
+
+=item SSL_ERROR_WANT_CONNECT, SSL_ERROR_WANT_ACCEPT
+
+The operation did not complete; the same TLS/SSL I/O function should be
+called again later. The underlying BIO was not connected yet to the peer
+and the call would block in connect()/accept(). The SSL function should be
+called again when the connection is established. These messages can only
+appear with a BIO_s_connect() or BIO_s_accept() BIO, respectively.
+In order to find out, when the connection has been successfully established,
+on many platforms select() or poll() for writing on the socket file descriptor
+can be used.
+
+=item SSL_ERROR_WANT_X509_LOOKUP
+
+The operation did not complete because an application callback set by
+SSL_CTX_set_client_cert_cb() has asked to be called again.
+The TLS/SSL I/O function should be called again later.
+Details depend on the application.
+
+=item SSL_ERROR_SYSCALL
+
+Some non-recoverable I/O error occurred.
+The OpenSSL error queue may contain more information on the error.
+For socket I/O on Unix systems, consult B<errno> for details.

+SSL_get_ex_data_X509_STORE_CTX_idx() returns the index number under which

+
+=head1 NOTES
+
+Whenever a X509_STORE_CTX object is created for the verification of the

+To retrieve this pointer the X509_STORE_CTX_get_ex_data() function can
+be used with the correct index. This index is globally the same for all
+X509_STORE_CTX objects and can be retrieved using
+SSL_get_ex_data_X509_STORE_CTX_idx(). The index value is set when
+SSL_get_ex_data_X509_STORE_CTX_idx() is first called either by the application
+program directly or indirectly during other SSL setup functions or during

+Several OpenSSL structures can have application specific data attached to them.
+These functions are used internally by OpenSSL to manipulate application
+specific data attached to a specific structure.
+
+SSL_get_ex_new_index() is used to register a new index for application

+
+SSL_set_ex_data() is used to store application data at B<arg> for B<idx> into
+the B<ssl> object.
+
+SSL_get_ex_data() is used to retrieve the information for B<idx> from
+B<ssl>.

+
+=head1 NOTES
+
+Due to the protocol definition, a TLS/SSL server will always send a

+
+SSL_get_session() returns a pointer to the B<SSL_SESSION> actually used in

+that the pointer can become invalid by other operations.
+
+SSL_get0_session() is the same as SSL_get_session().
+
+SSL_get1_session() is the same as SSL_get_session(), but the reference
+count of the B<SSL_SESSION> is incremented by one.
+
+=head1 NOTES
+
+The ssl session contains all information required to re-establish the
+connection without a new handshake.
+
+SSL_get0_session() returns a pointer to the actual session. As the
+reference counter is not incremented, the pointer is only valid while
+the connection is in use. If L<SSL_clear(3)|SSL_clear(3)> or
+L<SSL_free(3)|SSL_free(3)> is called, the session may be removed completely
+(if considered bad), and the pointer obtained will become invalid. Even
+if the session is valid, it can be removed at any time due to timeout
+during L<SSL_CTX_flush_sessions(3)|SSL_CTX_flush_sessions(3)>.
+
+If the data is to be kept, SSL_get1_session() will increment the reference
+count, so that the session will not be implicitly removed by other operations
+but stays in memory. In order to remove the session
+L<SSL_SESSION_free(3)|SSL_SESSION_free(3)> must be explicitly called once
+to decrement the reference count again.
+
+SSL_SESSION objects keep internal link information about the session cache
+list, when being inserted into one SSL_CTX object's session cache.
+One SSL_SESSION object, regardless of its reference count, must therefore
+only be used with one SSL_CTX object (and the SSL objects created
+from this SSL_CTX object).

+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ int SSL_read(SSL *ssl, void *buf, int num);
+
+=head1 DESCRIPTION
+
+SSL_read() tries to read B<num> bytes from the specified B<ssl> into the
+buffer B<buf>.
+
+=head1 NOTES
+
+If necessary, SSL_read() will negotiate a TLS/SSL session, if
+not already explicitly performed by L<SSL_connect(3)|SSL_connect(3)> or
+L<SSL_accept(3)|SSL_accept(3)>. If the
+peer requests a re-negotiation, it will be performed transparently during
+the SSL_read() operation. The behaviour of SSL_read() depends on the
+underlying BIO. 
+
+For the transparent negotiation to succeed, the B<ssl> must have been
+initialized to client or server mode. This is being done by calling
+L<SSL_set_connect_state(3)|SSL_set_connect_state(3)> or SSL_set_accept_state()
+before the first call to an SSL_read() or L<SSL_write(3)|SSL_write(3)>
+function.
+
+SSL_read() works based on the SSL/TLS records. The data are received in
+records (with a maximum record size of 16kB for SSLv3/TLSv1). Only when a
+record has been completely received, it can be processed (decryption and
+check of integrity). Therefore data that was not retrieved at the last
+call of SSL_read() can still be buffered inside the SSL layer and will be
+retrieved on the next call to SSL_read(). If B<num> is higher than the
+number of bytes buffered, SSL_read() will return with the bytes buffered.
+If no more bytes are in the buffer, SSL_read() will trigger the processing
+of the next record. Only when the record has been received and processed
+completely, SSL_read() will return reporting success. At most the contents
+of the record will be returned. As the size of an SSL/TLS record may exceed
+the maximum packet size of the underlying transport (e.g. TCP), it may
+be necessary to read several packets from the transport layer before the
+record is complete and SSL_read() can succeed.
+
+If the underlying BIO is B<blocking>, SSL_read() will only return, once the
+read operation has been finished or an error occurred, except when a
+renegotiation take place, in which case a SSL_ERROR_WANT_READ may occur. 
+This behaviour can be controlled with the SSL_MODE_AUTO_RETRY flag of the
+L<SSL_CTX_set_mode(3)|SSL_CTX_set_mode(3)> call.
+
+If the underlying BIO is B<non-blocking>, SSL_read() will also return
+when the underlying BIO could not satisfy the needs of SSL_read()
+to continue the operation. In this case a call to
+L<SSL_get_error(3)|SSL_get_error(3)> with the
+return value of SSL_read() will yield B<SSL_ERROR_WANT_READ> or
+B<SSL_ERROR_WANT_WRITE>. As at any time a re-negotiation is possible, a
+call to SSL_read() can also cause write operations! The calling process
+then must repeat the call after taking appropriate action to satisfy the
+needs of SSL_read(). The action depends on the underlying BIO. When using a
+non-blocking socket, nothing is to be done, but select() can be used to check
+for the required condition. When using a buffering BIO, like a BIO pair, data
+must be written into or retrieved out of the BIO before being able to continue.
+
+L<SSL_pending(3)|SSL_pending(3)> can be used to find out whether there
+are buffered bytes available for immediate retrieval. In this case
+SSL_read() can be called without blocking or actually receiving new
+data from the underlying socket.
+
+=head1 WARNING
+
+When an SSL_read() operation has to be repeated because of
+B<SSL_ERROR_WANT_READ> or B<SSL_ERROR_WANT_WRITE>, it must be repeated
+with the same arguments.
+
+=head1 RETURN VALUES
+
+The following return values can occur:
+
+=over 4
+
+=item E<gt> 0
+
+The read operation was successful.
+The return value is the number of bytes actually read from the TLS/SSL

+
+=item Z<><= 0
+
+
+=item E<lt>0
+
+The read operation was not successful, because either the connection was closed,
+an error occurred or action must be taken by the calling process.
+Call L<SSL_get_error(3)> with the return value B<ret> to find out the reason.
+
+SSLv2 (deprecated) does not support a shutdown alert protocol, so it can
+only be detected, whether the underlying connection was closed. It cannot
+be checked, whether the closure was initiated by the peer or by something

+
+SSL_shutdown - shut down a TLS/SSL connection
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ int SSL_shutdown(SSL *ssl);
+
+=head1 DESCRIPTION
+
+SSL_shutdown() shuts down an active TLS/SSL connection. It sends the 
+"close notify" shutdown alert to the peer.
+
+=head1 NOTES
+
+SSL_shutdown() tries to send the "close notify" shutdown alert to the peer.
+Whether the operation succeeds or not, the SSL_SENT_SHUTDOWN flag is set and
+a currently open session is considered closed and good and will be kept in the
+session cache for further reuse.
+
+The shutdown procedure consists of 2 steps: the sending of the "close notify"
+shutdown alert and the reception of the peer's "close notify" shutdown
+alert. According to the TLS standard, it is acceptable for an application
+to only send its shutdown alert and then close the underlying connection
+without waiting for the peer's response (this way resources can be saved,
+as the process can already terminate or serve another connection).
+When the underlying connection shall be used for more communications, the
+complete shutdown procedure (bidirectional "close notify" alerts) must be
+performed, so that the peers stay synchronized.
+
+SSL_shutdown() supports both uni- and bidirectional shutdown by its 2 step
+behaviour.
+
+=over 4
+
+=item When the application is the first party to send the "close notify"
+alert, SSL_shutdown() will only send the alert and then set the
+SSL_SENT_SHUTDOWN flag (so that the session is considered good and will
+be kept in cache). SSL_shutdown() will then return with 0. If a unidirectional
+shutdown is enough (the underlying connection shall be closed anyway), this
+first call to SSL_shutdown() is sufficient. In order to complete the
+bidirectional shutdown handshake, SSL_shutdown() must be called again.
+The second call will make SSL_shutdown() wait for the peer's "close notify"
+shutdown alert. On success, the second call to SSL_shutdown() will return
+with 1.
+
+=item If the peer already sent the "close notify" alert B<and> it was
+already processed implicitly inside another function
+(L<SSL_read(3)|SSL_read(3)>), the SSL_RECEIVED_SHUTDOWN flag is set.
+SSL_shutdown() will send the "close notify" alert, set the SSL_SENT_SHUTDOWN
+flag and will immediately return with 1.
+Whether SSL_RECEIVED_SHUTDOWN is already set can be checked using the
+SSL_get_shutdown() (see also L<SSL_set_shutdown(3)|SSL_set_shutdown(3)> call.
+
+=back
+
+It is therefore recommended, to check the return value of SSL_shutdown()
+and call SSL_shutdown() again, if the bidirectional shutdown is not yet
+complete (return value of the first call is 0). As the shutdown is not
+specially handled in the SSLv2 protocol, SSL_shutdown() will succeed on
+the first call.
+
+The behaviour of SSL_shutdown() additionally depends on the underlying BIO. 
+
+If the underlying BIO is B<blocking>, SSL_shutdown() will only return once the
+handshake step has been finished or an error occurred.
+
+If the underlying BIO is B<non-blocking>, SSL_shutdown() will also return
+when the underlying BIO could not satisfy the needs of SSL_shutdown()
+to continue the handshake. In this case a call to SSL_get_error() with the
+return value of SSL_shutdown() will yield B<SSL_ERROR_WANT_READ> or
+B<SSL_ERROR_WANT_WRITE>. The calling process then must repeat the call after
+taking appropriate action to satisfy the needs of SSL_shutdown().
+The action depends on the underlying BIO. When using a non-blocking socket,
+nothing is to be done, but select() can be used to check for the required
+condition. When using a buffering BIO, like a BIO pair, data must be written
+into or retrieved out of the BIO before being able to continue.
+
+SSL_shutdown() can be modified to only set the connection to "shutdown"
+state but not actually send the "close notify" alert messages,
+see L<SSL_CTX_set_quiet_shutdown(3)|SSL_CTX_set_quiet_shutdown(3)>.
+When "quiet shutdown" is enabled, SSL_shutdown() will always succeed
+and return 1.
+
+=head1 RETURN VALUES
+
+The following return values can occur:
+
+=over 4
+
+=item Z<>0
+
+The shutdown is not yet finished. Call SSL_shutdown() for a second time,
+if a bidirectional shutdown shall be performed.
+The output of L<SSL_get_error(3)|SSL_get_error(3)> may be misleading, as an
+erroneous SSL_ERROR_SYSCALL may be flagged even though no error occurred.
+
+=item Z<>1
+
+The shutdown was successfully completed. The "close notify" alert was sent
+and the peer's "close notify" alert was received.
+
+=item E<lt>0
+
+The shutdown was not successful because a fatal error occurred either
+at the protocol level or a connection failure occurred. It can also occur if
+action is need to continue the operation for non-blocking BIOs.

+SSL_state_string() returns a 6 letter string indicating the current state

+
+SSL_state_string_long() returns a string indicating the current state of

+
+During its use, an SSL objects passes several states. The state is internally

+
+When using non-blocking sockets, the function call performing the handshake
+may return with SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE condition,
+so that SSL_state_string[_long]() may be called.
+
+For both blocking or non-blocking sockets, the details state information
+can be used within the info_callback function set with the

+=head1 DESCRIPTION
+
+SSL_want() returns state information for the SSL object B<ssl>.
+
+The other SSL_want_*() calls are shortcuts for the possible states returned
+by SSL_want().
+
+=head1 NOTES
+
+SSL_want() examines the internal state information of the SSL object. Its
+return values are similar to that of L<SSL_get_error(3)|SSL_get_error(3)>.
+Unlike L<SSL_get_error(3)|SSL_get_error(3)>, which also evaluates the
+error queue, the results are obtained by examining an internal state flag
+only. The information must therefore only be used for normal operation under
+non-blocking I/O. Error conditions are not handled and must be treated
+using L<SSL_get_error(3)|SSL_get_error(3)>.
+
+The result returned by SSL_want() should always be consistent with
+the result of L<SSL_get_error(3)|SSL_get_error(3)>.

+=head1 NAME
+
+SSL_write - write bytes to a TLS/SSL connection.
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ int SSL_write(SSL *ssl, const void *buf, int num);
+
+=head1 DESCRIPTION
+
+SSL_write() writes B<num> bytes from the buffer B<buf> into the specified
+B<ssl> connection.
+
+=head1 NOTES
+
+If necessary, SSL_write() will negotiate a TLS/SSL session, if
+not already explicitly performed by L<SSL_connect(3)|SSL_connect(3)> or
+L<SSL_accept(3)|SSL_accept(3)>. If the
+peer requests a re-negotiation, it will be performed transparently during
+the SSL_write() operation. The behaviour of SSL_write() depends on the
+underlying BIO. 
+
+For the transparent negotiation to succeed, the B<ssl> must have been
+initialized to client or server mode. This is being done by calling
+L<SSL_set_connect_state(3)|SSL_set_connect_state(3)> or SSL_set_accept_state()
+before the first call to an L<SSL_read(3)|SSL_read(3)> or SSL_write() function.
+
+If the underlying BIO is B<blocking>, SSL_write() will only return, once the
+write operation has been finished or an error occurred, except when a
+renegotiation take place, in which case a SSL_ERROR_WANT_READ may occur. 
+This behaviour can be controlled with the SSL_MODE_AUTO_RETRY flag of the
+L<SSL_CTX_set_mode(3)|SSL_CTX_set_mode(3)> call.
+
+If the underlying BIO is B<non-blocking>, SSL_write() will also return,
+when the underlying BIO could not satisfy the needs of SSL_write()
+to continue the operation. In this case a call to
+L<SSL_get_error(3)|SSL_get_error(3)> with the
+return value of SSL_write() will yield B<SSL_ERROR_WANT_READ> or
+B<SSL_ERROR_WANT_WRITE>. As at any time a re-negotiation is possible, a
+call to SSL_write() can also cause read operations! The calling process
+then must repeat the call after taking appropriate action to satisfy the
+needs of SSL_write(). The action depends on the underlying BIO. When using a
+non-blocking socket, nothing is to be done, but select() can be used to check
+for the required condition. When using a buffering BIO, like a BIO pair, data
+must be written into or retrieved out of the BIO before being able to continue.
+
+SSL_write() will only return with success, when the complete contents
+of B<buf> of length B<num> has been written. This default behaviour
+can be changed with the SSL_MODE_ENABLE_PARTIAL_WRITE option of
+L<SSL_CTX_set_mode(3)|SSL_CTX_set_mode(3)>. When this flag is set,
+SSL_write() will also return with success, when a partial write has been
+successfully completed. In this case the SSL_write() operation is considered
+completed. The bytes are sent and a new SSL_write() operation with a new
+buffer (with the already sent bytes removed) must be started.
+A partial write is performed with the size of a message block, which is
+16kB for SSLv3/TLSv1.
+
+=head1 WARNING
+
+When an SSL_write() operation has to be repeated because of
+B<SSL_ERROR_WANT_READ> or B<SSL_ERROR_WANT_WRITE>, it must be repeated
+with the same arguments.
+
+When calling SSL_write() with num=0 bytes to be sent the behaviour is
+undefined.
+
+=head1 RETURN VALUES
+
+The following return values can occur:
+
+=over 4
+
+=item E<gt> 0
+
+The write operation was successful, the return value is the number of
+bytes actually written to the TLS/SSL connection.
+
+=item Z<><= 0
+
+The write operation was not successful, because either the connection was
+closed, an error occurred or action must be taken by the calling process.
+Call SSL_get_error() with the return value B<ret> to find out the reason.
+
+SSLv2 (deprecated) does not support a shutdown alert protocol, so it can
+only be detected, whether the underlying connection was closed. It cannot
+be checked, why the closure happened.
+
+Old documentation indicated a difference between 0 and -1, and that -1 was
+retryable.
+You should instead call SSL_get_error() to find out if it's retryable.

+d2i_SSL_SESSION, i2d_SSL_SESSION - convert SSL_SESSION object from/to ASN1 representation
+
+=head1 SYNOPSIS

+ #include <openssl/ssl.h>
+
+ SSL_SESSION *d2i_SSL_SESSION(SSL_SESSION **a, const unsigned char **pp, long length);
+ int i2d_SSL_SESSION(SSL_SESSION *in, unsigned char **pp);
+
+=head1 DESCRIPTION
+
+d2i_SSL_SESSION() transforms the external ASN1 representation of an SSL/TLS
+session, stored as binary data at location B<pp> with length B<length>, into
+an SSL_SESSION object.
+
+i2d_SSL_SESSION() transforms the SSL_SESSION object B<in> into the ASN1
+representation and stores it into the memory location pointed to by B<pp>.
+The length of the resulting ASN1 representation is returned. If B<pp> is
+the NULL pointer, only the length is calculated and returned.
+
+=head1 NOTES
+
+The SSL_SESSION object is built from several malloc()ed parts, it can
+therefore not be moved, copied or stored directly. In order to store
+session data on disk or into a database, it must be transformed into
+a binary ASN1 representation.
+
+When using d2i_SSL_SESSION(), the SSL_SESSION object is automatically
+allocated. The reference count is 1, so that the session must be
+explicitly removed using L<SSL_SESSION_free(3)|SSL_SESSION_free(3)>,
+unless the SSL_SESSION object is completely taken over, when being called
+inside the get_session_cb() (see
+L<SSL_CTX_sess_set_get_cb(3)|SSL_CTX_sess_set_get_cb(3)>).
+
+SSL_SESSION objects keep internal link information about the session cache
+list, when being inserted into one SSL_CTX object's session cache.
+One SSL_SESSION object, regardless of its reference count, must therefore
+only be used with one SSL_CTX object (and the SSL objects created
+from this SSL_CTX object).
+
+When using i2d_SSL_SESSION(), the memory location pointed to by B<pp> must be
+large enough to hold the binary representation of the session. There is no
+known limit on the size of the created ASN1 representation, so the necessary
+amount of space should be obtained by first calling i2d_SSL_SESSION() with
+B<pp=NULL>, and obtain the size needed, then allocate the memory and
+call i2d_SSL_SESSION() again.
+Note that this will advance the value contained in B<*pp> so it is necessary
+to save a copy of the original allocation.
+For example:
+ int i,j;
+ char *p, *temp;
+ i = i2d_SSL_SESSION(sess, NULL);
+ p = temp = malloc(i);
+ j = i2d_SSL_SESSION(sess, &temp);
+ assert(i == j);
+ assert(p+i == temp);
+
+=head1 RETURN VALUES
+
+d2i_SSL_SESSION() returns a pointer to the newly allocated SSL_SESSION
+object. In case of failure the NULL-pointer is returned and the error message
+can be retrieved from the error stack.
+
+i2d_SSL_SESSION() returns the size of the ASN1 representation in bytes.
+When the session is not valid, B<0> is returned and no operation is performed.

+=head1 NAME
+
+SSL - OpenSSL SSL/TLS library
+
+=head1 SYNOPSIS
+
+=head1 DESCRIPTION
+
+The OpenSSL B<ssl> library implements the Secure Sockets Layer (SSL v2/v3) and
+Transport Layer Security (TLS v1) protocols. It provides a rich API which is
+documented here.
+
+At first the library must be initialized; see
+L<SSL_library_init(3)|SSL_library_init(3)>.
+
+Then an B<SSL_CTX> object is created as a framework to establish
+TLS/SSL enabled connections (see L<SSL_CTX_new(3)|SSL_CTX_new(3)>).
+Various options regarding certificates, algorithms etc. can be set
+in this object.
+
+When a network connection has been created, it can be assigned to an
+B<SSL> object. After the B<SSL> object has been created using
+L<SSL_new(3)|SSL_new(3)>, L<SSL_set_fd(3)|SSL_set_fd(3)> or
+L<SSL_set_bio(3)|SSL_set_bio(3)> can be used to associate the network
+connection with the object.
+
+Then the TLS/SSL handshake is performed using
+L<SSL_accept(3)|SSL_accept(3)> or L<SSL_connect(3)|SSL_connect(3)>
+respectively.
+L<SSL_read(3)|SSL_read(3)> and L<SSL_write(3)|SSL_write(3)> are used
+to read and write data on the TLS/SSL connection.
+L<SSL_shutdown(3)|SSL_shutdown(3)> can be used to shut down the
+TLS/SSL connection.
+
+=head1 DATA STRUCTURES
+
+Currently the OpenSSL B<ssl> library functions deals with the following data
+structures:
+
+=over 4
+
+=item B<SSL_METHOD> (SSL Method)
+
+That's a dispatch structure describing the internal B<ssl> library
+methods/functions which implement the various protocol versions (SSLv1, SSLv2
+and TLSv1). It's needed to create an B<SSL_CTX>.
+
+=item B<SSL_CIPHER> (SSL Cipher)
+
+This structure holds the algorithm information for a particular cipher which
+are a core part of the SSL/TLS protocol. The available ciphers are configured
+on a B<SSL_CTX> basis and the actually used ones are then part of the
+B<SSL_SESSION>.
+
+=item B<SSL_CTX> (SSL Context)
+
+That's the global context structure which is created by a server or client
+once per program life-time and which holds mainly default values for the
+B<SSL> structures which are later created for the connections.
+
+=item B<SSL_SESSION> (SSL Session)
+
+This is a structure containing the current TLS/SSL session details for a
+connection: B<SSL_CIPHER>s, client and server certificates, keys, etc.
+
+=item B<SSL> (SSL Connection)
+
+That's the main SSL/TLS structure which is created by a server or client per
+established connection. This actually is the core structure in the SSL API.
+Under run-time the application usually deals with this structure which has
+links to mostly all other structures.
+
+=back
+
+
+=head1 HEADER FILES
+
+Currently the OpenSSL B<ssl> library provides the following C header files
+containing the prototypes for the data structures and and functions:
+
+=over 4
+
+=item B<ssl.h>
+
+That's the common header file for the SSL/TLS API.  Include it into your
+program to make the API of the B<ssl> library available. It internally
+includes both more private SSL headers and headers from the B<crypto> library.
+Whenever you need hard-core details on the internals of the SSL API, look
+inside this header file.
+
+=item B<ssl2.h>
+
+That's the sub header file dealing with the SSLv2 protocol only.
+I<Usually you don't have to include it explicitly because
+it's already included by ssl.h>.
+
+=item B<ssl3.h>
+
+That's the sub header file dealing with the SSLv3 protocol only.
+I<Usually you don't have to include it explicitly because
+it's already included by ssl.h>.
+
+=item B<ssl23.h>
+
+That's the sub header file dealing with the combined use of the SSLv2 and
+SSLv3 protocols.
+I<Usually you don't have to include it explicitly because
+it's already included by ssl.h>.
+
+=item B<tls1.h>
+
+That's the sub header file dealing with the TLSv1 protocol only.
