* bpo-40066: [Enum] update str() and format() output (GH-30582)Ethan Furman2022-01-161-1/+0
| | | | | | | | | | | | | | | Undo rejected PEP-663 changes: - restore `repr()` to its 3.10 status - restore `str()` to its 3.10 status New changes: - `IntEnum` and `IntFlag` now leave `__str__` as the original `int.__str__` so that str() and format() return the same result - zero-valued flags without a name have a slightly changed repr(), e.g. `repr(Color(0)) == '<Color: 0>'` - update `dir()` for mixed-in types to return all the methods and attributes of the mixed-in type - added `_numeric_repr_` to `Flag` to control display of unnamed values - enums without doc strings have a more comprehensive doc string added - `ReprEnum` added -- inheriting from this makes it so only `__repr__` is replaced, not `__str__` nor `__format__`; `IntEnum`, `IntFlag`, and `StrEnum` all inherit from `ReprEnum`

* bpo-36076: Add SNI support to ssl.get_server_certificate. (GH-16820)juhovh2021-04-181-1/+1
| | | | | | | | | | | | | | Many servers in the cloud environment require SNI to be used during the SSL/TLS handshake, therefore it is not possible to fetch their certificates using the ssl.get_server_certificate interface. This change adds an additional optional hostname argument that can be used to set the SNI. Note that it is intentionally a separate argument instead of using the host part of the addr tuple, because one might want to explicitly fetch the default certificate or fetch a certificate from a specific IP address with the specified SNI hostname. A separate argument also works better for backwards compatibility. Automerge-Triggered-By: GH:tiran

* bpo-37463: match_hostname requires quad-dotted IPv4 (GH-14499)Christian Heimes2019-07-021-9/+20
| | | | | | | | | | | | | | | | ssl.match_hostname() no longer accepts IPv4 addresses with additional text after the address and only quad-dotted notation without trailing whitespaces. Some inet_aton() implementations ignore whitespace and all data after whitespace, e.g. '127.0.0.1 whatever'. Short notations like '127.1' for '127.0.0.1' were already filtered out.

The default and stdlib contexts also support SSLKEYLOGFILE env var. The msg_callback and related enums are private members. The feature is designed for internal debugging and not for end users.

* bpo-31453: Add setter for min/max protocol version (#5259)Christian Heimes2018-02-271-3/+34
| | | | | | | | | | | | OpenSSL 1.1 has introduced a new API to set the minimum and maximum supported protocol version. The API is easier to use than the old OP_NO_TLS1 option flags, too. Since OpenSSL has no call to set minimum version to highest supported, the implementation emulate maximum_version = MINIMUM_SUPPORTED and minimum_version = MAXIMUM_SUPPORTED by figuring out the minumum and maximum supported version at compile time.

* bpo-32951: Disable SSLSocket/SSLObject constructor (#5864)Christian Heimes2018-02-271-71/+67
| | | | | | | | | | | | | | | | Direct instantiation of SSLSocket and SSLObject objects is now prohibited. The constructors were never documented, tested, or designed as public constructors. The SSLSocket constructor had limitations. For example it was not possible to enabled hostname verification except was ssl_version=PROTOCOL_TLS_CLIENT with cert_reqs=CERT_REQUIRED. SSLContext.wrap_socket() and SSLContext.wrap_bio are the recommended API to construct SSLSocket and SSLObject instances. ssl.wrap_socket() is also deprecated. The only test case for direct instantiation was added a couple of days ago for IDNA testing. Signed-off-by: Christian Heimes <christian@python.org>
* bpo-24334: Cleanup SSLSocket (#5252)Christian Heimes2018-02-241-54/+62
| | | | | | | | | | | | | * The SSLSocket is no longer implemented on top of SSLObject to avoid an extra level of indirection. * Owner and session are now handled in the internal constructor. * _ssl._SSLSocket now uses the same method names as SSLSocket and SSLObject. * Channel binding type check is now handled in C code. Channel binding is always available. The patch also changes the signature of SSLObject.__init__(). In my opinion it's fine. A SSLObject is not a user-constructable object. SSLContext.wrap_bio() is the only valid factory.
* bpo-32819: Simplify and improve ssl.match_hostname (#5620)Christian Heimes2018-02-241-41/+65
| | | | | | | ssl.match_hostname() has been simplified and no longer depends on re and ipaddress module for wildcard and IP addresses. Error reporting for invalid wildcards has been improved. Signed-off-by: Christian Heimes <christian@python.org>
* [bpo-28414] Make all hostnames in SSL module IDN A-labels (GH-5128)Christian Heimes2018-02-241-6/+34
| | | | | | | | | | | | Previously, the ssl module stored international domain names (IDNs) as U-labels. This is problematic for a number of reasons -- for example, it made it impossible for users to use a different version of IDNA than the one built into Python. After this change, we always convert to A-labels as soon as possible, and use them for all internal processing. In particular, server_hostname attribute is now an A-label, and on the server side there's a new sni_callback that receives the SNI servername as an A-label rather than a U-label.
* bpo-31429: Define TLS cipher suite on build time (#3532)Christian Heimes2018-01-291-46/+2
| | | | | | | | | | | | | Until now Python used a hard coded white list of default TLS cipher suites. The old approach has multiple downsides. OpenSSL's default selection was completely overruled. Python did neither benefit from new cipher suites (ChaCha20, TLS 1.3 suites) nor blacklisted cipher suites. For example we used to re-enable 3DES. Python now defaults to OpenSSL DEFAULT cipher suite selection and black lists all unwanted ciphers. Downstream vendors can override the default cipher list with --with-ssl-default-suites.

| | | | | | | | | SSLSocket.wrap_bio() and SSLSocket.wrap_socket() hard-code SSLObject and SSLSocket as return types. In the light of future deprecation of ssl.wrap_socket() module function and direct instantiation of SSLSocket, it is desirable to make the return type of SSLSocket.wrap_bio() and SSLSocket.wrap_socket() customizable.

* bpo-29136: Add TLS 1.3 cipher suites and OP_NO_TLSv1_3 (#1363)Christian Heimes2017-09-081-1/+7
| | | | | | | | | | | | | | | | * bpo-29136: Add TLS 1.3 support TLS 1.3 introduces a new, distinct set of cipher suites. The TLS 1.3 cipher suites don't overlap with cipher suites from TLS 1.2 and earlier. Since Python sets its own set of permitted ciphers, TLS 1.3 handshake will fail as soon as OpenSSL 1.1.1 is released. Let's enable the common AES-GCM and ChaCha20 suites. Additionally the flag OP_NO_TLSv1_3 is added. It defaults to 0 (no op) with OpenSSL prior to 1.1.1. This allows applications to opt-out from TLS 1.3 now.
