+++ b/openssl/engines/ccgost/README.gost @@ -0,0 +1,300 @@ +GOST ENGINE + +This engine provides implementation of Russian cryptography standard. +This is also an example of adding new cryptoalgorithms into OpenSSL +without changing its core. If OpenSSL is compiled with dynamic engine +support, new algorithms can be added even without recompilation of +OpenSSL and applications which use it. + +ALGORITHMS SUPPORTED + +GOST R 34.10-94 and GOST R 34.10-2001 - digital signature algorithms. + Also support key exchange based on public keys. See RFC 4357 for + details of VKO key exchange algorithm. These algorithms use + 256 bit private keys. Public keys are 1024 bit for 94 and 512 bit for + 2001 (which is elliptic-curve based). Key exchange algorithms + (VKO R 34.10) are supported on these keys too. + +GOST R 34.11-94 Message digest algorithm. 256-bit hash value + +GOST 28147-89 - Symmetric cipher with 256-bit key. Various modes are + defined in the standard, but only CFB and CNT modes are implemented + in the engine. To make statistical analysis more difficult, key + meshing is supported (see RFC 4357). + +GOST 28147-89 MAC mode. Message authentication code. While most MAC + algorithms out there are based on hash functions using HMAC + algorithm, this algoritm is based on symmetric cipher. + It has 256-bit symmetric key and only 32 bits of MAC value + (while HMAC has same key size and value size). + + It is implemented as combination of EVP_PKEY type and EVP_MD type. + +USAGE OF THESE ALGORITHMS + +This engine is designed to allow usage of this algorithms in the +high-level openssl functions, such as PKI, S/MIME and TLS. + +See RFC 4490 for S/MIME with GOST algorithms and RFC 4491 for PKI. +TLS support is implemented according IETF +draft-chudov-cryptopro-cptls-03.txt and is compatible with +CryptoPro CSP 3.0 and 3.6 as well as with MagPro CSP. +GOST ciphersuites implemented in CryptoPro CSP 2.0 are not supported +because they use ciphersuite numbers used now by AES ciphersuites. + +To use the engine you have to load it via openssl configuration +file. Applications should read openssl configuration file or provide +their own means to load engines. Also, applications which operate with +private keys, should use generic EVP_PKEY API instead of using RSA or +other algorithm-specific API. + +CONFIGURATION FILE + +Configuration file should include following statement in the global +section, i.e. before first bracketed section header (see config(5) for details) + + openssl_conf = openssl_def + +where openssl_def is name of the section in configuration file which +describes global defaults. + +This section should contain following statement: + + [openssl_def] + engines = engine_section + +which points to the section which describes list of the engines to be +loaded. This section should contain: + + [engine_section] + gost = gost_section + +And section which describes configuration of the engine should contain + + [gost_section] + engine_id = gost + dynamic_path = /usr/lib/ssl/engines/libgost.so + default_algorithms = ALL + CRYPT_PARAMS = id-Gost28147-89-CryptoPro-A-ParamSet + +Where engine_id parameter specifies name of engine (should be "gost"). +dynamic_path is a location of the loadable shared library implementing the +engine. If the engine is compiled statically or is located in the OpenSSL +engines directory, this line can be omitted. +default_algorithms parameter specifies that all algorithms, provided by +engine, should be used. + +The CRYPT_PARAMS parameter is engine-specific. It allows the user to choose +between different parameter sets of symmetric cipher algorithm. RFC 4357 +specifies several parameters for the GOST 28147-89 algorithm, but OpenSSL +doesn't provide user interface to choose one when encrypting. So use engine +configuration parameter instead. + +Value of this parameter can be either short name, defined in OpenSSL +obj_dat.h header file or numeric representation of OID, defined in RFC +4357. + +USAGE WITH COMMAND LINE openssl UTILITY + +1. Generation of private key + + openssl genpkey -algorithm gost2001 -pkeyopt paramset:A -out seckey.pem + + Use -algorithm option to specify algorithm. + Use -pkeyopt option to pass paramset to algorithm.

TLS operations + +OpenSSL supports all four ciphersuites defined in the IETF draft. +Once you've loaded GOST key and certificate into your TLS server, +ciphersuites which use GOST 28147-89 encryption are enabled. + +Ciphersuites with NULL encryption should be enabled explicitely if +needed. + +GOST2001-GOST89-GOST89 Uses GOST R 34.10-2001 for auth and key exchange + GOST 28147-89 for encryption and GOST 28147-89 MAC +GOST94-GOST89-GOST89 Uses GOST R 34.10-94 for auth and key exchange + GOST 28147-89 for encryption and GOST 28147-89 MAC +GOST2001-NULL-GOST94 Uses GOST R 34.10-2001 for auth and key exchange, + no encryption and HMAC, based on GOST R 34.11-94 +GOST94-NULL-GOST94 Uses GOST R 34.10-94 for auth and key exchange, + no encryption and HMAC, based on GOST R 34.11-94 + +Gost 94 and gost 2001 keys can be used simultaneously in the TLS server. +RSA, DSA and EC keys can be used simultaneously with GOST keys, if +server implementation supports loading more than two private +key/certificate pairs. In this case ciphersuites which use any of loaded +keys would be supported and clients can negotiate ones they wish. + +This allows creation of TLS servers which use GOST ciphersuites for +Russian clients and RSA/DSA ciphersuites for foreign clients. + +5. Calculation of digests and symmetric encryption + OpenSSL provides specific commands (like sha1, aes etc) for calculation + of digests and symmetric encryption. Since such commands cannot be + added dynamically, no such commands are provided for GOST algorithms. + Use generic commands 'dgst' and 'enc'. + + Calculation of GOST R 34.11-94 message digest + + openssl dgst -md_gost94 datafile + + Note that GOST R 34.11-94 specifies that digest value should be + interpreted as little-endian number, but OpenSSL outputs just hex dump + of digest value. + + So, to obtain correct digest value, such as produced by gostsum utility + included in the engine distribution, bytes of output should be + reversed. + + Calculation of HMAC based on GOST R 34.11-94 + + openssl dgst -md_gost94 -mac hmac -macopt key:<32 bytes of key> datafile + + (or use hexkey if key contain NUL bytes) + Calculation of GOST 28147 MAC + + openssl dgst -mac gost-mac -macopt key:<32 bytes of key> datafile + + Note absense of an option that specifies digest algorithm. gost-mac + algorithm supports only one digest (which is actually part of + implementation of this mac) and OpenSSL is clever enough to find out + this. + + Encryption with GOST 28147 CFB mode + openssl enc -gost89 -out encrypted-file -in plain-text-file -k <passphrase> + Encryption with GOST 28147 CNT mode + openssl enc -gost89-cnt -out encrypted-file -in plain-text-file -k <passphrase> + + +6.

EVP_PKEY_derive, intended to use with Diffie-Hellman-like shared key +computing algorithms. + +Although VKO R 34.10 algorithms, described in the RFC 4357 are +definitely second case, engine provides BOTH API for GOST R 34.10 keys. + +EVP_PKEY_derive just invokes appropriate VKO algorithm and computes +256 bit shared key. VKO R 34.10-2001 requires 64 bits of random user key +material (UKM). This UKM should be transmitted to other party, so it is +not generated inside derive function. + +It should be set by EVP_PKEY_CTX_ctrl function using +EVP_PKEY_CTRL_SET_IV command after call of EVP_PKEY_derive_init, but +before EVP_PKEY_derive. + unsigned char ukm[8]; + RAND_bytes(ukm,8); + EVP_PKEY_CTX_ctrl(ctx, -1, EVP_PKEY_OP_DERIVE, 8, ukm) + +EVP_PKEY_encrypt encrypts provided session key with VKO shared key and +packs it into GOST key transport structure, described in the RFC 4490. + +It typically uses ephemeral key pair to compute shared key and packs its +public part along with encrypted key. So, for most cases use of +EVP_PKEY_encrypt/EVP_PKEY_decrypt with GOST keys is almost same as with +RSA. + +However, if peerkey field in the EVP_PKEY_CTX structure is set (using +EVP_PKEY_derive_set_peerkey function) to EVP_PKEY structure which has private +key and uses same parameters as the public key from which this EVP_PKEY_CTX is +created, EVP_PKEY_encrypt will use this private key to compute shared key and +set ephemeral key in the GOST_key_transport structure to NULL. In this case +pkey and peerkey fields in the EVP_PKEY_CTX are used upside-down. + +If EVP_PKEY_decrypt encounters GOST_key_transport structure with NULL +public key field, it tries to use peerkey field from the context to +compute shared key. In this case peerkey field should really contain +peer public key. + +Encrypt operation supports EVP_PKEY_CTRL_SET_IV operation as well. +It can be used when some specific restriction on UKM are imposed by +higher level protocol. For instance, description of GOST ciphersuites +requires UKM to be derived from shared secret. + +If UKM is not set by this control command, encrypt operation would +generate random UKM. + + +This sources include implementation of GOST 28147-89 and GOST R 34.11-94 +which are completely indepentent from OpenSSL and can be used separately +(files gost89.c, gost89.h, gosthash.c, gosthash.h) Utility gostsum (file +gostsum.c) is provided as example of such separate usage. This is +program, simular to md5sum and sha1sum utilities, but calculates GOST R +34.11-94 hash. + +Makefile doesn't include rule for compiling gostsum. +Use command + +$(CC) -o gostsum gostsum.c gost89.c gosthash.c +where $(CC) is name of your C compiler. + +Implementations of GOST R 34.10-xx, including VKO algorithms heavily +depends on OpenSSL BIGNUM and Elliptic Curve libraries. + + diff --git a/openssl/engines/ccgost/e_gost_err.c b/openssl/engines/ccgost/e_gost_err.c new file mode 100644 index 0000000..80ef58f --- /dev/null +++ b/openssl/engines/ccgost/e_gost_err.c @@ -0,0 +1,221 @@ +/* e_gost_err.c */ +/* ==================================================================== + * Copyright (c) 1999-2015 The OpenSSL Project.
