Pure Python 2.7/3.x GOST cryptographic functions library.
|
||
|
||
GOST is GOvernment STandard of Russian Federation (and Soviet Union).
|
||
|
||
* GOST 28147-89 (RFC 5830) block cipher with ECB, CNT (CTR), CFB, MAC,
|
||
CBC (RFC 4357) modes of operation
|
||
* various 28147-89-related S-boxes included
|
||
* GOST R 34.11-94 hash function (RFC 5831)
|
||
* GOST R 34.11-94 based PBKDF2 function
|
||
* GOST R 34.11-2012 Стрибог (Streebog) hash function (RFC 6986)
|
||
* GOST R 34.11-2012 based PBKDF2 function (Р 50.1.111-2016)
|
||
* GOST R 34.10-2001 (RFC 5832) public key signature function
|
||
* GOST R 34.10-2012 (RFC 7091) public key signature function
|
||
* various 34.10 curve parameters included
|
||
* Coordinates conversion from twisted Edwards to Weierstrass form and
|
||
vice versa
|
||
* VKO GOST R 34.10-2001 key agreement function (RFC 4357)
|
||
* VKO GOST R 34.10-2012 key agreement function (RFC 7836)
|
||
* 28147-89 and CryptoPro key wrapping (RFC 4357)
|
||
* 28147-89 CryptoPro key meshing for CFB and CBC modes (RFC 4357)
|
||
* RFC 4491 (using GOST algorithms with X.509) compatibility helpers
|
||
* GOST R 34.12-2015 128-bit block cipher Кузнечик (Kuznechik) (RFC 7801)
|
||
* GOST R 34.12-2015 64-bit block cipher Магма (Magma)
|
||
* GOST R 34.13-2015 padding methods and block cipher modes of operation
|
||
(ECB, CTR, OFB, CBC, CFB, MAC), ISO 10126 padding
|
||
* MGM AEAD mode for 64 and 128 bit ciphers (RFC 9058)
|
||
* CTR-ACPKM, OMAC-ACPKM-Master modes of operation (Р 1323565.1.017-2018)
|
||
* KExp15/KImp15 key export/import functions (Р 1323565.1.017-2018)
|
||
* KDF_GOSTR3411_2012_256, KDF_TREE_GOSTR3411_2012_256 (Р 50.1.113-2016)
|
||
* KEG export key generation function (Р 1323565.1.020-2018)
|
||
* PEP247-compatible hash/MAC functions
|
||
|
||
Known problems: low performance and non time-constant calculations.

Example 34.10-2012 keypair generation, signing and verifying:
|
||
|
||
>>> from pygost.gost3410 import CURVES
|
||
>>> curve = CURVES["id-tc26-gost-3410-12-512-paramSetA"]
|
||
>>> from os import urandom
|
||
>>> prv_raw = urandom(64)
|
||
>>> from pygost.gost3410 import prv_unmarshal
|
||
>>> from pygost.gost3410 import prv_marshal
|
||
>>> prv = prv_unmarshal(prv_raw)
|
||
>>> prv_raw = prv_marshal(curve, prv)
|
||
>>> from pygost.gost3410 import public_key
|
||
>>> pub = public_key(curve, prv)
|
||
>>> from pygost.gost3410 import pub_marshal
|
||
>>> from pygost.utils import hexenc
|
||
>>> print "Public key is:", hexenc(pub_marshal(pub))
|
||
>>> from pygost import gost34112012512
|
||
>>> data_for_signing = b"some data"
|
||
>>> dgst = gost34112012512.new(data_for_signing).digest()
|
||
>>> from pygost.gost3410 import sign
|
||
>>> signature = sign(curve, prv, dgst)
|
||
>>> from pygost.gost3410 import verify
|
||
>>> verify(curve, pub, dgst, signature)
|
||
True
