Example 34.10-2012 keypair generation, signing and verifying:
- >>> from pygost.gost3410 import CURVE_PARAMS
- >>> from pygost.gost3410 import GOST3410Curve
- >>> curve = GOST3410Curve(*CURVE_PARAMS["GostR3410_2012_TC26_ParamSetA"])
+ >>> from pygost.gost3410 import CURVES
+ >>> curve = CURVES["id-tc26-gost-3410-12-512-paramSetA"]
>>> from os import urandom
- >>> prv_raw = urandom(32)
+ >>> 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 gost34112012256
+ >>> from pygost import gost34112012512
>>> data_for_signing = b"some data"
- >>> dgst = gost34112012256.new(data_for_signing).digest()
+ >>> dgst = gost34112012512.new(data_for_signing).digest()
>>> from pygost.gost3410 import sign
- >>> signature = sign(curve, prv, dgst, mode=2012)
+ >>> signature = sign(curve, prv, dgst)
>>> from pygost.gost3410 import verify
- >>> verify(curve, pub, dgst, signature, mode=2012)
+ >>> verify(curve, pub, dgst, signature)
True
