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)
>>> from pygost.gost3410 import prv_unmarshal
>>> verify(curve, pub, dgst, signature, mode=2012)
True
