[cm/pub/] with GOST R 34.10-2012.

GOST R 34.10-2012 must be used with Streebog (GOST R 34.11-2012)
hash function. Its digest must be big-endian serialised. Public key
must be in "BE(X)||BE(Y)" format.

Algorithm identifiers for the public key: "gost3410-256A", "gost3410-512C".

Public key's fingerprint should be calculated using big-endian Streebog-256 hash.

Streebog is GOST R 34.11-2012 hashing algorithm.
GOST R 34.10-2012 is signing/key-aggreement algorithm.
