  2. Russian state standards Encryption GOST 28147-89 - "Cryptographic Protection for Data Processing System“, 1989 Hashing GOST R 34.10-94 - "Information technology. Cryptographic Data Security. Hashing function.", 1994. Digital signature GOST R 34.10-94 - "Information technology. Cryptographic Data Security. Produce and check procedures of Electronic Digital Signatures based on Asymmetric Cryptographic Algorithm.", 1994. GOST R 34.10-2001 - "Information technology. Cryptographic data security. Signature and verification processes of [electronic] digital signature.“, 2001.

  3. Compatibility Algorithm Parameters Encryption S-BOX not defined (except for test values) Digest S-BOX not defined Digital signature P, Q, A not defined (except for test values) Elliptic Curve parameters not defined Russian Federal Digital SignatureLaw, 10 Jan 2002 PKI ready
