The purpose of this document is to make the specifications of the cryptographic algorithms defined by GOST R 34.10-2012 and GOST R 34.11-2012 standards available to the Internet community for their implementation in the cryptographic protocols based on the accompanying algorithms. These specifications define the pseudorandom functions, the key agreement algorithm based on Diffie-Hellman algorithm, the parameters of elliptic curves, the key derivation functions and the key export functions.
