Abstract

   This document is intended to be a source of information about the    Russian Federal standard GOST R 34.12-2015 describing the block    cipher with a block length of n=128 bits and a key length of k=256    bits, which is also referred to as "Kuznyechik".  This algorithm is    one of the set of Russian cryptographic standard algorithms (called    GOST algorithms).
