In addition to a new cipher with a block length of n=128 bits
(referred to as "Kuznyechik" and described in RFC 7801), Russian
Federal standard GOST R 34.12-2015 includes an updated version of the
block cipher with a block length of n=64 bits and key length of k=256
bits, which is also referred to as "Magma". The algorithm is an
updated version of an older block cipher with a block length of n=64
bits described in GOST 28147-89 (RFC 5830). This document is intended
to be a source of information about the updated version of the 64-bit
cipher. It may facilitate the use of the block cipher in Internet
applications by providing information for developers and users of the
GOST 64-bit cipher with the revised version of the cipher for
encryption and decryption.
