The GOST hash function is based on this cipher. The new standard also specifies a new 128-bit block cipher called Kuznyechik.<br><br>Developed in the 1970s, the standard had been marked 'Top Secret' and then downgraded to 'Secret' in 1990. Shortly after the dissolution of the USSR, it was declassified and it was released to the public in 1994. GOST 28147 was a Soviet alternative to the United States standard algorithm, DES.

The original standard, published in 1989, did not give the cipher any name, but the most recent revision of the standard, GOST R 34.12-2015 (RFC 7801, RFC 8891), specifies that it may be referred to as Magma. The GOST hash function is based on this cipher. The new standard also specifies a new 128-bit block cipher called Kuznyechik.<br><br>Developed in the 1970s, the standard had been marked 'Top Secret' and then downgraded to 'Secret' in 1990. Shortly after the dissolution of the USSR, it was declassified and it was released to the public in 1994. GOST 28147 was a Soviet alternative to the United States standard algorithm, DES. Thus, the two are very similar in structure.";
