WebLab 4 GOST Hash Function Objectives The GOST hash function was created by the Soviet Union. It is meant to be the standard for hash functions throughout the Soviet Union. The overall structure of GOST is very closely related to the US DES standard. GOST is an iterative function that produces a 256-bit hash value. WebThe GOST block cipher, defined in the standard GOST 28147-89, is a Soviet and Russian government standard symmetric key block cipher. Also based on this block cipher is the GOST hash function . Developed in the 1970s, the standard had been marked "Top Secret" and then downgraded to "Secret" in 1990.
