Streebog is a cryptographic hash function defined in the Russian national standard GOST R 34.11-2012 Information Technology – Cryptographic Information Security – Hash Function. It was created to replace an obsolete GOST hash function defined in the old standard GOST R 34.11-94, and as an asymmetric reply to SHA-3 competition by the US National Institute of Standards and Technology. The function is also described in RFC 6986 and one out of hash functions in ISO/IEC 10118-3:2018.
