It was initially defined in the Russian national standard GOST R 34.11-94 <i>Information Technology – Cryptographic Information Security – Hash Function</i>. The equivalent standard used by other member-states of the CIS is GOST 34.311-95.<br><br>This function must not be confused with a different Streebog hash function, which is defined in the new revision of the standard GOST R 34.11-2012.<br><br>The GOST hash function is based on the GOST block cipher.";
