GOST R 34.11-2012: Hash Function
Abstract
This document is intended to be a source of information about the
Russian Federal standard hash function (GOST R 34.11-2012), which is
one of the Russian cryptographic standard algorithms (called GOST
algorithms). This document updates RFC 5831.

1. Scope
The Russian Federal standard hash function (GOST R 34.11-2012)
establishes the hash-function algorithm and the hash-function
calculation procedure for any sequence of binary symbols used in
cryptographic methods of information processing and information
security, including techniques for providing data integrity and
authenticity and for digital signatures during information transfer,
information processing, and information storage in computer-aided
systems.
The hash function defined in the standard provides for the operation
of digital signature systems using the asymmetric cryptographic
algorithm in compliance with GOST R 34.10-2012 [GOST3410-2012].
