GOST R 34.12-2015: Block Cipher "Kuznyechik"
Abstract
This document is intended to be a source of information about the
Russian Federal standard GOST R 34.12-2015 describing the block
cipher with a block length of n=128 bits and a key length of k=256
bits, which is also referred to as "Kuznyechik". This algorithm is
one of the set of Russian cryptographic standard algorithms (called
GOST algorithms).

1. Scope
The Russian Federal standard [GOST3412-2015] specifies basic block
ciphers used as cryptographic techniques for information processing
and information protection including the provision of
confidentiality, authenticity, and integrity of information during
information transmission, processing, and storage in computer-aided
systems.
The cryptographic algorithms specified in this standard are designed
both for hardware and software implementation. They comply with
modern cryptographic requirements and put no restrictions on the
confidentiality level of the protected information.
The standard applies to development, operation, and modernization of
the information systems of various purposes.
