Abstract

   The purpose of this document is to make the Russian cryptographic
   standards available to the Internet community for their
   implementation in the Transport Layer Security (TLS) Protocol Version
   1.3.

   This specification defines four new cipher suites and seven new
   signature schemes based on GOST R 34.12-2015, GOST R 34.11-2012 and
   GOST R 34.10-2012 algorithms.
