Description

TLSv1.3 implementation currently does not support Russian GOST cipher suites TLS_GOSTR341112_256_WITH_KUZNYECHIK_MGM_L, TLS_GOSTR341112_256_WITH_MAGMA_MGM_L, TLS_GOSTR341112_256_WITH_KUZNYECHIK_MGM_S and TLS_GOSTR341112_256_WITH_MAGMA_MGM_S.

Also there are no SN_, OBJ_ and NID_ defines for underlying algorithms Magma MGM and Kuznyechik MGM.

Contributor guide

Research direction
Study the GOST cipher suites specifications and OpenSSL's TLS implementation. Identify where cipher suites are defined and registered, and how new NIDs and OIDs are added. Then implement the new cipher suites and corresponding defines.
