ShangMi (SM) Cipher Suites for TLS 1.3

This document specifies how to use the ShangMi (SM) cryptographic algorithms with Transport Layer Security (TLS) protocol version 1.3. The use of these algorithms with TLS 1.3 is not endorsed by the IETF. The SM algorithms are becoming mandatory in China, so this document provides a description of how to use the SM algorithms with TLS 1.3 and specifies a profile of TLS 1.3 so that implementers can produce interworking implementations.
