In TLS 1.3, the server signs the handshake transcript to prove identity. RFC 8998 defines the signature scheme sm2sig_sm3 . This means the server signs the handshake hashes using SM2, and the hash algorithm used for that signature is SM3.
Search engines use hexadecimal or alphanumeric commit IDs (e.g., 8fc8a3b ) in their version control systems (like Git). An "UPD" typically means "Update." An observant developer or data analyst may have spotted this ID in a changelog or A/B test header. 8fc8 algorithm upd
