ShangMi 3 (SM3) is a cryptographic hash function, standardised for use in commercial cryptography in China.[1] It was published by the State Cryptography Administration (Chinese: 国家密码管理局) on 2010-12-17[2][3] as "GM/T 0004-2012: SM3 cryptographic hash algorithm".[2]
SM3 is used for implementing digital signatures, message authentication codes, and pseudorandom number generators.[4] The algorithm is public[5][6] and is considered similar to SHA-256 in security and efficiency.[7] SM3 can be used with Transport Layer Security[8] although it is not enabled by default.
