SM3 (hash function)

SM3 is a cryptographic hash function that was designed in China. It is part of the SM (Shenzhen Mall) series of cryptographic standards developed and published by the Chinese government. SM3 produces a fixed-size output of 256 bits and is similar in purpose to other well-known hash functions like SHA-256. ### Key Characteristics of SM3: 1. **Output Size**: SM3 produces a hash value that is 256 bits (32 bytes) long.
