🇨🇳SM3 Hash Generator
Professional SM3 hash generator supporting Chinese national cryptographic standard with HMAC, file processing, and performance benchmarking capabilities
What is SM3 Hash Algorithm?
SM3 is a cryptographic hash function designed by Xiaoyun Wang et al. and published in 2010 by the Chinese National Cryptographic Administration. It is part of the Chinese National Standard (GB/T 32905-2016) and produces a 256-bit (32-byte) hash value. SM3 is widely used in Chinese digital certificate systems, blockchain applications, and government cryptographic implementations.
