EVP_sm3 - SM3 for EVP
#include <openssl/evp.h>
const EVP_MD *EVP_sm3(void);SM3 is a cryptographic hash function with a 256-bit output, defined in GB/T 32905-2016.
The SM3 hash function.
Developers should be aware of the negative performance implications of calling this function multiple times and should consider using EVP_MD_fetch(3) with EVP_MD-SM3(7) instead. See "Performance" in crypto(7) for further information.
These functions return a EVP_MD structure that contains the implementation of the message digest. See EVP_MD_meth_new(3) for details of the EVP_MD structure.
