SYNOPSIS

        #include <openssl/evp.h>

        const EVP_MD *EVP_sm3(void);

       "Performance" in crypto(7) for further information.

RETURN VALUES

       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.

CONFORMING TO
