DESCRIPTION

14       SM3 is a cryptographic hash function with a 256-bit output, defined in
15       GB/T 32905-2016.

NOTES

21       Developers should be aware of the negative performance implications of
22       calling this function multiple times and should consider using
23       EVP_MD_fetch(3) instead.  See "Performance" in crypto(7) for further
24       information.

RETURN VALUES

27       These functions return a EVP_MD structure that contains the
28       implementation of the message digest. See EVP_MD_meth_new(3) for
29       details of the EVP_MD structure.
