NAME
EVP_sm3
\- SM3 for EVP
SYNOPSIS
Header "SYNOPSIS" .Vb 1
#include <openssl/evp.h>
\&
const EVP_MD *EVP_sm3(void);
.Ve
DESCRIPTION
Header "DESCRIPTION" SM3 is a cryptographic hash function with a 256-bit output, defined in GB/T
32905-2016.
EVP_sm3() 4
Item "EVP_sm3()" The SM3 hash function.
NOTES
Header "NOTES" Developers should be aware of the negative performance implications of
calling this function multiple times and should consider using
\fBEVP_MD_fetch\|(3) with EVP_MD-SM3\|(7) instead.
See "Performance" in crypto\|(7) for further information.
"RETURN VALUES"
Header "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"
Header "CONFORMING TO" GB/T 32905-2016 and GM/T 0004-2012.
