+
+SM3_Init,
+SM3_Update,
+SM3_Final
+
+=head1 SYNOPSIS
+
+ #include <openssl/sm3.h>
+
+ unsigned char *SM3(const unsigned char *d, size_t n, unsigned char *md);
+
+ int SM3_Init(SM3_CTX *c);
+ int SM3_Update(SM3_CTX *c, const void *data, size_t len);
+ int SM3_Final(unsigned char *md, SM3_CTX *c);
+
+=head1 DESCRIPTION
+
+SM3 is a cryptographic hash function with a 256-bit output, defined in GB/T
+32905-2016.
+
+SM3() computes the SM3 message digest of the B<n> bytes at B<d> and places it
+in B<md> (which must have space for SM3_DIGEST_LENGTH == 32 bytes of output).
+If B<md> is NULL, the digest is placed in a static array.
+
+The following functions may be used if the message is not completely stored in
+memory:
+
+SM3_Init() initializes a B<SM3_CTX> structure.
+
+SM3_Update() can be called repeatedly with chunks of the message to be hashed
+(B<len> bytes at B<data>).
+
+SM3_Final() places the message digest in B<md>, which must have space for
+B<SM3_DIGEST_LENGTH> == 32 bytes of output, and erases the B<SM3_CTX>.
+
+=head1 RETURN VALUES
+
+=over 4
+
+=item SM3()
+
+Returns pointers to the hash value.
+
+=item SM3_Init(), SM3_Update(), SM3_Final()
+
+Returns 1 for success, 0 otherwise.
+
+=back
+
+=head1 NOTE
+
+Applications should use the higher level functions such as L<EVP_DigestInit(3)>
+instead of calling these functions directly.
