Applications should use the higher level functions EVP_DigestInit(3) etc. instead of calling the hash functions directly.
SM3 (ShangMi#3 Hash Algorithm) is a cryptographic hash function with a 256 bit output.
sm3() computes the SM3 message digest of the n bytes at d and places it in md (which must have space for SHA_DIGEST_LENGTH == 20 bytes of output). If md is NULL, the digest is placed in a static array. Note: setting md to NULL is not thread safe.
The following functions may be used if the message is not completely stored in memory:
sm3_nit() initializes a sm3_ctx_t structure.
sm3_update() can be called repeatedly with chunks of the message to be hashed (len bytes at data).
sm3_final() places the message digest in md, which must have space for SM3_DIGEST_LENGTH == 32 bytes of output, and erases the sm3_ctx_t.
sm3_init(), sm3_update(), sm3_final(), sm3_compress() and sm3() return void.
