NAME

       kcapi_md_sm3 - SM3 message digest on one buffer

SYNOPSIS

       ssize_t kcapi_md_sm3(const uint8_t * in, size_t inlen, uint8_t * out, size_t outlen);

ARGUMENTS

       in
           [in] buffer with input data

       inlen
           [in] length of input buffer

       out
           [out] buffer for message digest

       outlen
           [in] length of out

DESCRIPTION

       With this one-shot convenience function, a message digest of the given buffer is
       generated. The output buffer must be allocated by the caller and have at least the length
       of the message digest size for the chosen message digest.

       return size of message digest upon success; -EIO - data cannot be obtained; -ENOMEM -
       buffer is too small for the complete message digest, the buffer is filled with the
       truncated message digest
