       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
