       With this one-shot 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.

       The message digest handle must have been initialized, potentially by also setting the key using the
       generic message digest API functions.

       The input buffer can be at most INT_MAX in size.

       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
