This is already in next, but I'd like to know why you added the
key/keylen args to each function instead of letting the caller use
digest_set_key()?

In the patch "[PATCH 04/10] command: add generic digest command" you add
another parameter (unsigned char *sig) to these functions, which is used
instead of the key parameter when verifying.

Maybe we are overloading them with to much different functionality? 

Regards,
Jan
