You might want to check common/cmd_hash.c and include/hash.h for the 
hash_command() call. It does the resolution of the hash algorithm from it's name 
and you can operate also SHA1 and SHA256 with it. It would be nice if you could 
just extend it a bit and use that instead of adding another ad-hoc mechanism.

Do you think it'd be possible to reuse it please ?
