We're mixing different terms here: digest and signature

Signature is usually used in the context of public key crypto, digest is
mostly used with for hashes. The command uses both interchangeably.

How about:
-a <algo>	hash or signature algorithm to use
-k <key>	use supplied <key> (ASCII or hex) for MAC
-K <file>	use key from <file> (binary) for MAC
-v <hex>	verify data against supplied <hex> (hash, MAC or signature)
-V <file>	verify data against <file> (hash, MAC or signature)

Regards,
Jan
