Intel likes to use SHA256(pubkey) for their verification schemes. I guess that reduces the amount of storage while sufficiently secure.

"Hash" is a perfectly valid term, although "fingerprint" would also be correct. "HMAC" is something else entirely.

You don't need an HMAC to verify a key or other blob of data, and isn't fingerprint a less technical term for hash?
