Allow full 40 char fingerprints to be passed
Allow full 40 char fingerprints to be passed

Some peoople (like me) prefer to validate the entire 40 character
fingerprint. Using just the 8 character fingerprint is known to be
attackable and 16 characters is also shorter than some
security-conscious users like.
