Surface Forms

signature singular
signatures plural

Morphology

signature = sign (semi-transparent) = sign + ature

The word is formed from 'sign' + the borrowed noun-forming suffix '-ature'; the cryptographic sense is an extended technical use of 'signature', so the relation is meaningful but specialized.

Etymology

Signature in digital security uses the same idea from Latin signare 'to sign': it is a special digital 'mark' made with a secret key that proves a message came from someone and was not changed. So a digital signature works like a written signature for electronic messages.
