Morphology

attestor = attest (transparent) = attest + or

The technical computing sense names the agent (hardware or software) that produces attestations, a straightforward agentive extension of the verb.

Etymology

Attestor in computing also goes back to the Latin testis 'witness' and the idea of attest. In technology an attestor is a piece of hardware or software that 'testifies' with a signed proof about a system's state, so it works like a digital witness that shows someone checking the system that it can be trusted.
