Check an agreement.
Every agreement completed here carries a Signing Certificate with a code on it. Enter that code and this page will recompute the record from scratch and show you what it found. You do not need an account, and you do not need to have been part of the agreement.
What this page checks
Every action taken on an agreement is recorded as an event, and each event is sealed with a fingerprint that includes the fingerprint of the event before it. Change one event and its fingerprint stops matching. Change one and rebuild its fingerprint, and the next event stops matching instead.
This page recomputes that whole run of fingerprints in front of you and compares the result with the one printed on the certificate. It also shows a fingerprint of each document, so you can confirm the file you were sent is the file that was signed.
