Verify a signed document

Choose the PDF you received (the completed agreement, the original, or the certificate). It is checked by its SHA-256 fingerprint; the answer says only whether it matches, when the agreement was completed, how many people signed, and whether the evidence file is intact. Nothing else about the agreement is shown.

Changing even one byte of a signed PDF changes its fingerprint, so an altered copy does not match. For a full offline check use the evidence export and verify.mjs with the published key at /.well-known/bapc-contracts-keys.json. This is not legal advice.
