Check your completed copy.

Confirm that the entire PDF—including its signing receipt—matches the completed copy recorded by Docjig.

Your file stays on this device. Your browser sends only its SHA-256 fingerprint and document record ID. No account is needed.

Verify independently, even offline.

New completed documents carry a self-signed Docjig service seal. It protects the agreement, attachments and receipt together. Retain the original PDF, the correct public certificate and verification software while Docjig is available.

Obtain the certificate from a trusted Docjig source. A certificate supplied only by an untrusted document sender is not proof that it belongs to Docjig. PDF readers may report an unknown issuer until you explicitly trust our certificate.

Download the offline Python verifier. Install its dependency while online:

python -m pip install pyhanko==0.37.0

Then run locally with the certificate you trust (use its downloaded filename):

python verify-docjig.py completed.pdf --certificate docjig-CERTIFICATE-ID.pem

The offline verifier makes no network requests. A pass means the complete file is intact under that certificate, assuming its private key was not compromised. It checks all bytes outside the PDF's reserved cryptographic signature container and rejects later appended revisions.

These are integrity checks, not independent verification of human identities or a trusted third-party signing time. The offline tool does not assess certificate expiry or revocation. Account deletion may remove the online reference; previously retained sealed copies remain independently checkable. Older documents may have only a hash record and no embedded seal.
