Signed documents

Verify a signed document

Check that a PDF signed through the Logic Unknown partner portal is exactly the document that was signed.

Check a file

Envelope id24 characters, printed on the signature certificate page.

PDF fileThe file is not uploaded. Your browser computes its fingerprint (SHA-256) and only that is sent.

What this tells you

Signed PDF: the file is the final document with the signature certificate page, unchanged since signing.
Original document: the file is the document that was sent for signature, without the certificate.
No match: the file was changed, or the envelope id is wrong.

Documents are signed with a simple electronic signature: each signer was authenticated by Microsoft sign-in and typed their name. The answer shows the document title, status and completion time, never names or email addresses.
