Download the PDF

Once everyone has signed, the signed PDF is ready. It is a single document: your PDF with the signatures and the audit certificate at the end.

Where to get it

  • On the status page with "Download PDF".
  • In the dashboard, next to the document.
  • Through the signing link: whoever signed can download it there too.

You get an e-mail with the last signature. Before that there is no PDF, not even a partial one.

What the document contains

  • Every signature in its place with a stamp: name, role if given, time with time zone and document ID.
  • The document ID on every page, so that even a printout leads back to the verification page.
  • A timestamp from DigiCert under RFC 3161.

The audit certificate

  • for each signature: time, IP address and device
  • how it was made (typed, drawn, uploaded or saved) and how the person was signed in
  • for a personal link, the address it was delivered to
  • hashes of the original files and the history of all events
  • a QR code to the verification page and instructions for checking

One version

canusign builds the PDF once and stores it. Every later download returns the same file, which is why it matches the hash on the verification page. Downloading costs nothing more; the document was paid for when you finalized it.
