How Signed PDF works

Signed PDF utilizes industry standard digital certificates, providing evidence of the documents integrity and authenticity, guaranteeing that the information customers receive is accurate and from a known and trusted source.

When a PDF is created or converted from another format, the contents are read and used to automatically calculate a hash, employing cryptographic hash algorithms.  The hash is stored, along with the customer’s public key, within the PDF as the signature. When opened, the contents of the PDF are validated by calculating the document’s hash, using the embedded public key, and comparing it to the hash within the digital signature.

The digital signature verifies that the contents of the PDF have not been modified, and that document metadata such as date created, author, title and other content has not been changed. It can be used on its own, or in conjunction with standard password security on the PDF file. And if the PDF has been tampered with, the digital signature will become invalid, and the recipient will receive an alert when they view the file.
