PDF signing with PDF-XChange

Here's how to sign a PDF document in PDF-Xchange:

• In the "Protect" tab, click on "Sign document"


• In the window that appears, choose a certificate from the operating system store or choose the certificate directly from a file.


• By clicking on "View Certificate" you can check if the certificate that will be used to sign the document corresponds to the expected one.


• In the second part, fill in the fields as desired.


• If you want to time stamp your document, check the "Use timestamp server" box. You can then choose a server from the drop-down list or, by clicking on "Change", you can edit and choose another server (ex: http://timestamp.comodoca.com?td=sha256)


• Finally click on "Ok" to add the signature
