Multiple Digital Signature Certificates


We are currently printing PDFs using PDF creator and then trying to add signatures with Adobe Reader XI. We are able to add signatures just fine, but the option to add certificates is unavailable.

Can multiple certificates be added through PDF creator, or can certificate adding be enabled when creating the PDF? In Acrobat Standard I believe this is an option to enable adding certificates through Reader.



the option to add certificates with adobe reader needs to be unlocked for every PDF, but it can only be unlocked from Acrobat. It is not part of the pdf specifications. You could use the PDF Architect for adding multiple certificates, but in order to add any certificate with adobe reader it is necessary that the pdf was created with Acrobat.
