    Sign PDF file with certificate from enterprise CA

    SergeyStepanov

      Hi all,

       

      I have a question about signing PDF documents. I have MS enterprise CA in my network and timestamp server. We use document signing certificates to sign MS office documents.

      Is it possible to sign PDF documents with adobe reader? In Preferences->Security and Preferences->Signatures there are some settings where I can view my certificate and can set timestamp server, but certificates areshowed as not trusted and SIgn with Certificate option is grayed out.

       

      If it is posible to sign PDF documents that way could somebody share with me steps how to do it?

          Signing is currently Acrobat only operation. It is not available in Reader, which is why some commands are grayed out in Reader. You can validate PDF signatures in Reader which is why you can perform commands that are related to signature validation.

          You can use Trusted Identities UI (In 11.x it is in Preferences->Edit->Signatures->Identities & Trusted Certificates->More...) to import your root certificates and set trust. You can also set trust from the Signature Properties dialog (right-click on a signature and select "Show Signature Properties" from the drop-down list). In the Signature Properties dialog click on "Show Signer's Certificate" which will bring up Certificate Viewer dialog in which you can select a certificate in the chain and then click on "Trust" tab to bring up Edit Trust pane.
