Francesco 0 Report post Posted July 15, 2019 Hi all! We are evaluating Nitro Pro 12 but we are having some issues with digitally signed files. We have some digitally signed files (digital sign with certificates from smart card) that results correctly signed in all other PDF readers and online validation tools but in Nitro Pro doesn't appear the Signature Pane icon and I cannot find a way to validate the signature of this specific file. Moreover this informations are visible in an old version of Nitro, Nitro reader 5 and Nitro Pro 10 (the signature pane icon appears). I could send you an example PDF but at the moment it seems that I can not add an attachment to this post. Thanks for your help Share this post Link to post Share on other sites
Steven Zakulec 60 Report post Posted July 15, 2019 Normally, Nitro 12 has a little pop up on the right-hand side that says "This document is signed" when there's a certificate on the document. There's also an icon on the lefthand side- it's a dotted box with an arrow below it. This is the panel that shows where the signatures are in the document, and gives you a basic overview of the certificates. If you're not seeing this, are you on the latest version of Nitro 12? Here's the link to download it: https://www.gonitro.com/support/downloads Let me know if you're still not seeing it then. Thanks! Share this post Link to post Share on other sites
Francesco 0 Report post Posted July 16, 2019 Hi Steven, thanks for your reply. I've downloaded again Nitro 12 yesterday. My complete version is 12.16.3.574. But I don't see the pop-up and icon you said. With other signed documents I see, in Nitro Pro 12, the pop-up and the icon on the left (signature pane) but not with some particular docs (that, as said, results signed with all other PDF readers and online test tools). This is a PDF signed with a certificate in a smart card (Italian CNS) in PaDES format. If you can give me a chance I can send you a document as example. Thanks again!
