Hi, Although this is not an iText issue per se, I am hoping that members of the iText community may have some experience to share on the subject.
I have a Verisign code-signing certificate that I am using (with iText) to sign documents in a web application. The particular certificate authority that Verisign issues their code-signing certs from is not one that is automatically trusted by Adobe Reader - in fact it seems like only the Adobe root certificate is trusted by default - so we have included instructions for our end users to set their Adobe Readers to import and trust Verisign's root certificate and to validate all signatures upon opening the PDF. Strangely, Adober Reader seems to be very inconsistent in when it validates. Most of the time, if a user has trusted our certificate chain, when they open or print a PDF signed by our web app, the signature fields validate and display a green checkmark. But sometimes, the Reader doesn't validate, and the end user sees a yellow question mark or the text "Validity Unknown". This confuses our users and makes them distrust our web application's security. Do other people have a similar experience with Adobe Reader and third-party certificates? Is there a way to force the Adobe Reader to properly validate all the time? How have other developers dealt with this issue?
