    Problem in Verifying PDF Long Term Signature

    Israr Iftikhar Level 1




      I'm having a problem in verifying PDF Long Term Signature ( Embedded Revocation Information i.e. CRLs and Embedded TimeStamp) using Acrobat Reader. I'm using CDS Test Certificate for signing the PDF. Revocation Information and Timestamp token is embedded and viewable within Adobe Reader. I tried to verify this signature on different versions of Adobe Reader (8 and 9) but failed to verify.


      Adobe marks this signature as INVALID but when I verify this long term signature using Nitro Professional, iText and another third party application, all these applications able to verifiy this signature and also mark it as VALID.


      I'm unable to dig out the area where the problem is. I've attached the signed PDF document for your review.


      I'm waiting for your effective response.
