      Hi Guys,



      I am facing an issue while validating a digital signature. I applied a certified signature with “Annotation, form fill-in, and digital signatures” and then applied Redaction “find and permanently remove” a text. If I verify this digitally signed PDF in Adobe 8, it verifies where as Adobe Acrobat 9 and 10, 11 readers complains that signature is invalid.


      Investigating further I found that Adobe Acrobat is applying Redaction in append mode and the original content of signature remains unchanged after Redaction.Can someone let me know what should be the correct behavior? Why Adobe Acrobat 9 and 10 + 11 failing to verify the signed PDF where as Adobe 8 can.
