Greetings Andreas Hello all, I'm testing the digital signature capabilities of iTextSharp and came across this problem: when adding the ocsp response to the authenitcatedAttributes of the Pdfpkcs7 object, the signature seems to become invalid according to Acrobat (9 Pro).

Your article helped me a lot. Introduction, in this article, I will present a simple source code allowing you to digitally sign a PDF document and modify its metadata. Again; I am not an expert in signing anything. Still grepping through log files to find problems?
