Guys, Learning more and searching the web, I found P7S viewers that can extract the embedded PDF file and invoke the Acrobat Reader for viewing and signature verification. I think this is enough for my problem.
Whole problem started when my customer told me about his concern that after the P7S sign process, the original document would lose the PDF signatures(no sense for me). After research, we found out that he was wrong and that we can see the first signatures without problems. I would like to thank the information and time given by you on this subject and I believe learned more after that. Thank you. -- View this message in context: http://itext-general.2136553.n4.nabble.com/How-to-get-the-HASH-from-a-signature-tp4655996p4656016.html Sent from the iText - General mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
