Michael, it´s very complicate to explain for you, but I will try... I have a new legal process to follow where the signed PDF document CAN BE converted to other file standard, like .P7S type. I think the P7S viewer will not show the first signatures after the conversion. So, I need to guarantee the first signatures, I don't know, I think to store the signature data, or some like that, inside other legal document in order to prove later that fisrt PDF document is autentic. Seems a crazy way but that's what I was asked to investigate.
I don't know if exist some P7S viewer or signer that can keep and show the PDF signatures (that would solve the problem). It's a new process to be implemented and I don't know yet the best way to follow. tks a lot. PS. About the byte ranges, I get it -- View this message in context: http://itext-general.2136553.n4.nabble.com/How-to-get-the-HASH-from-a-signature-tp4655996p4656004.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.
