Hello Andreas, There is the PDFSigned with XFA and the XML. I also add the original document and the original document signed by adobe if this can help.
Please note that we had manualy insert the checksum in the xml we took this checksum from and XML result of an adobe succesfully signed pdf. Just to valid if this is working with the checksum because we see that the XML is the same as the Non-Signed version but without the checksum at the end. There is the document, By the way im working with mathieu on that problems its why I reply to this post ! I will continue investigate Cheer's, Christian Leclerc. http://old.nabble.com/file/p27378127/signedWithXfa.pdf signedWithXfa.pdf http://old.nabble.com/file/p27378127/signedWithXfa.pdf.xml signedWithXfa.pdf.xml http://old.nabble.com/file/p27378127/original_signed_with_adobe.pdf original_signed_with_adobe.pdf http://old.nabble.com/file/p27378127/original_unsigned.pdf original_unsigned.pdf Andreas Kuehne-2 wrote: > > Hi Mathieu, > > does your XML validate ? > How did you apply the XML signature ? > Could you share the XML document / the PDF ? > > Greetings > > Andreas > > > > > ________________________________ > From: Mathieu Fortin <mathieu.for...@notarius.com> > To: itext-questions@lists.sourceforge.net > Sent: Mon, January 25, 2010 11:04:31 PM > Subject: Re: [iText-questions] Xfa signature > > Xfa signature > Still unanswered.
