Hi,
Hi István,

If someone is interested, here is a working sample application for
signing and timestamping (!!!) PDF with PDFBox:
Thanks for this example. It will certainly help the pdfbox community doing such special task.

I would like to port your code to the pdfbox examples. So it will be an official example for other pdfbox users. Did something from your side speak against it?

Only one problem left:
- My document is signed, but not certificated. How can I set the
certification level? (Equivalent to
appearance.setCertificationLevel(PdfSignatureAppearance.CERTIFIED_NO_CHANGES_ALLOWED);
in iText)

I don't figure this out at the moment. Maybe this setting need to be done in the appearance dictionary.

Did you maybe have an example document created with iText that containing such a property?
