[jira] [Updated] (PDFBOX-3017) Improve document signing
[ https://issues.apache.org/jira/browse/PDFBOX-3017?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tilman Hausherr updated PDFBOX-3017:
------------------------------------
Description:
Improve signing code:
- incremental save only works for signatures and doesn't respect certificates such as Adobe Extended Usage Rights
- -{{prepareNonVisualSignature}} clears the AcroForm DR {{acroForm.setDefaultResources(null)}} which is not good if there are other form fields-
- visual/nonVisualSignature should move into the {{interactive.forms}} package and be handled within the signature field
- verify signature (to have tests that go full circle)
- document or refactor / rewrite visible labyrinthine signature code
- support rotated pages (see https://stackoverflow.com/questions/34012293/pdfbox-sign-landscape-file-error/34359956#34359956 )
- make sure that signed PDF/A files are still PDF/A (see http://www.pdfa.org/wp-content/uploads/2011/08/tn0006_digital_signatures_in_pdfa-1_2008-03-14.pdf ); /ID possibly not OK; /Annots is possibly required ([~tilman] removed this for invisible signatures); test signed files with PDF-Tools and with preflight; test whether "bad" signatures are detected by preflight
- ... your ideas...
