Andreas Lehmkühler commented on PDFBOX-2484:
--------------------------------------------
The encryption dictionary was't parsed recursively when using the
non-sequential parser so that the decryption doesn't work correct. My changes
ensure that everything is in place to encrypt the data so that the PDFDebugger
now works. But theres is still an issue with the PDFReader and I guess there is
maybe a similar issue with another dictionary.
I'm investigating further ...
