> This patch adds support for decrypting files using the (deprecated) AES-256 scheme revision 5. The current version only support revision 6. Since revision 5 files are generated by Acrobat 9, there is a relatively large amount of them in the wild so support is needed.
> This patch includes also the fixes from PDFBOX-2268
