F. Schmitt commented on PDFBOX-953:
-----------------------------------
The documentation can be found here:
http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/adobe_supplement_iso32000.pdf
(Chapter 3.5 - Encryption)
The revision of the standard security handler was extended to number 5.
I would also like to see this feature. Or at least an exception, that revision
5 is not yet supported would be cool.
Thanks.
