[tde-users] Re: KPDF asks for password on some PDFs

I strongly suspect kpdf has no idea how to handle AES-256 encrypted data (was likely not part of .pdf in 2005 timeframe) It may also be not handling the print:, copy:, change:, addNote: restrictions correctly either. Wherever the failure occurs it is tipping the password prompt in hopes of correcting it. xpdf, firefox, etc. have likely been updated to handle the new restrictions and encryption correctly.
