 I use qpdf to encrypt a pdf file with a 256 bit key:  
qpdf --encrypt pwd pwd 256 -- in.pdf out.pdf
When out.pdf is opened with qpdfview, it requests the password, then fails, reporting "Could not open out.pdf" (gui) or "Error: Incorrect password" (command line).    out.pdf can be opened in firefox.

Files encrypted with 128 or 40 bit key are opened with no problem.  Should qpdfview be able to open files with 256 bit encryption?  Thanks.
