Package: qpdf
Version: 5.1.2-2
Severity: normal
Dear Maintainer,
The syntax for performing an AES cipher on an unencrypted source PDF
is this:
$ qpdf --encrypt usrpw ownrpw 256 -- source.pdf encrypted.pdf
It executes without error, but both evince and okular fail to open the
PDF using either password.

This is not a qpdf bug. This is because evince and okular do not yet
support the newer encryption format that uses 256 keys. Try it out with
a recent Adobe Reader, and you'll see what I mean. I'm not sure if any
Linux PDF readers support the newer encryption format at the moment.
Note that if you receive an encrypted file with 256-bit keys that evince
or okular can't open, you can use qpdf to decrypt or re-encrypt the
files so that evince or okular can open them.
