I have PDF files secured using 256-bit AES, requiring a password to open the file (Acrobat 9 or greater)

I can use Foxit Reader or Adobe Acrobat just fine on Windows, but I can't view those PDF's on Ubuntu or Mac OS X. What PDF readers for OS X and Ubuntu support 256-bit AES?

Here's a sample file.

I tested the sample file with Adobe Reader for OS X, and although you didn't provide a password, it did prompt for one, whereas just displayed a blank page. (And it would make sense that Adobe Reader for OS X would provide the same functionality as Adobe Reader for Windows).

Edit: I just created a 256-bit AES encrypted test PDF with Acrobat Pro on Windows, tried to open it with Adobe Reader on OS X and it succeeded.

Edit 2: I just installed Adobe Reader 9.3.3 in my Xubuntu install and it could open the same AES-encrypted PDF. As for stock Ubuntu, there is a bug for Evince (the PDF renderer) to try and get AES support.

I'm sorry, the password is "password." Can you see if it works? – NullUser Jul 21 '10 at 17:52
