The PDF specification itself recommends using external encryption in this case. From section 7.6.1 of the PDF specification: NOTE: Conforming writers have two choices if the encryption methods and syntax provided by PDF are not sufficient for their needs: they can provide an alternate security handler or they can encrypt whole PDF documents themselves, not making use of PDF security. It is very easy to defeat PDF security in any file that has a blank user password since it is just up to the application to enforce security. I've written a detailed explanation of this which I can dig up and send you if you're interested. -- Jay Berkenbilt <q...@debian.org> -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
