What's more, if I'm not wrong, encryption depends on the reader having support, so you can effectively render encryption useless by using a very old reader and PDF format. Even GhostScript lets you bypass encryption, though not intentionally. It's really all about preventing frequent abuse of documents by lay people. Someone with the intent _will_ get your text somehow or another. There are many tools that person could employ. -- GPG/PGP ID: C0711BF1
