This is not entirely true, you can encrypt PDFs [1] since v1.3 of the spec but the cypher is often so weak (RC4 until v1.6) they can be bruteforced in reasonable amounts of time.

You can encrypt them to completely prevent them from being opened. But cgb223 wasn't talking about that, cgb223 was talking about the ability to open them but not copy text, or not print.

You can make the text uncopyable by using non-standard font indexing. The reader will be able to copy the text but it will be gobbly-gook. It forces the user to OCR the PDF or reverse the font mapping.

And ain't that a treat when clients send us PDFs to sort, print, and mail, but the address extraction fails completely.
