PDF

Remove PDF passwords in Ubuntu

Have you ever bought a book in PDF format, only to receive it with the annoying password protection popup? You know, the ones that come with digital downloads and/or "free" copies that escort payed hard copies, where you need to type your e-mail every single time you open them. Hey, I'm all for protecting your content and such, but this just feels like I'd get more value if I downloaded a pirated copy!
