Library for password protecting PDF from copying, editing and printing (not viewing)

I'm looking for a good and lightweight library (preferably C or C++) to password protect PDF files from copying, editing and printing. Preferably free or cheap commercial variant, since i want library only to use this functionality. Thanks in advance.

+1  A: 

Have a look at the Haru Free PDF library. The examples suggest setting permissions should be possible.

Thank you for the effort, but this library doesnt seem to support existing PDFs. I voted you up anyway.
