I have written an essay that is to be distributed digitally. In order to prevent people to copy parts of text or rip pictures, i would like to release it as an encrypted PDF file.
Really... i'm not that daft to think this kind of encryption is flawless. I'm quite guilty of crackign PDF files myself, which genarally is a piece of cake.
I'm more thinking of this encryption as a little discouragement for people to rip my work.
Anyway... i do not have Acrobat. I create my PDF files using PrimoPDF, so i will be needing some other (free) tool to encrypt my files. I have been searching around a little, and actually found a few tools that will do the trick. Problem with most of them however is, they are quite limited. Especially the number of pages a file is allowed to contain appears the problem.
