PDF Decrypter

Can anyone tell me where I can find a freeware or unrestricted evalution version of a program that will decrypt the permissions password on a pdf file?  I have a GBA Flash card reader that can be used to view .txt and I have several books in .pdf format that I can't convert to text because the .pdf permissions blocks editing and copying of the file.

Oh hey, it's my work, it better show it exactly like I wanted to. Why do you think so many people use PDFs if it was so inferior? It does exactly what they want it to do. And it's not all about presenting online. For example if I wanted to print a document in another computer like my Maths Research project to hand in but the computer doesn't have the application I used to write it up like LATEX, then the pdf will conserve everything. So fuck you and your elitism. gb2/linux/ with your shitty applications and gaming.
