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.

I love the way it shows in every system exactly the way you want it
I love how so many people are such control freaks that when they provide information they insist it must be presented in a certain way. This is the same pathology that causes all those blogs with the horrible narrow single fixed width columns.
