This is just a glorified brute force password cracker. The limitations are your machine. The more complex the password, the longer it will take, including YEARS.

I ran the program on a pdf, the password I know is 8 capital letters, after 3 hours nothing, I turned it off

If your password is one character, then there are 26 possible combinations. If your password is two characters, then there are 26x26 combinations - 676. This goes up exponentially, so for a ten character password, thats 26x26x26x26x26x26x26x26x26x26... 141,167,095,653,376 combinations. Yes, its going to take a while to test all those. Thats assuming you use just upper or lower case. If you used both, then its 52x52x52x52.... etc. With 15 'additional' symbols (£$%&, etc) thats 67x67x67x67x67.... etc. 1.822e+18 - so 1 with 18 zeroes. Thats gonna take a while.

Of course this is just for when you forget your own password.

rww,
I have used another of those programs, Wow Tron PDF Restriction Remover (obtained here) for a legitimate application. I own software books with CD-ROMs. Big fat books, complete with screenshots, tables and notes. The pdf of the book is on the CD, and I read alternatively the paper books and the ebook.
However, some of those pdfs are write-protected. This means I cannot annotate the ebook with my own comments and links. Imagine buying a paper book and not being allowed to write in the margins ! This is unacceptable for a technical book. It dramatically reduces its learning ability.
Wow Tron PDF Restriction Remover allowed me full legitimate use of those books I have bought. And it does not try to brute-force the passwords : it just removes them. Instantly.

Does it work with accented letters like æ or β?
Man, the captcha makes me sick...
