There is software like this around the Internet..
If someone wanted to crack your password protected PDF, for whatever reason, it is possible.
Just wondering if there is anything to prevent this besides the encryption that Adobe provides? Any additional programs or added plug-ins to strengthen encryption?
I can't seem to find anything with a quick search...
Maybe make a really strong 36 character password might render a brute force or dictionary attack useless despite the software that is used to decode it..
And, here is where it gets a little strange..
From the Labonal Blogspot..
"Legal Issues: - you maybe surprised to learn that these PDF password cracking software are absolutely legal and Microsoft even awarded ElcomSoft a Gold Certified Partner status"
Better make sure that at the very least, you have a very, very, strong password..
