I think I already know the answer to this question, but I thought I'd ask the experts anyway.
A few months back, I created a password-protected 7-Zip archive which housed the source code of a simple program I was writing at the time. I was using the archive everyday, and so never wrote the password down. I've been racking my brain since finding the archive on my hard drive earlier in the week trying to remember the password, but I'm sure it's long forgotten.
I was wondering if there is any way to brute-force this password, or if it is even possible?
The password is at probably 4-13 chars long, and more than likely alpha-numeric with symbols too. It doesn't contain essential files, but I'd like to recover the code if at all possible.
