Gi, guys. My problem is that I encrypted some files with 7zip (AES-256), but I forgot the password for the archive.

As I see it, the solutions are brute forcing it with john the ripper or RarCrack. While Rarcrack is fairly easy to use, I remember a part of my password and I want to optimize the process.

Rarcrack allows you to specify the characters with which you are going to bruteforce the archive, but it does not allow you to set a starting word (as far as I know).

Let's say my password was test1234. Instead of trying with chars tes0123456789, I want to start the bruteforcing with the string "test" and then try with 0123456789.

Anyone knows a way of doing that?

You can use 7zrecover, it is easy to use and if you know what words could be in your password you will get it back pretty fast.

7z encryption is a pain ass, it is specially made to slow brute force attacks. Good luck!
