I know 95% of my KeePass-db password – how can I brute force the last remaining part using rules with John The Ripper?

Hi all,

I’m trying to bruteforce the last remaining 5% of my KeePass database password using John The Ripper and I can’t seem to get the rules part to append all possible characters at the end right.

I created a test.kdbx with a known pw that should be roughly the same, got the hash extracted and I created a wordlist.lst with the part of the password that I know. I think it’s between 1 or 3 characters that followed my known password – how can I get John The Ripper to append these after my provided word?

I tried “$!” since my last character of my test-pwd is a ! but it doesn’t seem to work that way. I’m using Johnny GUI with John Jumbo 1.9 executables.

Thanks!
