I'm practicing with John the Ripper password cracker and right now I try to crack a password from a zipfile. I wonder if it's possible to add a rule saying: password must contain this string eg. "chiCKen" so that it will try all combinations but try the exact string "chiCKen" everywhere.
So that it will be like (where a = variable)
chiCKenaaaaaa
achiCKenaaaaa
aachiCKenaaaa
ect.
I tried searching the community resources, but I couldn't find it. If you know any other password cracker that can do this, that advise is also welcome.
Thank you
