There are several methods to do this, mask mode john passes.txt -mask=password?d?d That will use the word "password" and add 00-99 to the end of the word "password", do the opposite to add digits to the front "?d?dpassword" See the MASK file in the doc's folder to see more examples. wordlist mode john passes.txt -w=words.txt -rules=all That will use every word listed in words.txt and run every rule john has built-in. See the RULES file in the doc's folder. known force (external) mode john passes.txt -external=knownforce Knownforce is found in john.conf and you'd have to configure it to the part of the password you do know. I believe this may be the slowest method, but can do the job. Most of the suggestions if not all of them, require the latest version of John, found on GitHub. -rich
