John The Ripper In Kali Linux

[Crispina Blomker]

Sothe first time you run the latter, it will show the password on the screen, after which point, it will save it into a file called john.pot. In my case, the folder john.pot was located at /home/kali/.john/john.pot.

John the Ripper can retrieve the password using one of two methods: the dictionary attack or the bruteforce attack. A file with a list of potential passwords is compared to the hash at hand in a dictionary attack. If a match is found, it will chuck it out. On the other hand, if a password is not found, you can use a different password file or use a different method.

John the ripper will use its own wordlist located in the /user/share/john/password.lst to crack the password.you can also locate all the wordlists in your system by typing the following command:

$locate wordlist
