About John the Ripper
John the Ripper is a fast password cracker, currently available for many flavors of Unix, Windows, DOS, BeOS, and OpenVMS. Its primary purpose is to detect weak Unix passwords. Besides several crypt(3) password hash types most commonly found on various Unix systems, supported out of the box are Windows LM hashes, plus lots of other hashes and ciphers in the community-enhanced version.

- Before we go on ripping and testing how strong this password is, John works with files i.e. works with file with the hashed password inside, so we are going to copy that returned line and place in a file
- Now lets give John job to do by directing it to dehash password in the test_pass file
Taking some minutes this returns something similar to
As we see it dehash the password here password (test) so easily 🙂
John might take minutes, hours, days or even weeks to dehash a password depending on how strong they are. Apart from user passwords, John also dehash hashes but must be in a text file and in this format
Summary:
For me, John is a cool tool for testing how strong your password is. Weak passwords as we used as an example here is being cracked within minutes but strong ones might take hours and might not yeild result.
