Cracking, John the Ripper, Passwords

How to crack passwords with John the ripper

John the Ripper – is free and Open Source. You can find some passwords lists: here, here and here. To provide a wordlist to john you can do it with –wordlist argument like this: –wordlist=password.lst

Suppose that you have a file passwords.txt like this:

george:827ccb0eea8a706c4c34a16891f84e7b

thanos:202cb962ac59075b964b07152d234b70

If you have installed john already, issue the folowing command to start the brute forcing procedure:

john passwords.txt

You will get an answer like this from john:
Loaded 4 password hashes with no different salts (LM DES [128/128 BS SSE2-16])
and then nothing else. But john is working..
