My friend Johnny

First we will talk about my friend Johnny. Johnny is a GUI frontend for my other friend John. For most password cracking tasks, this is an easy way to use Johnny. It uses the normal defaults for most password cracking sessions. Once you have captured some hashes, save them to a text file and open Johnny. As shown in the following image, Johnny can be found under Applications | 05 – Password Attacks | johnny:

Once Johnny is open, click on the Open Passwd File button and pick the text file where you have saved the user's hash values. This will load the file into Johnny.

Tip
