Cracking Passwords Guide

This document is for people who want to learn to the how and why of password cracking. There is a lot of information being presented and you should READ IT ALL BEFORE you attempted doing anything documented here. I do my best to provide step by step instructions along with the reasons for doing it this way. Other times I will point to a particular website where you find the information. In those cases someone else has done what I attempting and did a good or great job and I did not want to steal their hard work. These instructions have several excerpts from a combination of posts from pureh@te, granger53, showsgeek, PrairieFire, RaginRob, stasik, and Solar Designer. I would also like to thank each of them and others for the help they have provided me on the BackTrack forum.
