Chapter 5
John the Ripper
Now that we have covered a lot of the basic of password theory and an understanding of wordlists, let’s dig into cracking tools! In the next several chapters we will look at two of my favorites, John the Ripper & Hashcat. We saw that sometimes you can just do an online hash lookup, and in some cases, you can pass the hash. But if all else fails, you have to crack the hash. Kali includes several excellent tools to do this. We will quickly cover John the Ripper in this chapter, then dive deep into Hashcat in the upcoming chapters.
