Password Cracking – John The Ripper | Introduction and Installation

Hello World and welcome to pwnhub, the game’s afoot and in this post, I’m going to be talking about my favorite password-cracking tool, John The Ripper. John is a multi-platform password cracking tool that can crack various password hashes. It was developed by OpenWall and was initially released in 1996. I believe John got its name from another hacking tool called Jack The Cracker, or Cracker Jack. Anyway, you’re not here to read a reworded Wikipedia article.

Installing John The Ripper

John should come preinstalled on most penetration testing Linux distributions. However, your package manager may have it if your distribution didn’t come with it preinstalled. For Debian-based distributions you can run:

sudo apt-get install john
