In this video on John the Ripper, we will learn how this powerful password auditing tool works through practical hands-on demos.
John the Ripper is widely used by cybersecurity professionals to test password strength in authorized environments. In this tutorial, we will first understand what a password hash is and how it is different from a plain-text password. Then, we will create our own sample passwords, convert them into hashes, and use John the Ripper to recover them using wordlists, rules, mask attacks, and different cracking modes. We will also understand why weak passwords are easy to crack, why strong password practices are important, and how tools like John the Ripper help security teams identify password-related risks before attackers can exploit them.
