Test Your Password Strength Against John the Ripper

This is a demonstration video on how to test the strength of your passwords on an Ubuntu system against the John the Ripper password cracker. It is important to know how fast these tools can actually work to crack passwords and how to protect yourself against them finding your password. In my example password, password1 and elephant were all found in under 20 seconds and I don’t have a fast machine. Btw… these were test accounts I removed immediately after making the video 🙂
