John The Ripper

What is John the Ripper?

John the Ripper (often referred to simply as "John") is one of the most popular password-cracking tools in the cybersecurity field. It is designed to crack password hashes using several algorithms and cracking methods such as dictionary-based attacks, brute force, and hybrid attacks. John supports a wide range of hash types, including DES, MD5, SHA-1, and more.
