🔐 What is John the Ripper?
John the Ripper, often abbreviated as “John,” is a fast and powerful password cracking software tool. It’s designed to detect weak passwords in Unix-based systems, but it also supports Windows, Linux, and Mac. Cybersecurity experts and ethical hackers use it to identify and fix vulnerabilities before malicious hackers can exploit them.
This tool supports a wide range of password hash types including MD5, SHA, DES, and more. John is a go-to utility when simulating attacks during network security penetration testing scenarios.
🧰 How Does John the Ripper Work?
At its core, John uses a brute-force or dictionary attack technique to attempt to crack passwords. It systematically tries all possible combinations or known password patterns from a predefined list until the correct one is found.
