Excellent, Long-Established Password Cracker.
Use Cases and Deployment Scope
We had to undertake a password auditor project recently, so one of the key performance indicators was to use a password cracker to check the veracity of the passwords. The best-known one was 'John the Ripper' so we went ahead and used it. Its main strength lies in detecting password hashes and running against the very best ones (apart from AES). The password crackers can be run from one location for convenience and this also adds to the effectiveness of the application. 'John the Ripper' mainly relies on incorporating brute force attacks and dictionary table attacks on plaintext passwords and this is where t is more effective.
