Password crackers are tools designed to recover passwords from password-protected files, systems, or accounts.
They use methods like brute force attacks, dictionary attacks, and rainbow table attacks to guess or retrieve passwords.
Password crackers are used by security professionals and penetration testers to assess password strength and identify weak credentials.
Key concepts include brute force attacks, dictionary attacks, hash cracking, salting, and ethical use in security testing.
Examples of password crackers include John the Ripper, Hashcat, and Hydra.
It's important to use password crackers ethically and responsibly, as they can be misused for unauthorized access and cybercriminal activities.
