How to Use This Calculator
  1. Enter the password length and character set size (or use the checkboxes for character types).
  2. Set the attacker guessing speed in hashes per second.
  3. Review the average time to crack in years at the given speed.
  4. Adjust password length to see how adding each character exponentially increases attack time.
  5. Target at least 100 years of crack time at modern GPU speeds for sensitive credentials.
