Scoring
Scored based on password length, character variety, information entropy, and search space. Longer passwords with more character types have higher entropy and longer crack times. Common passwords, repeating sequences, and keyboard patterns lose points.
Crack Time Estimation
Estimated from the search space and attack speed: online attack (1K/s), offline attack (1M/s), GPU cluster (1B/s), supercomputer (1T/s). Actual time depends on hardware and algorithms.
Security Tips
Use passwords of at least 12 characters; mix uppercase, lowercase, digits, and special characters; avoid common passwords, repeating sequences, and keyboard patterns. Passwords are analyzed locally and never uploaded.
