Security Tools Calculator
Comprehensive security calculator for password strength analysis, entropy calculation, crack time estimation, and hash algorithm comparison. Essential for security-conscious users and developers.
Step 1 of 4
How to Use This Calculator
- Select Tool Type: Password Strength Analysis to evaluate an existing pattern, Password Generation Parameters to design secure credentials, or Hash/Encryption Info to compare algorithms.
- For strength analysis, set the Password Length and toggle the character types you use (Lowercase, Uppercase, Numbers, Symbols).
- Review the Entropy (bits), Strength Rating, and Time to Crack for both online (throttled) and offline (GPU) scenarios.
- For generation parameters, set your Target Entropy in bits (80+ for high security) and Preferred Length to see which charset and minimum length meets your goal.
- For hash info, select an algorithm (MD5, SHA-1, SHA-256, SHA-512, bcrypt, Argon2) and check Security Status and Recommended Use before implementing.
- Use the crack-time comparison table to see the impact of attack speed on password security.
