Password Strength Lab
Estimate cracking time and analyze password strength based on charset, length, and attacker capabilities.
All analysis happens locally in your browser. No passwords are ever sent anywhere.
Hashrate Reference
GPU (RTX 4090)
- MD5: ~164 billion/s
- SHA-256: ~22 billion/s
- bcrypt (cost 5): ~184K/s
- bcrypt (cost 12): ~1.4K/s
Recommendations
- 80+ bits entropy minimum
- Use slow hashes (bcrypt/argon2)
- 14+ chars with mixed charset
- Passphrases beat complexity
