How to Use Bcrypt Hash Generator

Enter a password and select a cost factor (salt rounds, default 10). Click "Hash" to generate a bcrypt hash. To verify, enter a password and a bcrypt hash, then click "Verify" to check if they match. Bcrypt is the gold standard for securely storing user passwords in databases.

Frequently Asked Questions

Why is bcrypt better than SHA-256 for passwords?+
Bcrypt is intentionally slow (thousands of times slower than SHA-256) and includes a built-in salt. This makes brute-force and rainbow table attacks impractical. SHA-256 is too fast for passwords - an attacker can test billions of guesses per second.
What cost factor should I use?+
Cost factor 10 is the standard minimum (1,024 iterations). Each increment doubles the computation time. Use 12 for higher security, 14+ for very sensitive systems. Balance security against login response time - hashing shouldn't take more than ~250ms.
