Bcryptジェネレーター の使い方
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.

よくある質問
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.
