よくある質問

What cost factor should I use?
Cost 10-12 is common. Higher values are more secure but slower. Benchmark on your hardware — aim for ~250ms per hash.
Is bcrypt better than PBKDF2?
bcrypt has built-in salt and is resistant to certain attacks. Both are acceptable; choose based on your application's requirements.
