Frequently Asked Questions

What cost factor should I use for bcrypt?

A cost of 10-12 is recommended for most web applications, balancing security and performance. Cost 10 takes about 100ms per hash. Each increment doubles the time.

Is bcrypt better than SHA-256 for passwords?

Yes. SHA-256 is designed to be fast, which makes it vulnerable to brute-force attacks. Bcrypt is intentionally slow and includes a built-in salt, making it much more secure for password storage.

Can I verify a password against a bcrypt hash?

Yes. Enter the password and the bcrypt hash, and the tool will tell you if they match. The salt is embedded in the hash, so no separate salt is needed.
