Frequently asked questions
Which cost should I use?
10-12 for typical web apps. Each +1 doubles the time, so pick the highest your server can afford per login.
Why is the hash different every time?
bcrypt adds a random salt, which is stored inside the hash, so the same password never gives the same hash.
Is there a password length limit?
Yes. bcrypt only uses the first 72 bytes of a password.
