FAQ
How do I generate a bcrypt hash for free?
Enter a password and a cost factor and this page produces a salted bcrypt hash — on your device with no upload, which is the only safe way to hash a real password.
Is my password uploaded anywhere?
No. Hashing runs entirely in your browser and nothing is transmitted or stored, which you can verify by turning off your Wi-Fi.
What is the cost factor?
The number of rounds; higher is slower and more resistant to brute force. 10–12 is a common choice for web apps.
Can it verify a password?
Yes — switch to verify, paste the stored hash and the password, and it tells you whether they match.
Limits
Generates and verifies bcrypt hashes; it does not store or manage them.
