Hash a password with bcrypt and a cost factor you choose. Free and private: runs in your browser.
Enter a password to get a salted bcrypt hash ($2b$…), ready to use as a test fixture or seed value.
Hashing runs locally in your browser. Your input never leaves this page.
Use cases
- Verify a download or file checksum.
- Create test fixtures for authentication code.
- Debug a hash mismatch between two systems.
Frequently asked questions
Which bcrypt cost factor should I use?
Pick the highest that keeps a login under about 250 ms on your servers, usually 10–12 today. Each step doubles the work.
Is the Bcrypt Hash Generator free?
Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.
Is hashing the same as encryption?
No. A hash is one-way: you cannot get the input back. Encryption is reversible with a key. Use slow password hashes (bcrypt, Argon2, PBKDF2) for passwords and fast hashes (SHA-256) for integrity checks.
