Bcrypt Hash Generator & Verifier

Bcrypt is a password hashing function designed by Niels Provos and David Mazieres, based on the Blowfish cipher. It incorporates a salt to protect against rainbow table attacks and uses a cost factor to make brute-force attacks computationally expensive. This free online tool lets you generate bcrypt hashes with adjustable cost factors and verify passwords against existing hashes. All processing happens locally in your browser.
