Frequently Asked Questions
What is Bcrypt?
Bcrypt is a password-hashing function designed by Niels Provos and David Mazières, based on the Blowfish cipher. It incorporates a salt to protect against rainbow table attacks and is adaptive (you can increase the cost rounds to slow down brute force attempts).
How does the Bcrypt Verifier work?
Paste your plain-text password and the Bcrypt hash. The verifier will perform a client-side comparison using the Bcrypt algorithm to check if they match.
Is my password safe?
Yes. All computations are run entirely inside your browser using the `bcryptjs` library. No data is ever transmitted over the network.
