About this Tool
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 an adaptive cost factor that makes it resistant to brute-force attacks. The cost factor (work factor) determines how computationally expensive the hash is - each increment doubles the time required, making bcrypt future-proof as hardware improves.
