About Bcrypt

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 an adaptive cost factor that makes it resistant to brute-force attacks by increasing computation time. The cost factor determines how many iterations (2^cost) are performed, with each increment roughly doubling the computation time.
