bcrypt uses the Blowfish cipher. http://php.net/manual/en/function.password-hash.php http://php.net/manual/en/function.password-hash.php: PASSWORD_BCRYPT - Use the CRYPT_BLOWFISH algorithm to create the hash. This will produce a standard crypt() compatible hash using the "$2y$" identifier. The result will always be a 60 character string, or FALSE on failure.
