FAQ
What is Bcrypt?
Bcrypt is a hashing algorithm designed specifically for password storage, based on the Blowfish cipher. It has built-in salt to prevent rainbow table attacks and uses a cost factor to slow down computation, resisting brute force attacks.
What cost factor should I use?
Recommended setting is 10-12. Each increase of 1 doubles computation time. Modern hardware suggests at least 10, high-security scenarios can use 12-14.
What's the difference between Bcrypt and MD5?
MD5 is a fast hash suitable for file verification but not password storage. Bcrypt is designed for passwords - slow computation with built-in salt, effectively resisting brute force and rainbow table attacks.
Can generated hashes be used in production?
Hashes generated by this tool follow standard format and can be used in production. Ensure passwords are transmitted over HTTPS in production.
