Frequently Asked Questions & Guide
What is bcrypt?
Bcrypt is a password-hashing function designed by Niels Provos and David Mazières, based on the Blowfish cipher. It is designed to be slow and computationally expensive to protect against brute-force attacks.
Why is the cost factor important in Bcrypt?
The cost factor determines the number of hashing rounds (specifically 2^cost rounds). Increasing the cost factor by 1 doubles the calculation time, making it harder for attackers to guess passwords using dictionary or brute-force attacks.
Are my passwords secure using this online tool?
Yes. All computations, including salt generation, password hashing, and verification, are executed completely client-side in your web browser. No data is sent to our servers.
