Understanding Bcrypt Hashing
Bcrypt is a password-hashing function designed by Niels Provos and David Mazières, based on the Blowfish cipher. It is the standard for modern password security because it incorporates a **salt** to protect against rainbow table attacks and is **adaptive**, meaning it can be made slower over time to resist brute-force attacks.
What is the "Cost" Factor?
The cost factor (rounds) determines how many iterations the algorithm performs. A higher cost makes the hash harder to crack but takes more CPU time to compute. For most modern web apps, a cost of 10-12 is ideal.
Is Bcrypt Secure?
Yes! Bcrypt is currently one of the most recommended hashing algorithms by security experts. Unlike MD5 or SHA1, it is specifically designed to be slow, making it impractical for attackers to guess passwords.
How to Use This Tool
Whether you are debugging a Laravel, Node.js, or Python application, you can use our **Bcrypt Generator** to create test hashes or use the **Verifier** to check if a password matches a specific hash stored in your database.
