What is Bcrypt?
Bcrypt is a cryptographic hashing function specifically designed for securely storing passwords. Unlike older algorithms like MD5 or SHA-256, Bcrypt is intentionally slow and computationally expensive. It incorporates a randomly generated "salt" into every hash, meaning that if two users have the exact same password, their Bcrypt hashes will look completely different. This protects databases against rainbow table attacks.
Bcrypt Tool FAQ
Are my passwords sent to your server?
Absolutely not. Passwords should never be transmitted in plain text to third-party tools. Our Bcrypt utility relies on bcryptjs, a pure JavaScript implementation that performs all cryptographic hashing completely locally on your device (Client-Side).
What is the "Cost Factor" (Rounds)?
The cost factor determines how many iterations the algorithm performs. A cost of 10 means 210 (1,024) rounds. Increasing this number makes generating the hash exponentially slower. This deliberate slowness is a security feature to thwart brute-force attacks. We recommend leaving it at 10 or 12 for standard applications.
