About Bcrypt Hashing & Cost Factors

What is Bcrypt?

Bcrypt is a blowfish-based password hashing algorithm designed to be slow and resistant to brute-force GPU hardware attacks. It automatically embeds a 128-bit salt within the generated hash string.

Security & Privacy

Your plain-text passwords and hash computations are executed 100% locally inside your browser memory. No data is stored or transmitted.
