bcrypt FAQ
What is bcrypt?
bcrypt is a password hashing function based on the Blowfish cipher. It includes a built-in salt and a configurable cost factor that makes it intentionally slow.
How many rounds should I use?
10-12 rounds is recommended for most applications. Each increment doubles the computation time. Aim for ~250ms per hash on your target hardware.
Is this tool secure?
All processing happens in your browser using the bcryptjs library. This tool doesn't store what you enter or send it to a server.
Can I use this in production?
This tool is for testing and learning. For production, implement bcrypt directly in your application using a trusted library like bcryptjs (Node.js) or passlib (Python).
