Frequently Asked Questions

Is Bcrypt Generator free?

Yes, PivaBox Bcrypt Generator is completely free to use. All hashing runs locally in your browser — passwords never leave your device.

Are my passwords uploaded to a server?

No. All bcrypt hashing and verification happens entirely in your browser using the <code>bcryptjs</code> library. Your passwords and hashes never leave your device.

How many salt rounds should I use?

For production use, <strong>at least 10 rounds</strong> is recommended. Each increment doubles the computation time, making brute-force attacks exponentially more difficult. The default of 10 rounds balances security and performance. Higher values (12+) provide stronger protection but may result in slower hashing.
