Frequently Asked Questions

Are these keys stored on your server?

Never. Key generation happens purely in your browser via JavaScript. We never see or store them.

Which format is most secure?

All formats use the same entropy valid source. Base64 is shorter for the same data, while Hex is more standard for hashes.

Can I use these for production apps?

Yes, they are generated using the Web Crypto API, making them suitable for production security needs.
