Frequently Asked Questions

Are tokens cryptographically secure?

Hex and base64 draw from crypto.getRandomValues (suitable for secrets); the alphanumeric path picks via Math.random — use hex or base64 for anything security-critical. The readout shows entropy bits per token (a 32-char hex token reports 128 bits).

Which format per use?

Hex for database keys and debugging readability; base64 for compact tokens; alphanumeric where symbols break parsers.

What length is safe?

256 bits (32 bytes) minimum for secrets — 128 bits acceptable for non-critical IDs. Longer costs nothing; default high.

Are tokens uploaded?

No — generation runs locally in your browser via Web Crypto. Tokens never leave your device — copy them straight to vaults.
