Frequently Asked Questions

Which encoding should I choose?

Hexadecimal is widely compatible, Base64 is more compact and Base64URL is suitable for URLs and cookies.

How long should a secure token be?

The required size depends on its purpose. A token containing at least 128 bits of random entropy is common for many security-sensitive uses.

Are the tokens generated securely?

Yes. The tool uses cryptographically secure random values provided by the browser.
