Frequently Asked Questions
What is a JWT token?

JSON Web Token (JWT) is a compact, URL-safe means of representing claims to be transferred between two parties. It consists of three parts: header, payload, and signature.

Is it safe to generate JWTs here?

Yes! All JWT generation happens locally in your browser. Your data never leaves your device, ensuring complete privacy and security.

What algorithms are supported?

Currently supports HMAC algorithms (HS256, HS384, HS512) for symmetric signing. RSA and ECDSA support coming soon.
