Frequently Asked Questions
What is a JWT?
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 (algorithm, type), Payload (claims, user data), and Signature (HMAC or RSA). JWTs are used for authentication and information exchange.
How do I generate a JWT?
1. Choose algorithm (HS256, HS384, HS512). 2. Enter your secret key (for HMAC). 3. Add payload claims (sub, name, email, etc.). 4. Set expiration time (exp). 5. Click Generate. The token is created instantly in your browser and never sent to any server.
Is it safe to generate JWTs online?
Yes! All JWT generation happens entirely in your browser using the Web Crypto API. Your secret key and payload never leave your computer. The generated token is displayed immediately and is never transmitted or stored anywhere.
