Build and sign JWT tokens from header and payload JSON. Enter your claims and secret key to generate a token.
Edit the header and payload JSON in the input panels. The header should contain the algorithm and token type. The payload holds your claims such as subject, name, and expiration. Enter a secret key, select the HMAC algorithm, and click "Encode". The generated JWT token will appear below, color-coded by its three parts: header (red), payload (purple), and signature (blue).
