JWT Encoder
Fill in the header and the payload, choose an algorithm, then sign the token with a secret or a key. HMAC, RSA, ECDSA and RSA-PSS are all supported, and the token is built in this tab.
Runs in your browser. The file stays with you.
Choosing “none” leaves the token unsigned. That is useful for reading the format, and for nothing else.

Fill in the key and the signed token appears here.
