How to Use JWT Encoder & Signer

About this tool

Create an HMAC-signed JWT from JSON payload data and a supplied secret.

How to use JWT Encoder & Signer

1. Select HS256, HS384 or HS512 and enter a valid JSON payload.
2. Use the iat and exp helpers if appropriate, then enter a test secret and indicate whether it is Base64 encoded.
3. Copy Signed token and inspect it in your test environment.

Worked example

Create a token with a fictional subject and short expiry for a local authentication test.

Does this support RSA or elliptic-curve signing?

The available controls support the listed HMAC algorithms. They do not provide asymmetric-key signing.

Should I use a production signing key here?

Use test secrets. A live signing key grants significant authority and should stay within your controlled signing infrastructure.
