Node-red node for sign and validate JWT tokens.
- Sign msg.payload, msg.topic or msg.token using HS* or RS* algorithms.
- Validate msg.payload, msg.topic, msg.token, req.headers.authorization or access_token var using HS* or RS* algorithms.
- Handle certs better;
- Validations;
- Better UI.
This flow starts with injecting an RSA Private Key and Public Key each to a file (within node-red).
The Sign and Validate node will trigger a JWT claim to be signed using the Private key above (debugging the signed token), and then validating it with the matching Public key (debugging the validated JWT payload)
