About JWT: JSON Web Tokens (JWT) are an open standard (RFC 7519) for securely transmitting information between parties as a JSON object.
Enable signing mode and provide a secret (for HS* algorithms) or private key in PKCS8 PEM or JWK format (for RS*/ES* algorithms) to edit the payload and generate a new signed token.
