JSON Web Token is an access token that is used to assert some claims. This token is verified by signature using public and private keys. JWT is based on a RFC standard, but the signature algorithm may vary between implementations.
JWT can be used to authorize a request to WeldEye, but does not provide any benefit compared to a Basic HTTP authentication.
To use JWT with WeldEye, WeldEye must know the public key to verify the JWT with and provide user identification within the claim.
