|  | JWT | 
|  | === | 
|  |  | 
|  | JSON Web Tokens (JWT) are an open, industry standard [RFC | 
|  | 7519](https://tools.ietf.org/html/rfc7519) method for representing | 
|  | claims securely between two parties.  Although JWT is fairly flexible, | 
|  | this API is limited to creating the simplistic tokens needed to | 
|  | authenticate with the Google Core IoT infrastructure. |
