      "uid": "14f3b64bbc0c46568736731b78442500",
      "username": "ctf"
    },
    "service": {
      "hostname": "coinbase.appspot.com",
      "protocol": "https:"
    },
    "type": "web_service_binding",
    "version": 1
  },
  "ctime": 1562540064,
  "expire_in": 157680000,
  "prev": "debfd629aa8e761e1407fa5199ae047ee2a230ddbb072399e899d880a614796e",

}

which yields the signature:
