      "eldest_kid": "01202cd7d810b48b638125de97847f754159dc58f0f9857b15de538d110b4371fa9a0a",
      "fingerprint": "7655c5d2953e72e9607ae7c31a8574a923fc6c12",
      "host": "keybase.io",
      "key_id": "1a8574a923fc6c12",
      "kid": "01019274af2fee02e393a0b87584b07092f080746257cc09846a4386bbf1e384aaad0a",
      "uid": "a070de4efd2158dcda03868a6cb98319",
      "username": "zhouxinan"
    },
    "service": {
      "hostname": "xinanzhou.com",
      "protocol": "https:"
    },
    "type": "web_service_binding",
    "version": 1
  },
  "ctime": 1625106601,
  "expire_in": 157680000,
  "prev": "b887f9824360b59224141b7989e09d8b002c193594db2e4604fbfcff0007474d",
  "seqno": 34,

}

which yields the signature:
