  "ccType": 1,
  "ccReport": "..."
}

1. Query the CC measurement

grpcurl -authority "dummy"  -plaintext -d '{ "container_id": "29134314a2...", "index": 0, "algo_id": 12}'  -unix /run/ccnp/uds/ccnp-server.sock ccnp_server_pb.ccnp.GetCcMeasurement

The output looks like:

{
  "measurement": {
    "algoId": 12,
    "hash": "..."
  }
}
