    "GoogleCloudStorage" : {
        "StorageEncryption" : {
            "Enable": true,
            "MasterKey": [3, "/path/to/master.key"], // key id - path to the base64 encoded key
            "PreviousMasterKeys" : [
                [ 1, "/path/to/previous1.key"],
                [ 2, "/path/to/previous2.key"]
            ],
            "MaxConcurrentInputSize" : 1024   // size in MB 
        }
    }
}
```
