partKey := key.DerivePartKey(uint32(partID))
	return EncryptSinglePart(r, ObjectKey(partKey))
}

// DecryptSinglePart decrypts an io.Writer which must an object
// uploaded with the single-part PUT API. The offset and length
// specify the requested range.
func DecryptSinglePart(w io.Writer, offset, length int64, key ObjectKey) io.WriteCloser {
	const PayloadSize = 1 << 16 // DARE 2.0

```

### Step 3: Test with Thumbnailer

We used [Thumbnailer](https://github.com/minio/thumbnailer) to listen for MinIO notifications when a new JPEG file is uploaded (HTTP PUT). Triggered by a notification, Thumbnailer uploads a thumbnail of new image to MinIO server. To start with, download and install Thumbnailer.

```
git clone https://github.com/minio/thumbnailer/
npm install
```

if err != nil {
 log.Fatalln(err)
}
log.Println("Uploaded", "my-objectname", " of size: ", n, "Successfully.")

        String darkOff = MessageUtils.isColorEnabled() ? ANSI_DARK_RESET : "";

        String action = (event.getRequestType() == TransferEvent.RequestType.PUT ? "Uploaded" : "Downloaded");
        String direction = event.getRequestType() == TransferEvent.RequestType.PUT ? "to" : "from";

        TransferResource resource = event.getResource();

     */
    public static final String ROLE = "admin-plugin";

    private static final Logger logger = LogManager.getLogger(AdminPluginAction.class);

    private static final String UPLOAD = "upload";

    @Override
    protected void setupHtmlData(final ActionRuntime runtime) {
        super.setupHtmlData(runtime);

## Enabling Parquet Format

Parquet is DISABLED by default since hostile crafted input can easily crash the server.

If you are in a controlled environment where it is safe to assume no hostile content can be uploaded to your cluster you can safely enable Parquet.
To enable Parquet set the environment variable `MINIO_API_SELECT_PARQUET=on`.

## Example using Python API
