如何在android studio中计算位图的SHA-256？

implementation 'commons-io:commons-io:2.6'
implementation 'org.apache.commons:commons-codec:1.15'

import org.apache.commons.codec.digest.DigestUtils;

public String calculateSHA256(Bitmap bitmap) {
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream);
    byte[] byteArray = outputStream.toByteArray();
    String sha256Hex = DigestUtils.sha256Hex(byteArray);
    return sha256Hex;
}

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.your_image);
String sha256 = calculateSHA256(bitmap);
