Java Programming

So I'm trying to view an ecrypted image (gif). I've done the encryption part and my problem lies on reading the encrypted image since the ImageIO.read(in) method returns a bufferedImage but returns a null if its encrypted so I can't display it.

image = ImageIO.read(file);
buffimage = new BufferedImage(image.getWidth(null),image.getHeight(null),BufferedImage.TYPE_INT_RGB);
ImageIO.write(buffimage, "gif", baos);
baos.flush();
ciphertext = encrypt(baos.toByteArray()); //encrypt
baos.close();

secimage = new BufferedImage(image.getWidth(null),image.getHeight(null),BufferedImage.TYPE_INT_RGB);

InputStream in = new ByteArrayInputStream(ciphertext);
secimage = ImageIO.read(in); // returns null :(

in.close();

Is there another way of doing this? please help


Thanks
