Java BufferedImage write / read (different rgb values)

I wrote an image with this code:

BufferedImage newImage = new BufferedImage(width, height, BufferedImage.TYPE_3BYTE_BGR);
index = 0;

for (int i = 0; i < height; i++) {
    for (int j = 0; j < width; j++) {

        int r = ciphered[index++];
        int g = ciphered[index++];
        int b = ciphered[index++];

        Color newColor = new Color(r, g, b);
        newImage.setRGB(j, i, newColor.getRGB());
    }
}
File ouptut = new File("/Users/newbie/Desktop/encrypted.jpg");
ImageIO.write(newImage, "jpg", ouptut);

When I try to read the image ("encrypted.jpg") I get different RGB values. I read the image with the following code:

File input = new File("/Users/newbie/Desktop/encrypted.jpg");

BufferedImage image = new BufferedImage(512, 512, BufferedImage.TYPE_INT_RGB);
image = ImageIO.read(input);
int[] t = new int[width * height * 3];

for (int i = 0; i < height; i++) {
    for (int j = 0; j < width; j++) {

        Color c = new Color(image.getRGB(j, i));

        int r = c.getRed();
        int g = c.getGreen();
        int b = c.getBlue();

        t[index++] = r;
        t[index++] = g;
        t[index++] = b;
    }
}

I don't understand what I'm doing wrong. I just get different rgb values from the ones I've inserted.
