简单的对图片进行加密与解密

简单的对图片进行加密与解密

//图片加密
public static void encryptionPicture() throws IOException {
    FileInputStream fis = new FileInputStream("C:\\Users\\xxx\\Desktop\\exercise\\IMG_3501.JPG");
    FileOutputStream fos = new FileOutputStream("C:\\Users\\xxx\\Desktop\\exercise\\IMG_3500.JPG"); 
    int s;
    while((s=fis.read()) != -1) {
        fos.write(s^123);
    }
    fis.close();
    fos.close();
}

对图像的解密就是将你加密的规则进行重新运算一遍

//图片解密
public static void decryptPicture() throws IOException {
    FileInputStream fis = new FileInputStream("C:\\Users\\xxx\\Desktop\\exercise\\IMG_3500.JPG");
    FileOutputStream fos = new FileOutputStream("C:\\Users\\xxx\\Desktop\\exercise\\IMG_3503.JPG"); 
    int s;
    while((s=fis.read()) != -1) {
        fos.write(s^123);
    }
    fis.close();
    fos.close();
}
