如何加密图片以使其显得混乱？ [英] How to encrypt a picture so that it appears confused?

问题描述

您好

我想加密图像，使其成为未更改或更改其标题的图像文件

但我有加密问题图像没有打开，我希望它打开，但条件是它很混乱





任何人都可以用适当的方式帮助我代码，这是一个加密代码，而不是图像处理



我尝试过：

 //此代码由算法DES使用

 pictureBox1.Image = image; 
 MemoryStream ms = new MemoryStream（）; 
 image.Save（ms，System.Drawing.Imaging.ImageFormat.Jpeg）; 
 
 byte [] bytes = ms.ToArray（）; 
 BitArray bitArray = new BitArray（bytes）; 
 for（var x = 5000; x< 9000; x ++）
 textBox1.Text + = Convert.ToInt16（bitArray [x]）; 
 MD5CryptoServiceProvider mds = new MD5CryptoServiceProvider（）; 
 // UTF8Encoding utf8 = new UTF8Encoding（）; 
 TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider（）; 
 //tdes.Key = mds.ComputeHash（utf8.GetBytes（textBox1.Text））; 
 tdes.Mode = CipherMode.CBC; 
 tdes.Padding = PaddingMode.PKCS7; 
 ICryptoTransform tram = tdes.CreateEncryptor（）; 
 encrypted =（tram.TransformFinalBlock（bytes，0，（bytes.Length）））; 
 //MessageBox.Show(Convert.ToString(encrypted））; 
 File.WriteAllBytes（E：/u.jpg，加密）; 
 

解决方案

基本上，在视觉上使图像全部消息是不值得的。



加密图像几乎是不可能的，并且它仍然具有与原始图像完全相同的尺寸。要做到这一点，你将被限制为弱加密方法，导致一对一的字节，如替换密码。

Hello
I want to encrypt the image so that it is as an image file that has not changed or changed its header
But I have a problem with encryption is that the image does not open and I want it to open but on condition that it is confused


Can anyone help me with the appropriate code so that it is a cryptographic code and not an image processing

What I have tried:

//This code was used by an algorithm DES 

pictureBox1.Image = image;
           MemoryStream ms = new MemoryStream();
           image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);

           byte[] bytes = ms.ToArray();
           BitArray bitArray = new BitArray(bytes);
           for (var x = 5000; x < 9000; x++)
               textBox1.Text += Convert.ToInt16(bitArray[x]);
           MD5CryptoServiceProvider mds = new MD5CryptoServiceProvider();
           //UTF8Encoding utf8 = new UTF8Encoding();
           TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
           //tdes.Key = mds.ComputeHash(utf8.GetBytes(textBox1.Text));
           tdes.Mode = CipherMode.CBC;
           tdes.Padding = PaddingMode.PKCS7;
           ICryptoTransform tram = tdes.CreateEncryptor();
           encrypted = (tram.TransformFinalBlock(bytes, 0, (bytes.Length)));
           //MessageBox.Show(Convert.ToString(encrypted));
           File.WriteAllBytes("E:/u.jpg", encrypted);

解决方案

Basically, it's not worth the effort to make the image "all message up" visually.

It's virtually impossible to encrypt the image and have it still have the exact same dimensions as the original image. To do that, you'd be limited to weak encryption methods that result in a one-for-one byte, like a substitution cipher.

I will shorten my question all I wanted to show me the picture after the encryption like this
