推荐答案

如果要加密图像，强烈建议您不要对每个像素进行加密.
更好的方法是将图像作为原始二进制数据处理并对此进行加密:

内容:
图片->保存到流->将流写入CryptoStream->随时随地保存CryptoStream

反之则相反.

If you want to encrypt your image, I highly recommend you not encrypting each pixel.
The better way is to handle the image as raw binary data and encrypt this:

Encrpytion:
Image -> Save To Stream -> Write Stream to CryptoStream -> Save CryptoStream wherever you want

The decryption is the other way round.

Maybe this article this article[^] can help you.

The only problem is, that you cannot display the encrypted data as image since it is (nearly random) binary data.
Maybe this[^] could help then.
