What's the best way to encrypt a lot of large images?

I need to encrypt a large number of large jpegs.

Photos are very sensitive and only need to be decoded in my application.

Due to the number and size of images, speed is an issue.

It doesn't matter what format your files are in - you can encrypt any sequence of bytes.

Read the documentation on, say, TripleDESCryptoServiceProvider , which will give you all the tools you need to encrypt.



Of course, if it's TripleDES

too slow for you, you can try a weaker algorithm. But to be honest, you usually trade speed for safety in these matters.
