In The original DarkBasic Pro, there is an option to encrypt your bitmaps / other data, so that users wont be able to load / edit them. Has anyone come up with a method of doing this with DarkGDK?

Use RSA, save your information serialized into a bin file RSA encrypted. Easily done in .Net

Why would you want to use RSA? Why not just use symetric encryption. RSA is an asymetric encryption system which ideally should be used for transport of client to server information.

Use Blowfish or something that's fast.

Explain further... using examples in the room!

I've got some bitmaps. I have lines which say;

dbLoadImage("x.bmp",1);

However, if I want to encrypt them, I presumably need to unencrypt them in code before I call the above function, perhaps to some temporary location?
