Encrypt/decrypt desktop to pocket pc

I'm looking for a way to encrypt a file on my desktop computer move it to my pocket pc where it will be decrypted when I access it than encrypted again when I close out my program that opened it on my pocket pc. The file will be copied to my sd card and accessed from their that is why i want it encrypted when i move it and only decrypted when my program opens it that encrypted again when I close my program Does anyone know of a way to do this? I have a way in my mind, but I just keep getting a block when I go to code it. If anyone has some code that will help that would be great. The simpler the better. Does this make sense?

Thank you,

Matt

I'm new to some stuff in c# how do I call these functions from my c# program? Can you give quick example so I can see what I'm missing. I'm able to call them, but i'm getting errors and I'm not sure why. If I can see how you do it I should be able to find my mistake. I've tried all kinds of things and it's just not working.

Thank you for your help
