Using high level languages, it's not a problem of particular processor architectures.

I need just simple encryption. not and advanced one? I have to use C. Can you tell me about any algorithm and how to use it. Or where i can read about it?

Example of a random number generator seed generator using a PIC18. **broken link removed**
