Encryption algorithm for PIC microcontroller

Question

I'm going to perform an encryption algorithm on the PIC18f2550 and I've chosen the DES and AES algorithms. I've never worked with a microcontroller before and am not sure how I would go about this.

Do I need to write a program for it or source it from somewhere?

If I want to write How to write a program for PIC with C and do you know of any educational materials for this?

Please let me know the best way to make a start on this.

Answer 1

There are C compilers here (you need XC18) working with the MPLAB X IDE. Here you can find the libraries. You need to download the "TCP/IP Stack" library. Inside this library you can find the C code for AES algorithm for several PIC series (PIC18 as well).
