ARC4 tutorials posted
Long overdue, I have finally completed the tutorials for ARC4 ("Alleged RC4") cryptography for use with RF wireless transmissions via the nRF24L01. Now you can secure the data that you're sending through the air in a similar format to WEP and WPA security protocols. I have created implementations in C for PIC and ARM architecture (PIC18F452 and LPC2148, respectively) just like all of the other tutorials. Now you're in the big leagues!
Check out the links to the zip files here: LPC2148 and PIC18F452.
