Decoding an air conditioner control's checksum with differential cryptanalysis
Nice writeup! I'm going to be decoding a variety of air conditioner remotes in the future so this will be a good reference.<p>If anyone is interested in the process of reverse engineering an infrared remote from "I have a raspberry pi and some electronics" to "I can decode and encode infrared signals to control my stuff", I have an article on that:<p><a href="https://blog.bschwind.com/2016/05/29/sending-infrared-commands-from-a-raspberry-pi-without-lirc/" rel="nofollow">https://blog.bschwind.com/2016/05/29/sending-infrared-comman...</a><p>There are better ways to do what I've described there but it's a good start.
