I currently interested in pen testing and want to experiment on cracking wifi hashes. The problem is that laptops are not very good when it comes to cracking hashes so, I decided I could offload to my desktop. The problem is that is there any programs that will allow me to remotely access my desktop(running windows 8.1)? If there is a program that could do that does my desktop have to be on or can it start it up remotely?
