Yes I have upvoted your answers on crypto.stackexchange as I have > 15 rep there. But after all we are all humans sharing ideas, and it is because of people like you we have this amazing community in the first place! I really do believe that a sincere appreciation will do miracles for the giver as well as the receiver, and for the entire community ! I really do respect everyone at the other end, and people like you are like a beacon of light for anyone to learn cryptography or programming by their self alone ! I was always fascinated by crypto ever since I was a kid !!!
@EugeneStyer Of course, I will but I'm not using any external libraries like openssl for it. So is WPA2 PSK enough for LAN ? Can a malware running in my OS (server/client) intercept with my communication ?
