DayZ Arma 2 Hack

Hey guys, I just recently bought Arma 2 just to play DayZ mod. The one thing I don't like is how bandits camp the spawn and you're helpless because you start with the crappiest pistol in the game. Now to the hack part, What I want to do is to edit the mod file so when you press a button you get a better weapon. I figured this out on my own. The problem is the server uses RSA checks on the mod files. While packet sniffing the game I managed to find that the game sends a packet which includes the RSA signature of the file to the server which decides if we are allowed to connect or not. What I need to know is, is there a program that can intercept the games packets looking for a keyword in the packets then block and replace the packet from the hacked file with the packet from the clean file? That would make it look like the user is using a clean and signed file while he is actually not.
