Swat 4 CDKEY issue - Please be patient with me

[blazetech]

Hi, I owned a cyber cafe here in Malaysia and we go by a licensing sceme when it comes to games. That means we sign an agreement with the game distributor and they will send us games every month. I receive Swat 4 for January 2006 (yes it took them that long to get the game to us) and as it is a new year i am plannign a major maintainance for my cafe. How I do things is have a PC ready with all the games and updates and ghost it to the other computers. After that I'll use a keychanger I wrote with AutoIT to change the game keys in one go.

Swat 4 CDKEY stored in the registry is in REG_BINARY format. From what I have read on the internet it is encrypted. I am not trying to get you guys to give me a key coz I've already have the legit keys. Just that I don't want the hassle of installing the game manually into every pc in the cafe (I've got 60 coms over here). Is there a way of encrypting the keys that i own into how the game is doing it so that i could write it into the registry with my keychanger?
