crack packet encryption--2

hi, Im looking for someone who got knowledge with c++ and reverse engineering. Im want to create a server for a game which is down. But I dont know how to do successful handshake with the client. The server is ready just need someone who can creack the packet encryption and success at the handshake. The handshake is needed so client starts to accept and send packets. Your work: - Find out(crack) the packet encryption in the client - Create a successful handshake client<->server -OR- - Change the packet encryption by using a DLL file. - Create a successful handshake client<->server source code for the server is available but not client.
