Fallen Earth man-in-the-middle proxy

Proof of concept project that implements the Fallen Earth network cipher protocol. feproxy acts as a man-in-the-middle proxy that strips the encryption of packets in realtime for plaintext viewing and further reverse engineering.

Documentation of the network cipher was accomplished by disassembling the game with IDA Pro and following and understanding the logic handling network sockets. This necessitated a thorough understanding of C++ (what the game was written in) and how it translated to machine code (x86 assembly). A pseudo-C reimplementation of the logic can be found in the accompanying Reversing.md document.
