    Dungeon Defenders 2 - Packet Encryption?

    Dungeon Defenders 2 - Packet Encryption?
    Hey guys,
    I've started to work on a emulator for dungeon defenders 2, since this game for myself had took the attention to start my first emulator. As far right know ive managed to emulate the whole login and authentication to get into the main menu of the game. (login stuff works through http post) I've also the ability to tell the client to which server he should connect. After coding a winsock hook for send and recv I came to the conclusion that the buffer size are most just 2 bytes.

    I started a debugger and tried to traceback the function to see where the buffer is getting encrypted but i end up in nothing to read and no function calls i can see an encryption. (but i believe the packets are encrypted)
