There is... I've been digging and there is Diffie Hellman key exchange on top of something else. I'm trying to RE this, the problem i have is i don't really know how to parse the data with the key. The structure is as follows:

"header#UINT8,agreedLength#UINT16,dataLength#UINT16,data#CIPHER_KEY_DATA"

There are 2 keys as the cipher length is 256, one static and one ephemeral i think, might be wrong. So i generate 2 keys myself, send them back in the same structure as the client does, and i get nothing back, which means I've done something wrong somewhere. The cipher key data also looks weird. Any help?

Edit: Got the key agreement completed response. Don't know what's next but i'm gonna be looking into it, any help appreciated. 

I'm wondering what encryption is used to connect and communicate between the client and the server? Global servers, if there's any diffrence
