Hello,

Tried anyone to capture XboX Live Protocol by packet sniffer like Wireshark? If yes, is it based on any cryptographic protocol? Can I host(in local network) alternative server, which be detected by Xbox as Microsoft Live server?

Regards,
Please answer ASAP.

Sorry, but I am Polish and I didn't speak English good.

Yes, people have tried.

Yes, it is signed and encrypted.

No, you can't host it yourself because it is signed and encrypted.

This question has been asked and answered many times, and should have been posted in the newbie section....

Did you know on what cryptographic protocol XboX Live is based?(like IpSec, SSL etc.)

No, but knowing the protocols and algorithms won't help you because you don't have the Microsoft private key.

And... Can I replace public key in my Xbox console to generated by me? What Filesystem is it in the xbox's flash?

No..

The poster above is not 100% correct.

Seriously, this was looked at before and the conclusion was it was not going to be possible.
The packets are encrypted with a session key that is generated during the hand shake process, there is some in the clear packets but the info they pass is limited.

You are not going to be able to reverse this.
