XexRetail v1.0


This tool only works with retail xex files compressed in a certain form.
I suggest using one of the following freely downloadable files:

http://assets.xbox.com/en-us/backwardcompatibility/default.zip
http://download.microsoft.com/download/5/8/a/58a10dbc-9445-4eed-83d5-22f8ad8ee855/default.zip

(you must of course extract the default.xex from these zips)


This tool attempts to brute force guess the Xbox360 Retail Xex AES key.
This key is required to decrypt retail xex files, and so would
be nice to have :)

The chances of finding this key are very slim. There is a
1 in 2^128 chance that this tool will correctly guess the
AES key. This is also assuming that the algorithm is the
same as is used for devkit crypted xexs. These aren't very
good odds, but hey you can't win the lottery if you don't
buy a ticket!

The more people that run this tool using the spare cycles
on their cpu, the better chance there is that it may be found.
If found the key is both printed to the console and saved to
a file XexRetail.key in the same directory as the exe file.

If anyone finds the key, please pass it on to those in the know
so that the people that can use this key have it.

:)
