Xbox Live HDD-check ... code signature verifying
>> From readme:
[QUOTE]
xboxlive2.bin is the new HDD change-detecting code, whose disassembly was released by SmartXX. You can disassemble it again to verify that it is the same as what SmartXX released yesterday.
sigcheck.c checks the signature on the file. It can be compiled with something like this in Linux or Cygwin (the math library GMP is required):
gcc sigcheck.c -lgmp -o sigcheck
To run it, you need xboxkrnl.exe (or xboxkrnl.img) from a retail ROM. This is to remain legal - it's not a good idea to put the public key literally in a released file. The program will extract the public key from the EXE. To get this file, just use xbflash or xbtool.
./sigcheck xboxkrnl.img xboxlive2.bin
It will then tell you if the signature passed.
The reason I provided source code is so that it can easily be audited as being correct.
BTW, those looking for the XDK code that executes this: Look for places that call XcVerifyPKCS1Signature. Xbox Live games call it in two places, and one is the one you are looking for.

Download: n/a (contains some MS xlive code ... get it from the 'usual places')
Note: For those who didn't believe the disassembled code released yesterday was real, this should give them the proof they asked for.
Note that at this moment I can't say yet if Microsoft is banning people based on their HDD. There are lots of theories and ideas about what Microsoft does or will do with this HDD-information and only the future will tell. At this moment many people with large HDD inform us they are still on LIVE while a few also told us they got banned. More soon ...
