Some one is on to something

"Is the structure of the RSA certificate at the beginning of xbox 360 container files public knowledge? I've figured out (but tell me if I'm wrong) that the rsa exponent is the 4 bytes at offset 40 (65537, very common exponent). I've also figured out that the encrypted signature is the 128 bytes at 428 (because by comparing files from my xbox, this is the only part that is different). The 384 bytes between the exponent and the signature, I have no idea about though. Public modulus? Anyways, if I could get a C structure for this that would be awesome."

will remain anonomous for now.

 

Could this be the begining of container file signing?!?

I have no idea, what you just said went right over the top of my head .

 

It does seem like you are on to something though, maybe you should try and find a partner to help you out.

i agree...anyone here ever messed with coding...or made any of the halo 2 signers...all you need to do is put that in a program and then we will be closer than ever!

So you know the setup of offset 40? So now you can create a plugin to resign that? Theres tons more offsets to go all in different types of arrays I believe.
