I don't think you can resign files that big I'm not sure just guessing.

They are signed by MS.

Also if this has anything to do with a JTAG, FreeBOOT disables the LIVE/PIRS signature check.

LIVE/PIRS require a *key* provided by Microsoft which only they have access to for example if a dev wants it signed they send it to MS.

Without the *key* resigning is impossible and a brute force would take literally forever.

In the case of CON files the *key* is stored in the keyvault since they are created and signed locally by the console.

Is forever a few weeks or literally forever (years).

Someone should take up a job at microsoft and leak the key :wink:

I'm pretty sure only one person at MS has access to the key. And it would take years. Since there's 2 ^ 2048 different algorithms it could be

Someone worked it out once and it would take like a few thousand years to bruteforce if pc's were 100 times faster.

No one has worked it out...

The Live files are signed with a RSA key if im not mistaken

The RSA Key has two parts. A public Key and a private key. To get either one of these you need the other one and as we don't have either one we cannot get the other one
