The Ancast Key(s) are as useful as the Boot ROM(s). They already have been analyzed already.

If you want the big one you need the Common Key. That will allow you to decrypt system updates / games / etc. and analyze them to find exploits.

However, those are not useful by themselves as those are the public keys. You will still need to use an exploit.
You currently can't fake a system update / game without the private key.

As far as I know, you need several keys to actually make use of the Ancast key. Ancast images are both encrypted and signed, having one key doesn't cut it. It is a step forwards though, especially if you find an exploit to bypass the signature check - this would open the gates as far as heavily modified Cafe OS/vWii/NANDLoader are concerned (or so is my feeble understanding of the subject, at least).

you dont need the public/common key if the kernel is patched to run unsigned code. just ask anyone from the 360 JTAG/RGH scene

That is indeed the case, but first you need to have the kernel patched and we've already established what's needed to do that properly. :P Just because something works on the 360 doesn't by extension mean that it will work on every other system - each is unique and has its own vulnerabilities. ;)

I swear to God, if anyone references yesterday's incident one more time this thread is going straight to the bin and will be replaced with a clean one. What's done is done, what has been said has been said. Let's focus on the new and exciting discoveries made by the Wii U developers instead of dwelling on arguments that have long since ended.

Again, just to be 100% clear, the keys were removed from the thread because the "legality" of distributing them is a grey area. Reverse engineering however is legal in most countries (exceptions apply), so a method for extracting the key by yourself from your own Wii U is far more preferable and entirely legal in most territories - that's what we're more interested in.

Moving on, please guys.



Holly! dajshdkaj what happen? xD tell :3

You still need a decryption key to patch the kernel, in the 360's case it's the CPU key, which decrypts everything.
But yes, you are correct on that.

This information above / below is correct last time this post was updated.

The Ancast key(s) is used to decrypt the executable code the PPC runs. Otherwise, not very useful until you get the common key(s), because you need the common key(s) to get to the executable code.
There is also an Ancast key for the ARM processor, it is the key that will decrypt the ARM code in Wii U mode.

You're correct that on their own, the ancast keys won't let us modify ancast images (we need the signing key as well for that). However, they will help us decrypt and analyze the Cafe OS kernel once its binary is acquired.

I can't believe how people handle this, the leaked files should be removed not celebrated.

Whomever leaked it did more wrong than good with this, the guy who created the exploit is now obviously very pissed that his stuff got leaked and probably won't share his further progress with anyone anytime soon.

So nice work fucktard who leaked it, you've cost us a lot maybe even Homebrew ...

I'm pretty sure that it was "leaked" by the person who made it.
