Hacking Hackin Wii encryption

[KaiWren]

OK, i'm a bit new to the scene, so forgive me if this has been asked and answered.
From my understanding, you can't take a channel, be it VC, or the HBC, and transfer from one wii to another, due to the private encryption algorithm, right?
Has anyone tried to break this encryption? do we know what algorithm they're using? if we can crack WPA encryption in 7 minutes, why can't we do the same for the wii? i've got tons of computing power to throw at this, if some genius coder can write a distributed computing tool. seems like we'd need a large sample from Xyzzy, to look for similarities in the encryption. anyway, i'm just spitballing here, waiting to be able to install HBC on my 4.0u wii...

Nope, no HBC for me, updated to 4.0 before i heard about homebrew of any sort.

you're screwed for now then

right, i get that, i was trying to see if it would be possible to extract the keys from a channel on a virgin 4.0 wii, and then place those keys in a different channel, such as the HBC.

i know we can't, currently. but there has to be something stored in the channel to identify it to the unique nand key, right? if we got a large enough comparison group, coupled with a large enough distributed computing effort, we should be able to crack it the same way people crack RSA 128 bit encryption, in theory. i was just wondering if this has been attempted, and if not, let's get something going.

i'm sure they don't either, but they've got to store a hash of some sort, that's how keys work. if we could compare hash to keys, and find enough of a similarity, we should be able to come up with the key by using the hash.

And then look up exponentials.

Who can crack RSA 128-bit (excluding the NSA)? To my knowledge the largest RSA key that was cracked with a distributed effort was 64 bits and it took about 3 years.

The ticket for any downloaded channel includes your wii's unique ID and the ticket is signed using nintendo's private key. The idea of private/public key encryption is that you can't (feasibly) figure out the private key using the encoded message and the public key.
