Hacking About 3ds encryption

WARNING
Programmer talk. If you do not know what is a programming language, go read something else.

I got a free time and i would like to study a little about 3ds encryption. So I wanted to know where I can get information about the topic. Right now, what we know about how is the encryption process of the software running on the 3ds? and when the 3DS will run the code, how the decryption is done?

All info we have is on that site...

thanks for the reply, I looked quickly the website and there is no much information on it... you don't know another site?

It's 3dbrew.org, not .com. And there's plenty of info there. As much as you'll find anywhere right now.

Really? Neimod, yellows8 and few other notables have been posting info on that site constantly for the last 2 years.

But okay then, since you asked, here is the next best thing:

at the time, the big problem is the 3ds encryption. For example, IF there is an information that it is based on certificates or keys, to me would be a starting point to guide my studies.

If you need specific info you can get on 3dbrew's IRC. Its on efnet - 3dsdev.

Make sure to ask good questions or they will ignore you though.

Thanks for the tip. I'll try.

(Note that the ARM11 kernel does not handle any encryption/RSA verification, this is handled by the ARM9)

etc.

reading this page, i suppose that the following happens:
- The cartridge transfers the command to the console
- The console decrypts the command
- The console runs the command.

On that page it assumes that the encryption used is AES CTR.

It would be correct to say that the encryption is based on certificates then?

The Wii and DSi use titles/tickets in the same manner (as some pages mention) for downloadable content, but no clue on carts.
