Common keys are just one part of the encryption here. If you want to install modified software directly to sysnand, you need the private keys. (the keys used to "sign" the files so that bootrom will accept them)

Something only Nintendo has at a secret location. Even developers don't get these keys. They get dev keys so they can test things on special dev units. But for retail units, only Nintendo has them.

For the private keys to get leaked would take a major hacking incident or a insider that directly works with them to leak them. I don't see this likely to occur anytime soon. To be honest you have better luck finding a bootrom exploit then getting your hands on the private keys. :P

Would love to see this happen.
Makes launching homebrew a little easier.

It's very debatable whether a [more or less pseudo-]randomly generated number is sufficiently original to be copyrightable (same reason many logos aren't copyrighted, only trademarked)!

No, it sounds very silly. On the other hand, video games, say, are nothing but very long groups of numbers, so it has to be protected somehow.

Now that I think about it the common keys are probably used to generate the title keys. So if you had the common key you can generate a title key for any title you want on the 3DS even for games you don't own, then download the title from CDN and decrypt it (or generate a CIA of it that could work on unmodified sysnand once you import the title key you used into the ticket/title.db files in the dbs folder)

You still need an exploitable console to generate a title key/install the resulting CIA however. Sorry SKy3DS users. Still no eShop games for you. :P

EDIT: Long story short, this only allows you to download and use official Nintendo content. You can't use the common keys to install modified software as you need to sign them and that is the part that requires the private key. ;)

But they're blatantly generated as a computer transformation of creative effort, unlike a number...

Why would someone ban a number long about 750*1024*1024*8 binary digits long just because you can coincidentally obtain it with `dd if=/dev/hdc of=office2000.iso`?
