    Like the title says. I know I have asked this question before, but do we? I can't find that thread to bump it for the life of me.

    actually north korea. please send help
    I'm pretty sure we don't yet, for that we'd need bootrom access from what I've heard, 'cause then we'd have access to all the 3DS' keys.

    Fair enough. But that being said, since Dec9 can decrypt games, is there a specific way it reads the keys from the bootrom?

    It doesn't read them from the bootrom, it just has access to them since it's running on the console, I think? I'm not too great at explaining this, so it'd be better to ask someone else who knows more about it.

    Can't you decrypt games with CTRTool?

    the bootrom needs to be dumped to get the secret encryption keys. once that happens you can de/encrypt games offline (i.e. without 3DS)

    isn't it possible to encrypt ncch on the computer if you have the common key?

    developer keys are not the same as retail keys. we don't have a few keys, namely original NCCH Key X (0x2C), "Common Key X" to de/encrypt title keys (0x3D), as well as several others.

    I doubt it actually has the proper retail keys.... if it did, we'd probably already be de/encrypting titlekeys or something on our PCs.

    check pastebin, i found it there

    pretty sure common keys cannot decrypt/encrypt title keys, that still needs key scrambler
