ROM Hack Do we have the technology to fully decrypt games on PC yet?

[Deleted User]

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.

3DS only using Decrypt9.

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.

ok, thanks anyways

Can't you decrypt games with CTRTool?

No, you can unpack games though.

Huh. Never really thought about that. You learn something new every day.

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?

I understand.

yes, if. but we don't right now.

 

[Aletron9000]

yes, if. but we don't right now.

but didn't someone leak dev keys containing retail and dev common keys?

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 know, but there is a file floating out there that has, what i think has dev AND retail common keys. for developer units and retail units.

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

there are a lot of pastes on pastebin. what are you talking about?

if you search on google "pastebin 3ds common key" you will see it, can't put a direct link
