Am I misremembering, or was there some cryptographic system where you could set up a container and have two keys to it, each of which provided a different file with no way for anyone to prove the other file/key existed?ie, if the authorities forced you to decode it, you could give them the fake key and they'd only get the fake contents, and they couldn't prove that you have another key which reveals other contents?

@foone truecrypt had secret volumes like that iirc

@foone this is real, I remember it too. Have no idea how to find it.

@foone I think Truecrypt had a similar "hidden volume" feature.

@foone TrueCrypt maybe? It had hidden file systems with plausible deniability (with some questions about how foolproof that was against analysts). It was discontinued a long time ago though…

I was just wondering because I was thinking about the plausibility of shipping a video game with this technology, so that you could use deniable encryption to hide video game content.

Even the NSA can't prove that there is or isn't a cow level

@foone but you still need to give some people the key, right

@whitequark I was figuring that you'd be able to do things in the game to generate the key. Like if you do one quest, a specific bit is 1 but 0 otherwise. So only by getting the game into the exact right state can you employ the second key

@foone oh, that's wildthat said... if you can see it often enough through casual play you can definitely brute-force it easily(this presumes that there is a checksum that tells you whether the secret level is decoded correctly or not. if there isn't it's equivalent to generative art, i think)

@foone @whitequark I built a few crackmes that worked like this. similar idea to measured execution, except simpler and with much looser threat models.

@foone @whitequark If you know what you're doing then you can even do this with "normal" modes of encryption like AES-GCM. That super common mode isn't key- or message-committing, so you could create a single ciphertext which decrypts differently for different keys. Even less suspicious.

@foone In a game the size of the container would be suspicious. Why would your game include a 5 MB container you only extract 2 MB from?

@foone a few years ago I made a game that shipped on a very limited number of USB sticks. If you played it with the USB plugged in, it would play the actual game, if you copied the folder off and removed the USB it launched into a different B-side version of the game. I think adding encryption to something like that would genuinely be really cool
