VeraCrypt hidden volumes are supposed to be a 100% deniable. There’s no way to prove they exist.

The idea is that they’ll stop torturing you because they don’t know of the existence of the hidden volume.

(In practice I suspect it leaves some subtle queues, but maybe perfect for a border crossing )

My understanding is that people who torture you don't know what you don't know; so they don't know when to stop. As such, they'll keep torturing you way past the point where you've admitted to everything you know. This is why information obtained under torture is considered unreliable: eventually you'll just say anything to stop the torture; further admissions will support the use of torture as an information extraction tactic, and then lead to more torture.

Yes but, under what pretext would you torture someone who has complied with all of your requests?

~"Do you have any encrypted data we can't see?"

"Yes. The entire drive is encrypted"

~"What is the key?"

"iloveapplesauce6969"

~"Well, that worked and I see your data here. What a lovely family.. is that Disney world?"

"Yes it was Timmy's 5th birthday"

~"I'm going to waterboard you"

Them: "You're still hiding something"

You: "This was everything!"

Them: "We don't believe you" -rubber hose-

You: "Stop it! I planned to blow up the world trade center!"

Them: "We knew you were a liar."

To themselves: "Wow, torture works."

Rinse, repeat.
