alt Hacker NewsWrite an array of random values to a hard drive — terabytes of them.
Dupe the drive.
You now have a matching pair of "one-time pads" for, I have heard, the hardest form of encryption to decrypt. I would think expect there is a business already doing this.

It's harder to ensure that no one messed with the drives during transport than to give a small private key to the other party.

There aren't a ton of use cases for this that aren't met better by other cryptographic solutions.
Used properly, encryption using one time pads produces data streams that are indistinguishable from uniformly distributed random noise and cannot be cracked (https://en.wikipedia.org/wiki/One-time_pad)
