Would that be akin to me offering a hash string as a puzzle and asking for the 10GB video file as the solution?

- kop316 1y agoSort of. A one time pad does not destroy data, but a hash will. Wikipedia has a good example: https://en.wikipedia.org/wiki/One-time_pad https://en.wikipedia.org/wiki/One-time_pad In their example, "HELLO" is the plain text, "XMCKL" is the key, and the ciphertext is "EQNVZ". However, with a one time pad, an equally plausible plain text is "later" with the key "TQURI". Thus, without anymore data, it is simply impossible to know what the original message is.
- lazide 1y agoWas the 10GB video file never released anywhere and is stored in a now bit rotted old HD in your basement? Reasonable puzzles can be worked out (albeit maybe with a lot of work) with information provided by the puzzle or available somewhere in the environment. Unreasonable puzzles (like some old Sierra games cough) are impossible without secret inside knowledge by the puzzle maker and/or brute force. And sometimes not even with brute force. The hash/video example might just be an Easter egg hunt requiring looking across a wide set of videos (somewhat reasonable but boring), or completely unreasonable depending on circumstances.
