Make it only decrypted by brute force, taking into account the history of the algorithms and the computational level. There is no clue, you just have to use the knowledge of the time to try to solve it. You can even create the program and its minimum requirements to make sure they have a direction.
- shawnz 2y agoThat would only let you plan the average time it takes the secrets to be decrypted, it could actually take anywhere from 0 to 2*t to actually decrypt them by brute force
- 0cf8612b2e1e 2y agoAvailability of computational power is unknowable. You have encouraged all governments to create a Manhattan Project to brute force future space magic. There would be nearly unlimited funding to cryptographers and hardware design processes.
- geor9e 2y agoHow does that ensure it only gets decrypted after a certain date? Brute force can decrypt it on the first try, or the trillionth try, with equal chance.
- patmcc 2y agoIt's statically ensured, the same way I can trust if you generate a Bitcoin address right now it won't have a few thousand bitcoins in it.
- shawnz 2y agoNo, it's not like that: generate a random Bitcoin address and it's practically guaranteed that it will be empty. But in this case, if the time traveler picks a random key for their secret, it's equally likely that it gets brute forced on the first attempt as it is the trillionth attempt. There's no statistical guarantee except that on average it will take a certain number of attempts.

- geor9e 2y agoStatistically? With that analogy, you'd design a crypto algorithm that, on average, gets cracked on the desired date to guess the wallet with a few thousand bitcoins. You still have the problem that (1) guessing it right on that desired date, (2) guessing it right today, and (3) guessing it right on a day 42 times the amount of time as the desired date, all have exactly equal probability. You don't get to pick from infinite timelines to make your plot work, you get 1 try, and need to be somewhat sure it'll work on that date. It might not be possible. Unless you time travel and just hand them the information.
- Workaccount2 2y agoSure but the compute difference between decades isn't as dramatic as decrypting vs not decrypting Bitcoin.
- kdkdodiei4 2y agoWell, I don't know, I just give a seed. Basically they are using a unicorn called a "space traveler", I don't know anything about it. But if you come from the future, you know everything xD.
- piloto_ciego 2y agoThis doesn’t help because you have a time machine. You automate the activation of your Time Machine and have the Time Machine go back in time 40min and try to crack it, if it’s not cracked it goes back another 40minuted and tries again until it cracks the code. The code might take 80 years of time in the time loop but for you it’s instantaneous.
