If it's so easy to guess a uuid, here you go

I ran crypto.randomUUID() twice on my machine.

The first ID was 15041508-fd38-4eda-bc1d-7b74e4738cd9

The second? That's your challenge.

I encrypted a text file with the following command:

openssl enc -aes-256-cbc -salt \
  -in impossible-challenge.txt \
  -out impossible-challenge.txt.enc \
  -pass pass:{2nd-uuid-goes-here}

If you can crack this UUID, I'll give you $1,000.

Tbh it will probably easier to brute force the decryption than to guess the right ID.

My very smart friend solved this challenge and called me over to show me the solution. But when I got there, the police was all over, and I heard he was shot dead. Apparently he hacked into NSA or something.

The bastard had a failsafe that wiped his computers clean with the DoD 5220.22-M algorithm. Now there's no chance of getting that solution.

wow, such a shame...
