crypto - as in cryptography, not cryptocurrency - is just the library he’s using to generate the 128-bit random UUID. The snippet is interesting because he matched the original UUID in just over 5 hours. You’d expect to need more than 10^38 guesses to pick the same number again, which, even at 1 guess every microsecond, means something like 10^22 years.
I wanted to downvote you for failing to pick up on the sarcasm, but then you went and did all that math that I was too lazy to do and I ended up upvoting you instead. Damn you!
