Challenge 01 - HINT
UTC: 2025-12-20T04:49:00ZSanta suggests you use your favorite wordlist on this coMMon algo.
PRO TIP from Santa's helper:
- When submitting, you must keep the original order and format of hashes exactly as they are posted on the challenge.
- The first letter of each plaintext will then spell out the Word of the Day... write that down!
- To keep you from unnecessarily banging your head against the wall on a few challenges, the submitter is not case-sensitive.
- Take good notes!
-
Given it's been solved, I'm probably just being silly here but what is the word of the day and/or how do we find it? (if it's not a part of the challenge?)

Way to go everyone!
So far the puzzles have been easy, but don't get too comfortable. Things will get harder, and they seem to be building toward something big! Stay sharp and pay attention...
