The Twelve Days of Christmas 2025 Challenge - Double Time

[cyclone]

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...

Mrs. Claus is asking if anyone has seen her scarf... or was it her shawl?

Congrats to everyone who has completed Challenges 01 - 06! Things will start getting harder soon as the Challenges progress, so enjoy the next few "easy" ones.

Also, if you are the winner of a Challenge, as a gentlemen's agreement, consider giving everyone else a 5-10 minute head start for the next few Challenges so others can have a chance at 1st place. UPDATE: https://forum.hashpwn.net/post/7931
Winning 1st on the Daily Challenges won't help your chance at the Grand Prize, but paying attention to the Challenge Hashes and Hints will.

Another elf, another weird encoding. 3 2, 1, let's go figure it out!

PRO TIP from Santa's helper:
Are you making a Word of the Day list, and checking it twice?

[cyclone]

We had another sponsor join in on the fun and donate towards the Grand Prize. That brings the prize pot up to 0.158879 ETH... which is currently $464 USD!

It's not too late to join the fun and have a chance at winning the Grand Prize! Just make sure to go back and start from Challenge 01.

Dear Santa Claus, why so many dits and dahs? Does hashgen support this mode?

PRO TIP from Santa's helper:
Oh my, you are not going to like the challenges ahead for two reasons:
11. Not everyone parses hashes the same, so prepare to be annoyed.
12. Things will be very difficult if you haven't found the source.

[cyclone]

Merry Christmas Eve!

The easy part of the Challenge is coming to an end, and everyone should find the upcoming Challenges a bit more complex to solve. Don't let that discourage you from continuing though as there's still more prizes to be won.

With that said, let's consider the "gentlemen's agreement" over, and all bets are off on who finishes Challenges 11 and 12!

Blitzen introduced me to this bloke 2day at our Christmas party. He's supposed to be the fastest hash around, but the word around Santa's Workshop is that hashcat doesn't like this hash's format as-is, and the submitter doesn't like hashcat's format! What a joke! Why can't everyone just place nice?!
Make sure to submit hashes back in their original format and order!

PRO TIP from Santa's helper:
You'll be completing the 12th challenge soon and unlocking the latest hashpwn wordlist, but somewhere, hidden in plain sight within these 12 challenges, will be a 13th puzzle which is the Grand Prize. Good luck finding it!
