On the Subject of The Inverted Blue Cipher
Blue is often to describe sadness. Luckily for you, this cipher will cheer you up.
On the module, you will see 3 screens, a keyboard, 2 arrows, and a submit button that displays the current page you're on.
Pressing the right arrow takes you to the next page. Pressing the left arrow takes you to the previous page. There is a total of 2 pages.
On page 1, the top screen shows a 6 letter encrypted word, the middle and bottom screen shows an 6 digit number.
On page 2, the top screen shows a word.
Follow the mechanics down below to decrypt your word:
Step 1: Tridigital Cipher
First thing you need to do is create a key. To do so, take the keyword from the top screen of page 2 and remove any duplicate letters.Take the entire alphabet and remove any letters that is shown in the keyword.
If the number of indicators is even, place the alphabet at the end of the keyword. Otherwise, place the alphabet at the beginning of the keyword.
Then arrange the key you made by splitting the key into 3 rows. The 1st and 2nd rows should have 9 letters and the 3rd row should have 8 letters.
The numbers on the middle and bottom screen of page 1 is an encrypted word using the key you made.
Treat the middle screen as the rows of each number and the bottom screen as the columns of each number.
For each row/col pair, use the intersection in the key to get an decrypted letter.
You should now have a decrypted keyword that will be used in step 3 so hang on to it.
