On the Subject of the Inverted Cream Cipher
Only those that are the cream of the crop can solve this cipher.
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 4 pages.
On page 1, the top screen shows a 6 letter encrypted word, the middle and bottom screen displays a digit string.
On page 2, the top, middle, and bottom screen shows a 6 letter word. Same thing with page 3.
On page 4, the top and middle screen shows an encrypted string, the bottom screen displays a 7 digit number.
Follow the mechanics down below to decrypt your word:
Step 1: Grandpré Cipher
Take the keywords from the top, middle, and bottom screens from page 2, then page 3 in that order and write them below each other, forming a 6×6 matrix. Write numbers 1 - 6 along the top and left side of this matrix.
The numbers on the middle and bottom screen of page 1 are an encrypted keyword. Treating each number in the middle screen as the row and each digit in the bottom screen as the column, use the intersection of each number pair in the matrix to get a decrypted keyword. This will be called Keyword A.
Middle Screen: 3165
Bottom Screen: 1256
