On the Subject of Notre-Dame Ciphers
And we're gonna let it burn, burn, burn, burn...
This module consists of four displays, two arrows that cycles through 4 pages of instructions, and a submit button that sends you to the submission phase.
The main goal is to scramble a 5x5 matrix using 3 particular ciphers, 3 times each, then locate where are the corresponding letters that you'll have to press.
Initializing the matrix
Get a 5x5 matrix and fill the 3rd row with the word from the 2nd display (below the "Start with :" label).
Then, fill the rest of the matrix, starting from the top-left cell and going in reading order, with the rest of the alphabet (no duplicate letters allowed). Replace Q with Z.
Rosace Cipher (Page 2)
Locate one of the chosen cells using the letter for the column and the number for the row. Then, locate the three other chosen cells using 90° rotations along the center of the matrix.
Swap these four cells depending on the third character of the key : '>' for clockwise, '<' for counter-clockwise.
Example : B1>
Because of '>', go clockwise. This means B goes to K, which goes to X, which goes to L, which goes to where B was previously in.
