On the Subject of the Green Cipher
It ain't easy being green. Nor is it easy being a 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 2 pages.
On page 1, the top screen shows a 6 letter encrypted word, the middle and bottom screen shows a 6 digit number.
On page 2, the top screen shows a 3 letter configuration, the middle screen shows a number.
Follow the mechanics down below to decrypt your word:
Step 1: Homophonic Cipher
Concatenate the middle and bottom screen on page 1 to one string of numbers. Split the numbers into 6 pairs.
Next, config the table below so that the lowest value in that row is underneath the letter that is shown on the top screen of page 2. Ex: TOK means that 01 is under T, 27 is under O, and 53 is under K.
For each pair of numbers, find it in the table and use that column to get a letter.
You should now have a decrypted keyword that will be used in step 3 so hang on to it.
Step 2: Columnar Transposition
For this, you will need the encrypted word from the top screen of page 1 and the number from the middle screen of page 2.
Take numbers and underneath it, put 6 dashes so that it fits in the columns of the numbers.
