On the Subject of Atbash Cipher

R nvnliravw Zgyzhs! - cerulean

A 15-letter message will appear on a display screen which has been enciphered using Atbash. Decode it and input your answer using the randomized keyboard.

The big display can be pressed at any time before the 15th letter is inputted to clear your input.

The module will automatically submit when 15 letters have been inputted into the module.

If the string is correct, the module will be solved. Otherwise, it will cause a strike and reset the module.

NOTE: The keyboard will randomize each time you press a button (including the screen).
