This program lets you write a short line and encrypt it using Caesar’s Cipher. It shows the two prior and next rotations, as well as the current encryption key.

Usage

  • Normal letters let you type text,
  • ‘Backspace’ lets you delete the last letter,
  • ‘Tab’ sets the encryption key to zero,
  • ‘Escape’ toggles if key and other rotations are shown,
  • ‘Return’ toggles if special characters (characters that are not contained in the standard alphabet) are displayed,
  • Up arrow rotates up (encryption key decreases),
  • Down arrow rotates down (encryption key increases).
