This is a tool I developed during my MSc to understand how a ‘Caesar Cipher’ operated.

You need the Java Runtime version 6 or above to run.
Double click on ‘CaesarCipherTool.jar’.
Enter the text you want to encode in the ‘Input’ box. Use the drop down box to select the ‘shift’, ensure ‘E’ is selected and click on ‘Engage’. The ciphered text appears in the ‘Output’ box.
Enter the text you want to decode in the ‘Input’ box. Use the drop down box to select the ‘shift’, ensure ‘D’ is selected and click on ‘Engage’. The correct deciphered text appears in the ‘Output’ box if the ‘shift’ is the same as when the text was encoded.
