What is going on in the Caesar Cipher?
A Caesar Cipher is a very simple coding method. The original text is translated in to a coded cipher text by taking each letter in turn and replacing it by the letter a particular number of letters later in the alphabet. The number chosen is known as the “Caesar Shift”. The Caesar Cipher web page simply reverses this process, taking the coded text and replacing each letter in turn by the letter that occurs the specified number of places earlier in the alphabet. The web page uses my (Phil’s) first attempt at a spot of javascript programming. By viewing the source (select the View Source menu item in Internet Explorer) you can see this programming in all its glory.
