Did You Know...

The Caesar Cipher

One of the oldest ways of sending secret codes was the Caesar Cipher. This method was developed at the time of Julius Caesar in Rome as a way to send secret messages to his generals. As an example, lay out the alphabet from 'A to Z' (look below). Next, decide how many letters to the right the coded version will be. The example below is a coded version of 2. You can see that the letter 'C' represents the letter 'A'.

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
C D E F G H I J K L M N O P Q R S T U V W X Y Z A B

Using the coded version of 2,  solve this message:

JAXG C ITGCV FCA

This was the code used in the Amazon Best Seller 'Book of Codes'.
