If it helps, write down your plain text message first then encode it one letter at a time (such as the “hello” example above).

Write down your encoded message using your shifted alphabet.It might be easiest to start out with a simple message (such as a single word or phrase) before you try longer sentences or paragraphs. Pick a message to write to your friend.Shift the entire alphabet by the number you picked and write it down below your original alphabet (as shown above).(If you use 26, you will just wind up with the original alphabet.) This number is your key. Explain the concept of a Caesar cipher to a friend or have them read the background section of this activity.After that you can send messages that are written in cipher so other people can't read them! In order to decode your message, you need to share the “key” (the number 3) with your friend. So, when you write your message, the letter A gets replaced with X, B gets replaced with Y and so on. For example, this would be your key and code if you shift each letter by three spaces: It is a simple form of a “substitution cipher” where you replace each letter of the alphabet with another letter by shifting the whole alphabet a certain number of letters (wrapping around to the beginning once you reach the end). The Caesar cipher, named after Roman Emperor Julius Caesar is one of the earliest and most widely known ciphers. Now cryptography is essential in computer science for keeping everything from e-mails to bank account information secure. Many of the earliest codes, or “ciphers,” such as the one you will create in this project were easy to create by hand.

Historically, codes have been used by politicians, spies and countries at war to prevent their enemies from knowing what they’re up to.
