This might take some patience if a human does it, but nowadays computers can unravel the code in a fraction of a second, so Caesar ciphers are not considered a secure method to encrypt electronic communications.

Extra: Try finding a third person who does not know what a Caesar cipher is.Try switching and using a different key for the same messages.Using the example from the background, the letter x becomes a y becomes b and so on. If it helps for the first try, let them work backward using the original and shifted alphabets you wrote down. See if your friend can decrypt your message.Why do you think you wouldn't want to write down the key? Give your friend the encoded message and tell them the key.Just make sure the piece of paper you give your friend only has the encoded message! 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.

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.

Try this activity to learn how to create your own “Caesar cipher,” a popular type of code that is easy to learn.Ĭryptography is the study of writing or solving secret codes that are used for secure communication. If you need to send a secret message to a friend, how could you prevent other people from reading it? One way is to encrypt the message-that is, use a secret code that only you and your friend know.
