Caesar Cipher - Encrypt and decrypt messages

Learn about the benefits of cryptography by using Caesar's Cipher, one of the simplest and most widely known encryption techniques. With this application, you can encrypt and decrypt messages using Caesar's Cipher. Create a secret message, select a key, and then send the encrypted message to your friends. To decrypt it, they will need to use the same key used for encryption. Have fun!

This application allows you to easily and quickly encrypt and decrypt your messages using a simple method of substitution, in which each letter in the plaintext is replaced by a letter some fixed number of positions down the alphabet.

Caesar's Cipher is named after Julius Caesar, who used it to protect messages of military significance.
