Caesar Cipher Online - Encrypt and Decrypt
BackHow the Caesar Cipher Works
The Caesar Cipher is a substitution technique where each letter in the text is replaced by another letter that is a fixed number of positions down the alphabet. For example, with a shift of 3, 'A' becomes 'D', 'B' becomes 'E', and so on. It is named after Julius Caesar, who used this technique to communicate with his generals.
