About the Caesar Cipher

The Caesar Cipher, named after Julius Caesar, is one of the simplest and most well-known encryption techniques. It works by shifting the letters in a message by a fixed number of positions in the alphabet. Despite its simplicity, it provides a foundational understanding of classical encryption methods.

On this page, you can try the cipher interactively — encrypt and decrypt any text while seeing how each letter transforms!
