Educational Purpose Only: Caesar cipher is not secure for real encryption. It's used for learning about cryptography and creating simple puzzles.

How to use: Enter text, select encrypt or decrypt mode, adjust the shift value (1-25), and see the result in real-time. The shift value determines how many positions each letter moves in the alphabet.
