🚀 How to Run

1. Make sure you have Python 3 installed.
2. Clone this repository or download the main.py file.
3. Run the script:

python main.py

🧠 How It Works

The Caesar Cipher shifts each letter in the message by a specified number of positions through the alphabet.

For example, with a shift of 3:

A → D

X → A

z → c

It wraps around the alphabet and ignores non-alphabet characters (like numbers, punctuation, and spaces).

⚙️ Requirements

• Python 3.x

• No external libraries required

• Uses built-in tkinter, messagebox, and filedialog

📌 Notes

Make sure to enter a valid shift value between 0 and 25

You can load text from files and save results as .txt
