HELLO → Shift 3 → KHOOR 📌 Example Usage

Enter your message: HELLO Enter shift value: 3 Type 'e' for Encrypt

Output: KHOOR 🛠️ Technologies Used Python (Core Programming) 📈 Future Improvements Add graphical user interface (GUI) Add brute-force attack mode Add frequency analysis feature 👨‍💻 Author Abbas Ali
