Project Overview

This project demonstrates the classic Caesar cipher encryption technique, allowing users to shift letters within the alphabet to encode and decode messages. Initially built as a Python command-line application, the project was later enhanced with a web-based interface using Streamlit.

Core Functionality

Text Encryption and Decryption

Users can encrypt or decrypt messages by selecting a shift value and processing alphabetic characters accordingly.

Dynamic Shift Handling

Modulo operations ensure smooth wrapping around the alphabet, preventing index-out-of-range errors during character shifts.

Input Flexibility

Only letters are modified while numbers, spaces, and special characters are preserved as-is, offering a seamless user experience.

Technologies Used

Python for building the encryption logic and Streamlit for creating an interactive, real-time web application frontend.

Highlights

• Streamlined encryption and decryption process
• Robust input handling and error prevention
• Interactive user interface with instant feedback
• Shift value selection and real-time result display
