Cipher Encryption Project

A simple Java-based encryption system that demonstrates classic cipher algorithms and basic GUI handling.
This project was made for Data Structures and Algorithms.

---

Features

• Implements multiple cipher algorithms:
  • Vigenère Cipher
  • Bifid Cipher
  • Polybius Cipher
  • CipherX (custom cipher implementation)
• Central interface through Home.java
• Uses visual icons for an interactive interface
• Demonstrates string manipulation and GUI programming concepts

---

Requirements

• Java JDK 8 or higher
• Eclipse IDE with WindowBuilder plugin (required to run or modify the GUI)

---

How to Run

1. Install Java JDK 8+ and ensure it is added to your system PATH.
2. Open the project in Eclipse IDE.
3. Make sure the WindowBuilder plugin is installed.
   • In Eclipse, go to: Help > Eclipse Marketplace > Search "WindowBuilder" > Install
4. Compile and run the program:
   • Right-click on Home.java → Run As → Java Application
5. The main interface will appear and allow you to test different cipher algorithms.
