TextEncryption

A simple Java console-based application implementing classical cryptography techniques, including Caesar Cipher and Rail-Fence Cipher.
This program demonstrates both encryption and decryption, with a user-friendly looping menu system.

Features

• Caesar Cipher

  • Encrypts and decrypts text using a shift value (1-25)
  • Handles both uppercase letters and other characters

• Rail-Fence Cipher

  • Encrypts and decrypts text using a custom key (number of rails)
  • Implements a zig-zag transposition

• Interactive Menu

  • Choose between ciphers and encryption/decryption options
  • Loops until the user chooses to exit.

🛠️ Technologies Used

• Java (JDK 17 or later)
• Object-Oriented Programming (OOP)
