Encryption Tools

Overview

This repository contains various encryption tools starting with the Caesar Cipher. These tools are designed to help understand and apply fundamental cryptography techniques. The project will grow to include more encryption algorithms in the future.

Tools

1. Caesar Cipher

The Caesar Cipher is a simple substitution cipher where each letter in the plaintext is shifted by a certain number of positions in the alphabet.

How It Works:

• Encryption: The user inputs a text, and each letter is shifted right by the specified number of positions.
• Decryption: The user can shift the encrypted text left by the same number of positions to restore the original message.

Features:

• Supports both encryption and decryption.
• Input validation ensures that only alphabetic characters are processed.

Encryption Example:

• Original text: hello
• Shift: 3
• Encrypted text: khoor

Decryption Example:

• Encrypted text: khoor
• Shift: 3
• Decrypted text: hello

Installation

1. Clone the repository:

   git clone https://github.com/ADIR360/Encryption-Tools.git
   cd Encryption-Tools

2. Run the Caesar Cipher scripts:

   • For encryption:

     python caesar_cipher_encrypt.py

   • For decryption:

     python caesar_cipher_decrypt.py
