RSA Algorithm Demo

Overview

This project is a simple web-based demonstration of the RSA algorithm, a public-key cryptography system used for secure data transmission. The application allows users to input two prime numbers (P and Q) and a numeric message, then performs RSA encryption and decryption to showcase the algorithm's functionality. https://rsa-algorithm-compression.netlify.app/

Features

• Input Fields: Enter two prime numbers (P and Q) and a numeric message.
• RSA Process: Computes the public and private keys, encrypts the message, and decrypts it.
• Educational Content: Provides an overview of the RSA algorithm, its advantages, and disadvantages.
• Interactive UI: Simple HTML-based interface for ease of use.

How It Works

1. Input Prime Numbers: Users provide two prime numbers, P and Q, which are used to generate the public and private keys.
2. Input Message: A numeric message is entered for encryption.
3. Run RSA: Clicking the "Run RSA" button triggers the RSA algorithm to:
   • Calculate the modulus (N = P × Q) and totient (φ(N) = (P-1) × (Q-1)).
   • Generate the public key (e) and private key (d).
   • Encrypt the message using the public key.
   • Decrypt the message using the private key.
4. Output: Displays the encrypted and decrypted messages.

Prerequisites

• A modern web browser (e.g., Chrome, Firefox, Edge).
• Basic understanding of RSA cryptography (optional, but helpful for context).

Installation

1. Clone the repository:

   git clone https://github.com/Vijitverm1234/RSA-Algorithm.git

2. Open index.html in a web browser to run the application locally.

Usage

1. Open index.html in a browser.
2. Enter two prime numbers (P and Q) in the provided input fields.
3. Enter a numeric message to encrypt.
4. Click the "Run RSA" button to see the encryption and decryption results.

File Structure

• index.html: The main HTML file containing the UI and RSA logic.

Limitations

• The demo is designed for educational purposes and uses small prime numbers for simplicity.
• The message must be a numeric value to work with the RSA algorithm in this implementation.
• The application does not handle non-prime inputs or invalid messages gracefully (consider adding validation for production use).

Future Improvements

• Add input validation to ensure P and Q are prime numbers.
• Support text-based messages by converting them to numeric values.
• Include a visual step-by-step breakdown of the RSA process.
• Enhance the UI with CSS styling and responsive design.
