Text Encryption/Decryption and RSA Key Generation App

This is a simple web application that allows users to input text, submit it, and see the encrypted/decrypted value using the AES-256-CBC algorithm. Additionally, it provides functionality to generate RSA key pairs (public and private keys).

Features

• Encrypt/Decrypt text using AES-256-CBC.
• Display the encrypted/decrypted text on the web page.
• Generate RSA key pairs (public and private keys).
• Display the generated RSA keys on the web page.
• Responsive design with basic styling.

Prerequisites

• Node.js
• npm (Node Package Manager)

Installation

1. Clone the repository:

   git clone https://github.com/Esom/gmc-final-project.git
