Secure Java Server with CA Certificate

This repository contains a simple Java project demonstrating a secure server implementation using Bouncy Castle for cryptographic operations and a Certificate Authority (CA) for secure communication.

Features

• Server implementation with secure communication.
• CA certificate generation and management.
• Key pair generation and secure storage.

Prerequisites

• Java Development Kit (JDK) installed (version 20 or higher).
• MySQL Server (xampp)

Getting Started

1. Clone the repository to your local machine:

   https://github.com/Hayan47/Information-Security.git

2. Run the server

3. Run the CA

4. Run the client

MySQL Server Configuration

To set up the MySQL server on port 3306 using XAMPP:

1. Make sure XAMPP is installed and MySQL is started.
2. Open a MySQL client, such as phpMyAdmin.
3. Copy and paste the following SQL statements into the SQL query editor.
4. Execute the SQL statements.

Create "iss1" Database

CREATE DATABASE IF NOT EXISTS iss1;
USE iss1;

Create user Table

CREATE TABLE IF NOT EXISTS user (
    name VARCHAR(20),
    password TEXT(50),
    number INT,
    role ENUM('student', 'doctor')
);

Create message Table

CREATE TABLE IF NOT EXISTS message (
    name VARCHAR(20),
    message TEXT(100)
);

Create marks Table

CREATE TABLE IF NOT EXISTS marks (
    student_name VARCHAR(20),
    marks TEXT(100),
    id INT AUTO_INCREMENT PRIMARY KEY,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

Usage

• Update the keystore password in the code to match your security requirements.
• Modify the CA's subject distinguished name and other parameters in CertificateGenerator based on your use case.
• Customize the server logic in the Server class as needed for your application.
