Features

• AES Encryption: Files are encrypted using AES-256, ensuring that only authorized users can access the data.
• JWT Authentication: Users must authenticate with a JWT token before storing or accessing files.
• Virus Scanning: Each file is checked for viruses to enhance security.
• User-Friendly Interface: Designed with usability in mind for seamless file sharing.
• Cross-Platform Support: Works on various operating systems, making it accessible to everyone.

Technologies Used

• AES: Advanced Encryption Standard for secure file encryption.
• JWT: JSON Web Tokens for user authentication.
• Node.js: Server-side platform for building the application.
• Express: Web framework for Node.js to create the API.
• MongoDB: NoSQL database for storing user data and file metadata.
• Multer: Middleware for handling file uploads.
• ClamAV: Antivirus engine for scanning files.

Installation

To get started with Secure File Sharing, follow these steps:

1. Clone the repository:

   git clone https://github.com/jacobPRO123/secure_file_sharing.git

2. Navigate to the project directory:

   cd secure_file_sharing

3. Install dependencies:

   npm install

4. Set up environment variables: Create a .env file in the root directory and add the following variables:

   PORT=3000
   JWT_SECRET=your_jwt_secret
   MONGODB_URI=your_mongodb_uri
   

5. Start the application:

   npm start

Usage

Once the application is running, you can interact with it via the API or the front-end interface.

API Endpoints

• POST /api/auth/login: Authenticate a user and receive a JWT token.
• POST /api/files/upload: Upload a file after authentication.
• GET /api/files/:id: Download a file using its ID.

For more detailed usage, refer to the API Documentation.

How It Works

File Upload Process

1. User Authentication: Users log in using their credentials. If successful, they receive a JWT token.
2. File Upload: The user uploads a file, which is then encrypted using AES-256.
3. Virus Scanning: The file is scanned for viruses using ClamAV.
4. Storage: If the file passes the virus scan, it is stored in MongoDB with its metadata.

File Download Process

1. User Authentication: The user must provide a valid JWT token to access files.
2. File Retrieval: The application retrieves the encrypted file from the database.
3. Decryption: The file is decrypted using AES-256 before being sent to the user.
