Secure File Sharing System

A full-stack secure file-sharing web application built using Django (backend) and Angular (frontend). The system focuses on secure data transmission, encryption, and controlled file access between users.

⸻

🚀 Project Overview

This project demonstrates a secure file-sharing system designed to simulate real-world secure data exchange between users. It implements authentication, role-based access control, and encryption mechanisms to ensure safe file storage and transfer.

The system follows a full-stack architecture with a RESTful API backend and a responsive frontend interface.

🧰 Tech Stack

Frontend:

• Angular
• HTML, CSS, TypeScript

Backend:

• Django
• Django REST Framework

Database:

• SQLite3

Security:

• AES-256-GCM Encryption
• RSA Encryption for key exchange

Tools:

• Git
• Postman
• VS Code / IntelliJ IDEA

Security Design

• Files are encrypted before storage using AES-256-GCM
• RSA encryption is used for secure key exchange between users
• Authentication system ensures only authorized users can access files
• Access control rules prevent unauthorized file retrieval

⚠️ System Limitation

This project previously used AWS S3 for cloud file storage. Due to expired AWS credentials, cloud storage integration is currently inactive. However, the core system—including authentication, encryption, file processing, and access control—remains fully functional and demonstrates the intended security architecture.

How to Run the Projec

• Backend (Django)

• Frontend (Angular)
