This project implements a secure file-sharing system using advanced cryptographic algorithms AES, RSA, and ECC to ensure data confidentiality and integrity. Users can upload files, encrypt them with their choice of encryption technique, and securely share them with others. In case a file is attacked by a malicious user, the system ensures that the attacker cannot decrypt or access the original file due to the robust encryption. If a file is compromised, the admin has the capability to restore the file and ensure that the attacker cannot access it again. The solution integrates Django with Django REST Framework for the backend, React for the frontend, and MySQL for database management. The frontend uses TailwindCSS for responsive design and seamless user experience. The project provides a secure platform for file storage, with detailed analytics and access controls, ensuring that only authorized users can decrypt and view sensitive data. The system guarantees robust security, access management, and file protection against external threats.
