With the exponential surge in digital data generation, ensuring secure and efficient file sharing has become a critical concern, especially in environments constrained by limited local storage and heightened risks of unauthorized access. This research introduces a cloud-integrated file-sharing system fortified by a hybrid encryption framework that combines the symmetric strength of the Advanced Encryption Standard (AES) with the asymmetric key distribution capabilities of the RSA algorithm. The system ensures that files are encrypted before being uploaded to Amazon Web Services Simple Storage Service (AWS S3), where they remain protected during both storage and transmission. To maintain strict data access policies, the platform incorporates role-based access control and a secure authentication mechanism, thereby preventing unauthorized data usage while enabling seamless access for legitimate users. This layered security approach not only mitigates data breach risks but also optimizes storage utilization by minimizing the need for local data retention. The proposed architecture presents a scalable and reliable solution tailored to the evolving demands of secure file exchange in distributed computing environments.
