Cloud Based Storage Encryption Decryption in Python Projects

Cloud Based Storage Encryption Decryption in Python Projects
Abstract
With the growing use of cloud services like Google Drive, AWS S3, and Azure Storage, data security and privacy have become major concerns. Sensitive data stored in the cloud is vulnerable to cyber-attacks, unauthorized access, and data breaches. This project introduces a secure cloud-based storage encryption and decryption system using Python. The system uses cryptographic algorithms such as AES (Advanced Encryption Standard), RSA (Rivest–Shamir–Adleman), and Fernet symmetric encryption to protect data before it is uploaded to the cloud. Users can encrypt any file locally and store the encrypted version securely on the cloud; the file can only be decrypted using a valid secret key. This system ensures confidentiality, integrity, and secure transmission of data, making it suitable for academic, business, and personal secure storage applications.

Existing System
The traditional method of cloud file storage uploads files directly to the cloud without encryption. This leaves data vulnerable in case of cloud provider hacking, insider threats, and unauthorized access. Many cloud platforms use server-side encryption, but this means cloud providers still control the decryption keys, posing privacy risks. Existing systems also lack customizable key management and local offline encryption options, leaving data security largely dependent on third-party controls.

Proposed System

The proposed system provides client-side encryption, meaning the data is encrypted locally using a unique key before being uploaded to the cloud. Even if the cloud server is compromised, attackers cannot read the contents without the decryption key. The project uses Python cryptography libraries to implement encryption and decryption. The system also allows password-based key generation, secure key storage, and integration with cloud services like AWS S3 or Google Drive using APIs. A user-friendly interface is developed using Flask or Tkinter for easy file upload, encryption, and download.
