☁️ Vault Cloud: Secure File Sharing Service

1. Project Goal & Problem Statement

This project developed a robust, secure, and easy-to-use cloud-based file sharing and storage platform. The core goal was to implement strong security measures to protect shared data, moving beyond typical link-based sharing by enforcing encryption and access controls.

2. Solution and Key Security Features

Vault Cloud is a full-stack solution focusing on data security and controlled access:

• AWS S3 Integration: Files are stored securely using AWS Simple Storage Service (S3), leveraging its industry-leading scalability and durability for data persistence.
• Password-Protected Sharing: Implemented file-specific, one-time passwords for accessing shared files. Users must enter the correct password before the file download link is generated.
• Secure Data Encryption: Utilized JavaScript and Node.js to ensure secure data handling, including encryption-at-rest for sensitive files.
• Modular Backend API: Developed an API using Node.js to manage file uploads, link generation, and password validation processes.

3. Technology Stack

• Cloud Service: AWS S3
• Backend Runtime: Node.js
• Programming Language: JavaScript
• Dependencies: (List key NPM packages here, e.g., express, aws-sdk)

4. Setup and Deployment

1. AWS Configuration: Requires setting up an AWS S3 bucket and configuring the appropriate IAM credentials for the Node.js application to access the bucket.
