Why Choose This Project

In the modern digital world, sharing files over the internet exposes sensitive data to risks like interception, unauthorized access, or tampering. Traditional file sharing methods often lack proper encryption or access control. This project creates a secure platform where files are encrypted before upload and can only be decrypted by authorized recipients, ensuring confidentiality, integrity, and controlled access.

What You Get

A web-based platform where users can upload files, encrypt them using strong cryptography (AES/RSA), and share with specific recipients. Users can set expiration times, download limits, and access permissions. The platform maintains secure storage and provides detailed logs, making it ideal for enterprises, legal offices, healthcare, or any scenario requiring secure file sharing.

Working Flow

1. User Login: Users log in securely using credentials or 2FA.

2. File Upload & Encryption: Files are encrypted locally or server-side before storage.

3. Set Permissions: Users assign recipients, download limits, and expiry times.

4. Storage: Encrypted files are stored securely in the database or cloud storage.

5. File Sharing: Share download links or email notifications with authorized recipients.

6. Access & Download: System verifies user identity, access permissions, and expiry before decrypting the file for download.

7. Audit Logging: All uploads, downloads, and access attempts are logged.

8. Dashboard Visualization: Admins or users can view file sharing trends, downloads, and access logs.
