Nimbus Cloud Storage

Overview

Nimbus is a high school project I worked on to explore cloud storage and encryption concepts. This project is not intended for actual use, as it may contain bugs and security vulnerabilities.

Nimbus is a client-server cloud storage system that allows users to upload, download, and manage files and folders efficiently. It features AES encryption for file security, RSA encryption for key exchange, a Tkinter-based GUI, and an admin panel for user management and monitoring.

Features

• User Management

  • Sign-up, login, and password reset with email verification.
  • Admin panel for managing users and logs.

• File Management

  • Upload and download files and folders.
  • Encrypted file storage using AES CBC mode.
  • Supports ZIP compression for folders.
  • Secure file integrity verification.

• Security & Encryption

  • AES (CBC mode) encryption for files.
  • RSA encryption for secure key exchange.
  • Secure login with hashed passwords.
  • IP banning for multiple failed login attempts.

• Graphical User Interface (GUI)

  • Tkinter-based interface for ease of use.
  • File explorer with pagination.
  • Admin dashboard for monitoring logs and managing users.

• Logging & Monitoring

  • Logs user activities (uploads, downloads, deletions).
  • Admins can view logs via the GUI.

Installation & Setup

1. Clone the repository

git clone https://github.com/Itapit/nimbus.git
cd nimbus

2. Install dependencies

Ensure you have Python installed, then install the required packages

3. Configure Email SMTP Settings

To enable email verification, update the email sender and password inside the server_utils.py file in the send_verification_email function:

# server_utils.py
sender = '[email protected]'  # Update this to your SMTP email
sender_password = 'your-password'  # Update this to your SMTP password

Note: This email must be linked to an SMTP service (e.g., Gmail, Outlook).

4. Run the server

Start the server using:

python Server.py

5. Run the client

python Client.py

Usage

1. User Operations

• Register/Login: Users must sign up with an email and password.
• Upload Files: Select files to upload securely.
• Download Files: Retrieve encrypted files from the cloud.
• Manage Files: Create folders, rename, and delete files.

2. Admin Features

• Manage Users: View and delete accounts.
• Monitor Logs: Track user activity logs.

Security Considerations

• Uses AES encryption for file security.
• Prevents directory traversal attacks.
• Secure password storage with hashing.
• Email verification for user authentication.
