🔒 CyberDrive - Encrypted Virtual Disk Manager

A modern, secure virtual disk encryption tool for Windows that creates and manages encrypted virtual hard drives (VHDs) with AES-256 encryption and secure file deletion capabilities.

✨ Features

• 🔐 AES-256 Encryption - Military-grade encryption using PBKDF2 with 100,000 iterations
• 💾 Virtual Hard Drives - Create expandable VHD files that mount as regular drives
• 🗑️ Secure File Deletion - Multi-pass secure deletion with cryptographically random data
• 🎨 Modern UI - Clean, dark-themed interface with gradient buttons and smooth animations
• ⚡ Fast Operations - Optimized for quick vault creation and mounting
• 🔒 Password Protection - Strong password-based vault security

🚀 Quick Start

Prerequisites

• Windows 10/11
• .NET Framework 4.7.2 or higher
• Administrator privileges (required for VHD operations)

Usage

1. Create a Vault

   • Enter a unique vault name
   • Set a strong password
   • Click "🔒 Create Encrypted Vault"

2. Unlock a Vault

   • Enter the vault name and password
   • Click "🔓 Unlock Vault"
   • The vault will appear as a new drive letter

3. Lock a Vault

   • Click "🔐 Lock Vault" to safely unmount
   • All data is automatically encrypted

4. Check Mounted Vaults

   • View all currently mounted CyberDrive vaults
   • See available space for each vault

🏗️ Building from Source

Requirements

• Visual Studio 2019 or later
• .NET Framework 4.7.2 SDK
• Windows SDK

Build Steps

git clone https://github.com/yourusername/cyberdrive.git
cd cyberdrive

Open CyberDrive.sln in Visual Studio and build the solution (Ctrl+Shift+B).

🔧 Technical Details

Architecture

• VHD Management - Uses Windows diskpart utility for virtual disk operations
• Encryption - AES-256-CBC with PBKDF2-SHA256 key derivation
• File System - NTFS with "CyberDriveVault" volume label
• Secure Deletion - 3-pass random data overwrite by default

Security Features

• PBKDF2 key stretching with 100,000 iterations
• Random salt generation for each encryption operation
• Secure random IV for each encrypted file
• Memory protection for sensitive operations
• Multi-pass deletion to prevent data recovery

⚠️ Important Security Notes

• Administrator Rights: Required for all VHD operations (create, mount, unmount)
• Password Strength: Use strong, unique passwords for each vault
• Backup: Keep secure backups of important vaults
• Memory: Sensitive data may remain in memory - reboot after handling critical data
