DZap: Secure Drive Wiper

DZap is a cross-platform utility designed to securely sanitize storage media (HDDs, SSDs, NVMe, USBs) to NIST 800-88 standards.

WARNING: This software is designed to permanently and irretrievably destroy data. Use with extreme caution. The developers are not responsible for accidental data loss.

Key Features

• Modern Tech Stack: Built with Electron, React, & Tailwind CSS for a responsive UI, backed by Go for high-performance hardware interaction.
• NIST 800-88 Compliance:
  • Clear: 1-pass and 3-pass overwrite algorithms for HDDs.
  • Purge: Firmware-based ATA Secure Erase and NVMe Format for modern SSDs.
• Secure Architecture: Uses a Privileged Helper pattern. The UI runs as a standard user, while the backend runs securely via Linux PolicyKit (pkexec) only when necessary.
• Certified Destruction: Generates a verifiable HTML/PDF certificate upon successful completion.
• Hot-Plug Support: Automatically detects drives connected via USB or SATA/NVMe interfaces.

Prerequisites

Before installing, ensure your Linux system has the following dependencies:

• Runtime Tools: smartmontools, hdparm, nvme-cli, polkit
• Build Tools: go (v1.21+), npm / node, gcc
• AI Runtime: libonnxruntime (often available as onnxruntime or libonnxruntime-dev) (Disabled for now)

Arch Linux:

sudo pacman -S go npm smartmontools hdparm nvme-cli onnxruntime

Ubuntu/Debian:

sudo apt install golang nodejs npm smartmontools hdparm nvme-cli libonnxruntime-dev

Installation & Build

Because DZap uses a system-level backend service, installation is a two-step process.

1. Build the Application

Clone the repository and build the source code.

npm install
npm install cross-env --save-dev
npm run start:frontend

In another terminal run:

cd server
sudo go run .

2. Install the Backend Helper

Run the provided installer script. This copies the Go binary to a secure system location (/usr/local/bin) and installs the PolicyKit rules allow the UI to communicate with it.

sudo ./install.sh

---

Usage

Once installed, you can run the application like any other Linux program.

1. Navigate to the dist/ folder (or wherever you moved the AppImage).
2. Run the application:

   ./DZap\ Secure\ Wiper-1.0.0.AppImage

   (Note: You do NOT need sudo to run the AppImage).
3. When the backend needs to start (usually immediately upon launch), the system will prompt you for your password via a secure GUI dialog.

Development

For developers contributing to DZap, use the development mode which enables hot-reloading.

Recommended Workflow:

1. Terminal 1 (Backend):

   cd server
   sudo go run .

2. Terminal 2 (Frontend):

   npm run start:frontend
