device-fingerprint

Generate a unique device fingerprint by collecting hardware identifiers from Windows devices.

Features

No Admin Rights Required - All collection methods work without elevated privileges
Pure Windows API - Uses only windows-sys for native API calls, with optional WMIC support
Stable & Reliable - Generates fingerprints based on Machine GUID and CPU characteristics
SHA256 Output - Produces a standard 64-character hash value

Installation

Add the dependency to your Cargo.toml:

[dependencies]

device-fingerprint = "0.1"

Quick Start

use device_fingerprint::{generate, verify};

fn main() {
    // Generate device fingerprint
    let fingerprint = generate();
    println!("Device Fingerprint: {}", fingerprint);

    // Verify device fingerprint
    if verify(&fingerprint) {
        println!("Fingerprint verification passed");
    }
}

Main Functions

Function	Description
`generate()`	Generate device fingerprint, returns 64-character SHA256 hash
`verify(expected)`	Verify if the fingerprint matches the current device

Collector Module

Function	Description
`collectors::machine_guid()`	Get Windows Machine GUID
`collectors::cpu_id()`	Get CPU vendor and feature information
`collectors::wmic_uuid()`	(Optional) Get SMBIOS UUID via WMI

Collected Information

Component	Source	Stability
Machine GUID	Registry `HKLM\SOFTWARE\Microsoft\Cryptography`	Changes after OS reinstall
CPU ID	CPUID instruction	Changes after CPU replacement
