hw-fingerprint

Hardware-based fingerprint for Node and Electron

About

This library provides a fingerprint() function that produces a 512-bit signature based on the host machine's hardware information, suitable for use in Electron or Node client apps that require authentication against a server.

It uses information provided by Node's OS module and systeminformation library and has no other dependencies.

Usage

fingerprint() is always asynchronous and returns a Node Buffer. The returned promise is internally cached, so the actual implementation gets called just once.

  const { fingerprint } = require('hw-fingerprint')

  // with async/await
  async function(){
    const signature = await fingerprint()
    // do something
  }

  // with promises
  function(){
    fingerprint.then(function(signature){
      // do something
    })
  }
