Get-device-signature NPM

get-device-signature/getHashedString

A lightweight library to generate a unique device signature using browser attributes and SHA-256 hashing.

✨ Features

✅ Generates a unique, consistent device signature
✅ Uses SHA-256 hashing for security
✅ Works in modern browsers
✅ Zero dependencies

📦 Installation

Install the package via npm:

npm install get-device-signature

🚀 Usage

✅ Get a SHA-256 Hash of Any String

import { getHashedString } from "get-device-signature";

(async () => {
const hash = await getHashedString("Hello World");
console.log(hash); // Outputs a SHA-256 hashed string
})();

✅ 2. Generate a Unique Device Signature

import { getDeviceSignature } from "get-device-signature";

(async () => {
  const signature = await getDeviceSignature();
  console.log("Device Signature:", signature);
})();

This function collects browser attributes such as:

userAgent platform language hardwareConcurrency screenResolution Then, it hashes them into a unique identifier.

🛠️ How It Works

Collects browser attributes (User-Agent, OS, Screen Size, etc.). Converts them into a JSON string. Hashes the string using SHA-256. Returns a unique device signature. This makes it useful for identifying devices without tracking users.
