seed-fingerprint

seed-fingerprint is a library that creates a hash that can identify users based on seeds.

The library has gained a lot of inspiration from the https://github.com/fingerprintjs/fingerprintjs, and https://github.com/pjanczyk/simple-fingerprint libraries. Thank you.

For example, you may want to use fingerprints instead of tokens, but the user's finger prints can get the same value on all websites. It is not good for security because the attacker can steal the user's finger print.

seed-fingerprint uses seeds to generate a hash that can identify the user.

Node.js

import { create } from 'seed-fingerprint';

const seed = 'hello';
const fingerprint = create(seed);

const id = await fingerprint.get();

Browser (umd)

// html load
<script src="https://cdn.jsdelivr.net/npm/[email protected]/build/umd/index.min.js"></script>

// script
const seed = 'hello';
const fingerprint = window.SeedFingerprint.create(seed);

const id = await fingerprint.get();

Browser (esm)

<script type="module">
import { create } from 'https://cdn.jsdelivr.net/npm/[email protected]/build/esm/index.min.js'

const seed = 'hello';
const fingerprint = create(seed);

const id = await fingerprint.get();
</script>

fingerprint has the following components: Each component returns a promise.
