Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Abstraxn - Passkey Manager Package

The Passkey package provides utilities for handling WebAuthn passkeys, local storage, and signature extraction. It simplifies the process of creating, storing, and verifying passkeys using WebAuthn (Web Authentication) API, enabling secure authentication mechanisms in web applications.

Features

  • Passkey Creation: Generate passkeys using WebAuthn API.
  • Signature Extraction: Extract and decode signatures from authenticator responses.
  • Local Storage Management: Store and retrieve passkeys securely in local storage.
  • TypeScript Support: Written in TypeScript for type-safe usage.

Installation

Install the Passkey manager package from npm:

npm install @abstraxn/passkey-manager

Usage

Creating a Passkey

To create a passkey:

import { createPasskey, getPassKey, toLocalStorageFormat, isLocalStoragePasskey, extractSignature, extractClientDataFields } from '@abstraxn/passkey-manager''

async function main() {
  try {
    // Create a passkey
    const passkey = await createPasskey("username");

    console.log("Passkey created:", passkey);

    // Store passkey in local storage format
    const passkeyLocalStorageFormat = toLocalStorageFormat(passkey);
    console.log("Passkey stored in local storage format:", passkeyLocalStorageFormat);

  } catch (error) {
    console.error("Error creating passkey:", error);
  }
}

main();

Creating a Passkey

To retrieve a passkey:

const { getPassKey } = require('passkey');

async function main() {
  try {
    // Retrieve passkey
    const passkey = await getPassKey();

    console.log("Retrieved passkey:", passkey);

  } catch (error) {
    console.error("Error retrieving passkey:", error);
  }
}

main();

Additional Functions

  • extractSignature(signature: ArrayBuffer | Uint8Array): [bigint, bigint]: Extracts R and S values from an authenticator signature.
  • extractClientDataFields(response: AuthenticatorAssertionResponse): { field: string, clientDataJSON: string }: Extracts additional client data fields from an authenticator response.
