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 🙏

lib-dqx

The library that allows to build an application that interacts with DQx tags.

Setting up

Install rn-nodeify

See rn-nodeify docs page for more details.

rn-nodeify --install stream,buffer,events,assert --hack

Install react-native-nfc-manager

npm i --save react-native-nfc-manager

Then follow the installation guide in react-native-nfc-manager docs page.

Install @beechat-network/lib-dqx

npm i --save @beechat-network/lib-dqx

Library usage

This library exports the following functions:

dilithiumGenKeyPair

Generate new Dilithium2 key pair.

declare async function dilithiumGenKeyPair({randomBytes: (size: number) => Buffer}): {secretKey: Buffer, publicKey: Buffer};

dilithiumSign

Sign 32 byte challenge using the provided secretKey.

declare async function dilithiumSign({secretKey: Buffer, challenge: Buffer}): Buffer;

dilithiumVerifySig

Verify Dilithium2 signature against the provided 32 byte challenge and public key.

Function prototype:

declare async function dilithiumVerifySig({publicKey: Buffer, challenge: Buffer, signature: Buffer}): boolean;

Function returns true if the signature validation was successful or false otherwise.

Example usage:

import {
  dilithiumVerifySig
} from 'lib-dqx';

let publicKey = Buffer.from("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", "hex");

dqxPerformNFC

Start NFC scan and perform an operation with the Dilithium tag.

Function prototype:

declare async function dqxPerformNFC(nfcAction: function, {setWorkStatusMessage: function}, options: object): object;

Where:

  • nfcAction - one of the functions listed above (signChallenge, eraseKeys etc.);
  • {setWorkStatusMessage} - an object containing callbacks:
    • setWorkStatusMessage(text: string): null - a callback that is called whenever there is some status update, the status update could be displayed in the UI;
  • options - command-specific options;
