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 🙏

Readme

react-native-fast-crypto

This library implements fast, fully native crypto routines for React Native under iOS and Android. Fully built binaries are committed for both platforms but can also be built from scratch.

Getting started

This library directly supports React Native v0.60+ with autolinking. Simply add react-native-fast-crypto to your application, and React Native will link the necessary native modules into your app.

npm install react-native-fast-crypto --save

Usage

import { scrypt } from 'react-native-fast-crypto';

const data = Uint8Array.from([1, 250, 3, 4, 34, 64, 39, 43, 12])
const salt = Uint8Array.from([45, 124, 45, 29, 172, 238, 35])

const result: Uint8Array = await crypto.scrypt(data, salt, 16384, 8, 1, 32)
console.log(result)

Build libsecp256k1 from scratch (optional)

The build process requires several pieces of software to be installed on the host system:

  • autoconf
  • automake
  • git
  • libtool

To install these on the Mac, please use Homebrew:

brew install autoconf automake git libtool

If you are building for iOS, you also need a working installation of the XCode command-line tools.

Finally, run ./build-secp256k1.sh
