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 🙏

Keychain Manager

CircleCI npm npm npm Slack

A key system based around accounts that each have hierarchical deterministic (HD) keychains with ECDSA keypairs (the ones Bitcoin uses).

Getting started

$ npm install keychain-manager
var PrivateKeychain = require('keychain-manager').PrivateKeychain,
    PublicKeychain = require('keychain-manager').PublicKeychain

Private Keychain

var masterPrivateKeychain = new PrivateKeychain()

var accountNumber = 0,
    accountPrivateKeychain = masterPrivateKeychain.account(accountNumber),
    accountPublicKeychain = accountPrivateKeychain.publicKeychain(),

var childNumber = 2,
    childPrivateKeychain = masterPrivateKeychain.child(childNumber)

A master private keychain is the highest level abstraction of keys. It represents the root or master private key for the application and/or device. Account-specific private keychains can be derived from it, which can then be used to derive account-specific public keychains.

Note that knowledge of the master private key of an account keychain derived from the master private keychain does not provide knowledge of the key of the master keychain.

var childKeyName = 'blockstack.org'

var chainPathHash = accountPrivateKeychain.secretHash(childKeyName),
    privateKey = accountPrivateKeychain.descendant(chainPathHash).privateKey()

A private keychain is a collection of private keys with a chain-specific master key or "ancestor" key that helps derive all of the child keys.

An account private keychain is derived from a master private keychain through hardening in the key derivation process. A child private keychain, meanwhile uses hardened key derivation. It is recommended that one use at least one level of accounts derived from the master private keychain. This adds a nice capability where an entirely new keychain can be issued if the master key of a particular keychain is ever compromised.

Note that every child private key in a keychain can be traced back to the ancestor key in the chain. That said, with a chain path with enough entropy, it would be intractable to brute-force the path from the child private key to the ancestor private key.

Public Keychain

var publicKey = publicKeychain.publicKey(),
    address = publicKeychain.address(),
    chainPathHash = 'bd62885ec3f0e3838043115f4ce25eedd22cc86711803fb0c19601eeef185e39',
    descendantPublicKey = publicKeychain.decendant(chainPathHash).publicKey()

A public keychain is the public equivalent of a private keychain, where every public key has a corresponding private key in the corresponding keychain.

Note that every child public key in the public keychain can be traced back to the ancestor public key in the chain. But again, if the chain path is random and long enough, it would be intractable to brute-force the path from the child public key to the ancestor public key.
