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 🙏

HTTP Message Signatures

This library provides a simple way to implement the IETF HTTP Message Signatures draft standard for signing and verifying the integrity and authenticity of HTTP requests and responses.

HTTP Message Signatures provide a secure way to ensure that HTTP messages exchanged between clients and servers are authentic and have not been tampered with during transit.

The library does not provide any cryptographic functionality, but instead relies on the user to provide Signer and Verify callback functions for signing and verifying messages, respectively. This allows you to choose your preferred cryptographic library and signing algorithm.

This library can be used both in Node.js and the browser, and the documentation provides platform-specific examples for each environment.

Usage

Signing

import { sign } from '@ltonetwork/http-message-signatures';

const signer = { 
  keyid: 'test-key',
  alg: 'hmac-sha256',
  sign: (data) => {
    // ... Sign the data using your preferred cryptographic library
  }
};

const request = {
  method: 'POST',
  url: 'https://example.com/api/data',
  headers: {
    'Content-Type': 'application/json',
    'Digest': 'sha-256=4VYMyeX0tNLQ7opuAJeMECP3HgfLswAG3n+IqQprO0Q=',
  }
};


(async () => {
    const signedRequest = await sign(request, { signer });
    // ... Send the signed request to the server
})();

Verification

import { verify } from '@ltonetwork/http-message-signatures';

const verifyCallback = async (data, signature, params) => {
  const account = await getAccount(params.keyid);

  // ... Verify the signature using your preferred cryptographic library
  if (!valid) throw new Error('Invalid signature');
  
  return account;
};


const request = {
  method: 'POST',
  url: 'https://example.com/api/data',
  headers: {
    'Content-Type': 'application/json',
    'Digest': 'sha-256=4VYMyeX0tNLQ7opuAJeMECP3HgfLswAG3n+IqQprO0Q=',
    'Signature': 'keyid="test-key",algorithm="hmac-sha256",signature="base64encodedsignature"',
    'Signature-Input': 'sig1=("@method" "@path" "@authority" "content-type" "digest");created=1618884475'
  }
};

(async () => {
  try {
    const verified = await verify(request, verifyCallback);
    console.log('Verification succeeded');
  } catch (err) {
    console.error('Verification failed:', err.message);
  }
})();
