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 🙏

Message Signing

This is a library that implements the CIP-0008 message signing spec for the Cardano blockchain.

The library is composed of structs for (de)serializing the CBOR defined in CIP-0008/COSE which lays at the core of the protocol, mostly defined in lib.rs, as well as many helper utilities for more specific cases useful to CIP-0008. These are mostly in builders.rs for building the CBOR structures specific to certain algorithms.

NPM packages

Building

It can be used from both rust or compiled to wasm as all public code works with wasm-bindgen via wasm-pack.

There are no rust crates/npm packages uploaded yet, but these will come in the future.

In the meantime to build a wasm package we can run one of

  • npm run rust:build-nodejs for nodejs targeted wasm
  • npm run rust:build-browser for browser targeted wasm
  • npm run asm:build for conversion for asm.js

and for use from rust simply use the lib that resides in /rust/.

Example Usage

It is important to read the CIP-0008 spec to properly understand how to use this library. As per CIP-0008/COSE, signing is done via constructing a SigStructure and then signing this with the proper keys. This can be simplified via the use of the COSESignBuilder (for multiparty signing) / COSESign1Builder (for single signer) builders. Encryption is not yet supported by this library but will be in the future. An example node.js (wasm option) project that signs a message with a Cardano address exists in the /example/ directory which has detailed comments describing each step.
