The experience of using Node.JS with TypeScript, ts-node, and ESM is horrible.

There are countless guides of how to integrate them, but none of them seem to work.

Here's what worked for me.

Just add the following files and run npm run dev. You'll be good to go!

Setting up ssh public key authentication on macOS using a YubiKey 4

I largely followed Florin's blog post, but have a few notes to add regarding issues I encountered:

Basic setup notes

1. I used a YubiKey 4, while the blog describes using a YubiKey NEO. I'm sure a YubiKey 5 would also work. I'm also running macOS 10.13.6.
2. I installed GPGTools as recommended. However, as I'll note later, it seems that gpg-agent only automatically starts when gpg is used; for ssh, you'll need to ensure it's running.
3. Before generating your keys, decide what key size you want to use. If you run the list command inside gpg --edit-card, look for the Key attributes line to see what is currently selected. On my YubiKey 4, it defaulted to 2048 bits for all keys:

Key attributes ...: rsa2048 rsa2048 rsa2048

const ecurve = require('ecurve');
let secp256k1 = ecurve.getCurveByName('secp256k1');
const BigInteger = require('bigi');
const crypto = require('crypto');

const calculateHash = (R, P, message) => {
  const hashPreimage = Buffer.concat([R.getEncoded(true), P.getEncoded(true), Buffer.from(message, 'utf-8')]);
  return BigInteger.fromHex(crypto.createHash('sha256').update(hashPreimage).digest('hex')).mod(secp256k1.n);
};
