Green Health Cert Generator and Verifier Lib

Introduction

This lib is a helper to be able to work with green health cert easily from Javascript

Usage

const {encode, verify } = require('hcert')

const payload = { user: { name: 'Tolvan Tolvansson' } }
const signer = { ... }
const verifier = { ... }

const headers = {
    p: { alg: 'ES256' },
    u: { kid: '11' }
}

const qr = await generate(payload, headers, signer)
// 6BFOXN*TS0BI$ZD1TH-KK.QOVTQT*QO$GIGF9LNG$G MVS$CQDF 420DNK:7NQO9497WV:XM*8N%7KOCM/ZLV5QKDGVALV*T-$FGG4O3WM3NH0CF4E2C74MGU06*43I VW0V+RDNHR/SL/1UX0G0AR*-PDAU9CR$%I+-FL50/.4U1

const decoded = await verify(qr, verifier)
// { user: { name: 'Tolvan Tolvansson' } }
