Updates

This document was published on 21.09.2015 for a freelance employer. Some changes since then (14.02.2016):

Koa.js no longer uses co-routines, it has switched to Babel's async/await. yield and await are used almost in the same way, so I see no point to rewrite the examples.

	#!/bin/sh
	# Decode a JWT from stdin and verify it's signature with the JWT issuer public key
	# Only RS256 keys are supported for signature check
	#
	# Put OAuth server public key in PEM format to /var/cache/oauth/$JWT_KID.key.pub.pem
	# You must create the folder first
	# $ sudo mkdir -p /var/cache/oauth/
	# To converted key from JWK to PEM use https://8gwifi.org/jwkconvertfunctions.jsp or https://keytool.online/
	# NOTE: For Google you can get the keys in PEM format via https://www.googleapis.com/oauth2/v1/certs
	# Decode the keys with decodeURIComponent()
