Node.js TLS plain TLS sockets

This guide shows how to set up a bidirectional client/server authentication for plain TLS sockets.

Generate a Certificate Authority:

openssl req -new -x509 -days 9999 -keyout ca-key.pem -out ca-crt.pem

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git

	* Play's Scala WS library is very very cool. Provides you with plenty niceties.
	* See more: https://www.playframework.com/documentation/2.3.x/ScalaWS

	* Unfortunately it by default requires a Play application context.
	* But you do not necessarily always want that.
