How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

Lets get some context first.

	#!/usr/bin/env python3
	"""Command generator for setting DHCP Option 119

	This script converts the specified domain names to DHCP Option 119
	(Domain Search Option) and prints commands for various DHCP servers.

	USAGE:
	./dhcp_option119.py DOMAIN ...

	EXAMPLE:

	#!/bin/bash

	usage ()
	{
	cat <<UsageHERE
	boot2docker-fwd -- Helper function to quickly manage port forwards between the boot2docker-vm and the host
	Usage: boot2docker-fwd [ -n RULE_NAME ] [ -h HOST_PORT ] [ -p {tcp\|udp} ] [ -i HOST_IP ] GUEST_PORT
	or boot2docker-fwd -d RULE_NAME
	or boot2docker-fwd -l
	or boot2docker-fwd -A
