How to setup your own CA with OpenSSL

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

First things first

Lets get some context first.

	#!/bin/bash
	#
	# Do a ping and output results as CSV.
	#
	# [email protected]
	# 2011-12-23
	#

	if [ $# -lt 1 ]; then
	echo "Usage: $0 [--add-timestamp] <ping host>"

	# put this in your .bash_profile
	if [ $ITERM_SESSION_ID ]; then
	export PROMPT_COMMAND='echo -ne "\033];${PWD##*/}\007"; ':"$PROMPT_COMMAND";
	fi

	# Piece-by-Piece Explanation:
	# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
	# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too
	# the $PROMPT_COMMAND environment variable is executed every time a command is run
	# see: ss64.com/bash/syntax-prompt.html

	#!/bin/sh

	# Script finds AWS Security Groups with potentially unsafe rules and lists instances that use such security groups.
	#
	# Unsafe security group rules are:
	# 1. open to the world (0.0.0.0/0),
	# 2. not restricted to another security group,
	# 3. not use safe ports (22,80,443; you can set SAFE_PORTS environment variable to override).
	#
	# To run this script:

	#!perl

	use strict;
	use warnings;
	use Parallel::ForkManager;
	use POSIX;
	use String::Random;

	my $c_start = 1;
	my $c_end = 64;

	#!/bin/bash
	# Sometimes you need to move your existing git repository
	# to a new remote repository (/new remote origin).
	# Here are a simple and quick steps that does exactly this.
	#
	# Let's assume we call "old repo" the repository you wish
	# to move, and "new repo" the one you wish to move to.
	#
	### Step 1. Make sure you have a local copy of all "old repo"
	### branches and tags.
