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.

Pair programming with Tmux

Using the same user

User 1

SSH into the box
```
 user1@user1-machine$ ssh user@host
```

Generate private key (.key)

# Key considerations for algorithm "RSA" ≥ 2048-bit
openssl genrsa -out server.key 2048

# Key considerations for algorithm "ECDSA" ≥ secp384r1
# List ECDSA the supported curves (openssl ecparam -list_curves)

	# Add the following 'help' target to your Makefile
	# And add help text after each target name starting with '\#\#'

	help: ## Show this help.
	@fgrep -h "##" $(MAKEFILE_LIST) \| fgrep -v fgrep \| sed -e 's/\\$$//' \| sed -e 's/##//'

	# Everything below is an example

	target00: ## This message will show up when typing 'make help'
	@echo does nothing

	Key-Type: 1
	Key-Length: 2048
	Subkey-Type: 1
	Subkey-Length: 2048
	Name-Real: Root Superuser
	Name-Email: [email protected]
	Expire-Date: 0

	USAGE="Attach to Docker Container
	--------------------------
	Attach to Docker Container even if the container does not run
	ssh daemon. This is accomplished by using linux containers
	directly via 'nsenter' (see http://bit.ly/docker_nsenter).
	To install 'nsenter', just execute:

	$ docker run -v /usr/local/bin:/target jpetazzo/nsenter

	package tar_helper

	import (
	"archive/tar"
	"compress/gzip"
	"errors"
	"fmt"
	"io"
	"io/ioutil"
	"os"

	// A small SSH daemon providing bash sessions
	//
	// Server:
	// cd my/new/dir/
	// #generate server keypair
	// ssh-keygen -t rsa
	// go get -v .
	// go run sshd.go
	//
	// Client:

	# Set variables in .bashrc file

	# don't forget to change your path correctly!
