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.

Operator Overrides

I absolutely love using operator overrides in low-level objects because it can make the caller's use case WAY more intuitive. There are certainly some pitfalls though.

If you're overriding __getitem__ and __setitem__ to make an object more dictionary-like, make sure to also override __iter__ OR __contains__ since they're called to handle membership tests like in and not in. (ref: https://docs.python.org/3/reference/expressions.html#membership-test-operations)

Enums

Enums can be a little tedious in Python, but there are a few things I try to do to streamline usage:

Keybase proof

I hereby claim:

I am svvitale on github.
I am svvitale (https://keybase.io/svvitale) on keybase.
I have a public key ASDTmkxAdl96XWG71bZe4C58UsDKQXlt8DaltryKd8ALYAo

To claim this, I am signing this object:

	using DYMO.Label.Framework;

	namespace ConsoleApp1
	{
	class Program
	{
	static void Main(string[] args)
	{
	Printers printers = new Printers();
