A simple HTTPS server in Python

"""
A simple HTTPS server

Generate cert and key with:

```sh
openssl req -newkey rsa:4096 -x509 -sha256 -days 3650 -nodes -subj '/CN=localhost' -out ./ssl/cert.pem -keyout ./ssl/key.pem
```

Test with httpie:

```sh
http -v --verify no https://localhost:42999/hello
```
