Certificate demos using docker, nginx, openssl, curl

Figuring out how certificates work, with practical examples. The days I spent on this saved me a few hours of reading :)

Required knowledge

It will probably help to know some docker basics. Hopefully this should suffice for the rest:

• nginx: a HTTP server / reverse-proxy
• openssl: a cryptography tool that can create certificates, and do many other things related to certificates and keys
• curl: a terminal-based HTTP client

Before you start

Install docker.

If running in msys/windows, run source 00_init_env.sh. This project was developed on Windows, so that'll show in the path names etc. Just be aware you may need to tweak things a bit to run in other OSs.

Run the demos

Proceed through each numbered folder to see different server/auth etc. configurations. Each folder has a readme with details about what's happening.

todo

• tldr version of all this for ppl like me
• proof-read all docs, test all scripts, rename stuff if needed (eg. 'certificate.crt')
• add pictures
