Brad WarrenandGitHub 513190afe0 don't use snakeoil certs in nginx (#10465)
this PR finally removes all uses of self-signed certificates from
certbot-nginx

i plan to create one last PR related to this deprecating
`acme.crypto_util.make_self_signed_cert` and moving the function to
certbot-compatibility-test which is the only place it's currently used

i think we could also do additional refactoring in certbot-nginx by
moving the _make_server_ssl call out of choose_or_make_vhost and make
deploy_cert responsible for calling it if the returned vhosts aren't
ssl. in this case, we could then skip updating cert and key directives a
second time as this is duplicate work if we just made the server ssl

i considered doing this, but it's a bigger refactor, breaks more tests,
and i'm not sure it really buys us much so i skipped it. i could take
this on or create an issue for it if you think it's important for us to
do for some reason tho ohemorange

Certbot is part of EFFs effort to encrypt the entire Internet. Secure communication over the Web relies on HTTPS, which requires the use of a digital certificate that lets browsers verify the identity of web servers (e.g., is that really google.com?). Web servers obtain their certificates from trusted third parties called certificate authorities (CAs). Certbot is an easy-to-use client that fetches a certificate from Lets Encrypt—an open certificate authority launched by the EFF, Mozilla, and others—and deploys it to a web server.

Anyone who has gone through the trouble of setting up a secure website knows what a hassle getting and maintaining a certificate is. Certbot and Lets Encrypt can automate away the pain and let you turn on and manage HTTPS with simple commands. Using Certbot and Let's Encrypt is free.

.. _installation:

Getting Started
---------------
The best way to get started is to use our `interactive guide <https://certbot.eff.org>`_. It generates instructions based on your configuration settings. In most cases, youll need `root or administrator access <https://certbot.eff.org/faq/#does-certbot-require-root-administrator-privileges>`_ to your web server to run Certbot.

Certbot is meant to be run directly on your web server on the command line, not on your personal computer. If youre using a hosted service and dont have direct access to your web server, you might not be able to use Certbot. Check with your hosting provider for documentation about uploading certificates or using certificates issued by Lets Encrypt.

Current Features
=====================

* Supports multiple web servers:

  - Apache 2.4+
  - nginx/0.8.48+
  - webroot (adds files to webroot directories in order to prove control of
    domains and obtain certificates)
  - standalone (runs its own simple webserver to prove you control a domain)
  - other server software via `third party plugins <https://certbot.eff.org/docs/using.html#third-party-plugins>`_

* The private key is generated locally on your system.
* Can talk to the Let's Encrypt CA or optionally to other ACME
  compliant services.
* Can get domain-validated (DV) certificates.
* Can revoke certificates.
* Supports ECDSA (default) and RSA certificate private keys.
* Can optionally install a http -> https redirect, so your site effectively
  runs https only.
* Fully automated.
* Configuration changes are logged and can be reverted.
