Despite this PR (only) being ~200 lines containing mostly code copied from another repo, there is a lot going on here. For the sake of making it both easier to review and to remember some of these things in the future by referring back to this PR, I've documented a lot of noteworthy things with section headers below. With that said, it's probably not necessary to read each section unless you're interested in that topic. The most noteworthy thing for the reviewer is **this PR should be merged and not squashed** to preserve authorship. To merge this code, once we're happy with this PR, I'll probably open a new PR squashing any commits I make in response in review comments back into a single commit to try to keep history somewhat clean. To help prevent this PR from being accidentally squashed, I'm making this a draft PR for now. ### Git history of https://github.com/basak/certbot-snap-build I think it is worth preserving the git history of https://github.com/basak/certbot-snap-build that this PR is based on in this repo to help us track why things were done a certain way. To do this while keeping our git history somewhat clean, I took the approach described at https://stackoverflow.com/questions/1425892/how-do-you-merge-two-git-repositories/21495718#21495718 to move all history of https://github.com/basak/certbot-snap-build into a `snap` directory. I then squashed all commits so that sequential commits from the same author are one commit. I probably could have reordered commits to try and squash things a little more, but I personally don't think it's worth the trouble. Finally, I merged this rewritten history into this branch of the Certbot repo. The contents of the `snap` directory are identical to the current contents of https://github.com/basak/certbot-snap-build before my final commit in this PR which makes the changes to make things work in this repo. ### Travis stages This is described in general at https://docs.travis-ci.com/user/build-stages/, but I don't think we should deploy the snap if any of our tests are failing. To accomplish this, I created a "Snap" stage that builds, tests, and deploys the snap which is only executed after a "Test" stage that contains all of our other tests. The "Snap" stage will not run until the "Test" stage completes successfully. ### snap/local This directory is ignored by `snapcraft` which I think makes it a good place to store `snap` specific scripts like `build_and_install.sh`. See https://bugs.launchpad.net/snapcraft/+bug/1792203 for more info. ### Why remove certbot-compatibility-test from apacheconftest toxenvs? Because it's not used. In theory, it could go in its own PR, but it'll create merge conflicts with this one so I'd personally prefer to include this simple change in this PR as well. ### Checklist for landing this PR - [x] Squash all of my commits into one commit - [x] Update the release instructions to have to move the snap to the beta channel - [x] Shut down Robie's nightly builds probably by updating his repo to say that the code has moved here and deleting everything
Certbot is part of EFF’s 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 Let’s 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 Let’s 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, so there’s no need to arrange payment.
How you use Certbot depends on the configuration of your web server. The best way to get started is to use our interactive guide. It generates instructions based on your configuration settings. In most cases, you’ll need root or administrator access to your web server to run Certbot.
Certbot is meant to be run directly on your web server, not on your personal computer. If you’re using a hosted service and don’t 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 Let’s Encrypt.
Certbot is a fully-featured, extensible client for the Let's Encrypt CA (or any other CA that speaks the ACME protocol) that can automate the tasks of obtaining certificates and configuring webservers to use them. This client runs on Unix-based operating systems.
To see the changes made to Certbot between versions please refer to our changelog.
Until May 2016, Certbot was named simply letsencrypt or
letsencrypt-auto, depending on install method. Instructions
on the Internet, and some pieces of the software, may still refer to
this older name.

How to run the client
The easiest way to install and run Certbot is by visiting certbot.eff.org, where you can find the correct instructions for many web server and OS combinations. For more information, see Get Certbot.
Understanding the client in more depth
To understand what the client is doing in detail, it's important to understand the way it uses plugins. Please see the explanation of plugins in the User Guide.

System Requirements
See https://certbot.eff.org/docs/install.html#system-requirements.
Current Features
- Supports multiple web servers:
- apache/2.x
- nginx/0.8.48+
- webroot (adds files to webroot directories in order to prove control of domains and obtain certs)
- standalone (runs its own simple webserver to prove you control a domain)
- other server software via 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.
- Adjustable RSA key bit-length (2048 (default), 4096, ...).
- Can optionally install a http -> https redirect, so your site effectively runs https only (Apache only)
- Fully automated.
- Configuration changes are logged and can be reverted.
- Supports an interactive text UI, or can be driven entirely from the command line.
- Free and Open Source Software, made with Python.
