Ben Thorner e2cf3e2c70 Support registering a new authenticator
This adds Yubico's FIDO2 library and two APIs for working with the
"navigator.credentials.create()" function in JavaScript. The GET
API uses the library to generate options for the "create()" function,
and the POST API decodes and verifies the resulting credential. While
the options and response are dict-like, CBOR is necessary to encode
some of the byte-level values, which can't be represented in JSON.

Much of the code here is based on the Yubico library example [1][2].

Implementation notes:

- There are definitely better ways to alert the user about failure, but
window.alert() will do for the time being. Using location.reload() is
also a bit jarring if the page scrolls, but not a major issue.

- Ideally we would use window.fetch() to do AJAX calls, but we don't
have a polyfill for this, and we use $.ajax() elsewhere [3]. We need
to do a few weird tricks [6] to stop jQuery trashing the data.

- The FIDO2 server doesn't serve web requests; it's just a "server" in
the sense of WebAuthn terminology. It lives in its own module, since it
needs to be initialised with the app / config.

- $.ajax returns a promise-like object. Although we've used ".fail()"
elsewhere [3], I couldn't find a stub object that supports it, so I've
gone for ".catch()", and used a Promise stub object in tests.

- WebAuthn only works over HTTPS, but there's an exception for "localhost"
[4].  However, the library is a bit too strict [5], so we have to disable
origin verification to avoid needing HTTPS for dev work.

Setting up

Python version

At the moment we run Python 3.6 in production.

NPM packages

brew install node

NPM is Node's package management tool. n is a tool for managing different versions of Node. The following installs n and uses the long term support (LTS) version of Node.

npm install -g n
n lts

environment.sh

In the root directory of the application, run:

echo "
export NOTIFY_ENVIRONMENT='development'
export FLASK_APP=application.py
export FLASK_ENV=development
export WERKZEUG_DEBUG_PIN=off
"> environment.sh

AWS credentials

To run parts of the app, such as uploading letters, you will need appropriate AWS credentials. See the Wiki for more details.

To run the application

# install dependencies, etc.
make bootstrap

# run the web app
make run-flask

Then visit localhost:6012.

To test the application

# install dependencies, etc.
make bootstrap

make test

Common tasks

Updating application dependencies

requirements.txt is generated from the requirements.in in order to pin versions of all nested dependencies. If requirements.in has been changed, run make freeze-requirements to regenerate it.

Automatically rebuild the frontend assets

If you want the front end assets to re-compile on changes, leave this running in a separate terminal from the app

    npm run watch
