Native Secure Enclave backed ssh keys on MacOS

It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

Guide on how to create and set up a Dockerized web app using Django REST APIs and ReactJS

Hopefully this will answer "How do I setup or start a Django project using REST Framework and ReactJS?"

This is a guide to show you step by step how this can be setup. If you just want to get started, use the cookiecuter I set up cookiecutter-django-reactjs. It basically is a fork of pydanny's cookiecutter, just added the front-end stuff :).

I created this because it was SUCH a pain in the ass setting up a project using all the latest technologies. After some research, I figured it out and have it working. The repo that implements this is located here. Feel free to use it as a boilerplate ;)

Main features:

Django REST APIs

Prepare files & libraries

Download selenium standalone server from: http://goo.gl/rQhaxb, Create local folder at ~/selenium and copy or move jar to that path:

$ mkdir ~/selenium
$ cd ~/selenium
$ wget http://goo.gl/rQhaxb
$ mv selenium-server-standalone-2.49.1.jar ~/selenium/
