Creating Oauth Test in Github/WAN

Overview + initial

The first step is to create a test Oauth app on my WAN box to then be eventually done in production on AWS

• Under Settings->Developer Settings, Create an OAuth Application in Github which will generate
• A client ID (this is public)
• A client Secret (guard this like a private key)
• You will need to specify the Home Page and Callback URL of your application

sudo apt-get update -y

Flask

apt install python3-pip build-essential libffi-dev python3-dev python3-setuptools libssl-dev
apt install python3.10-venv
pip3 install virtualenvwrapper

• Create a directory called /oauthlab/ in the ~ directory

vim create ~/oauthlab/creds.json

{
    "client_id":"potato",
    "client_secret":"carrot",
    "authorization_base_url":"https://github.com/login/oauth/authorize",
    "token_url":"https://github.com/login/oauth/access_token"
}

• Replace potato with client id found when making oauth app
• Replace carrot with client secret found when making oauth app

vim create ~/oauthlab/webapp.py
webapp.py code

python3 -m venv ~/oauthlab/venv
source ~/oauthlab/venv/bin/activate

Now install requirements

pip3 install wheel
pip3 install Flask
pip3 install pyOpenSSL
pip3 install requests_oauthlib

Start it

python3 ~/oauthlab/webapp.py

Navigate to https://127.0.0.1:5000

AWS

Essentially the same exact steps but the main change is that you are going to set this as your ec2 pub address

• Use a ubuntu 22.04 free Ec2 instance for this

Reflection

Overall I found this lab to be enjoyable as I got to experiment with Oauth and combine it with AWS, this will help me in the future if I end up going towards aws or cloud based environments
