# DEMOS2

Prototype Django-based e-voting application, to demonstrate DEMOS2's client-side encryption e-voting.

The previous repository for DEMOS2 by Carey Williams can be found at: https://github.com/CareyJWilliams/DEMOS2

### Main Application Dependencies

    Python: Version 2.7 (Anything higher than this will not currently work)
    Python packages: Specified in 'requirements.txt' - PyCharm will detect these dependencies and offer installation
    MySQL Server: Community Ed will do - initialised with legacy password authentication
    New MySQL DB User: Default username and password specified in 'aullauthdemo/settings.py'
    New MySQL DB: demos2 (also specified in 'aullauthdemo/settings.py') - make sure to set the charset to UTF8

Finally, with all the above dependencies in place, you can simply issue the following command to initialise the DB:

    python manage.py migrate

'aullauthdemo/settings.py' specifies the Google reCAPTCHA site key and private key which will need changing when deployed
onto a new domain. There is also a DOMAIN setting within the file that needs updating during deployment as things
like email functionality depend on this setting for correct URL generation during event preparation etc. 

Emails from the application are currently sent from the following email account which can be updated within the settings:

    demos2.no.reply@gmail.com

### NodeJS Dependencies

The Node.js crypto server depends on the milagro-crypto-js and express modules. A package.json file can be found in the 
Node/ directory with these dependency requirements and therefore from this folder you can run:

    npm install

Once the dependencies have been installed, you can then run the node server as per the below instructions.

### Step 1: Running the Python app and creating a new user account

You can run the server with the following command:

    python manage.py runserver

The application will then be available at:

    127.0.0.1:8000

You can then click on 'Join' to create a new user account. Currently, a server error is thrown when you create a new
email account saying something like 'Too Many Attempts'. Rest assured that the account will have been created. Navigate
back to the home page and you should be able to log in. This will hopefully be fixed in a future version.

### Step 2: Running Celery

Celery is used to run tasks asynchronously and the DEMOS2 application can't run without this application. A bash script
called 'start_celery_worker.sh' is provided to make starting a worker as easy as possible:

    ./start_celery_worker.sh

### Step 3: Running the NodeJS Server

The NodeJS server exposes a lot of cryptographic operations that the application depends on throughout. To run the
server, issue the following command line request from the Node/ folder:

    node index.js
