### Testing the application
The project comes with a test mobile application and a test web application that can be used to try the MobileAuthApp authentication feature even if you don't have any web applications or mobile applications that require user authentication. Both projects come with a README file that help with a setup.

# TestMobileApp overview
### The purpose
The TestMobileApp was created in order to demonstrate how a different application on the Android smartphone could use the MobileAuthApp for user authentication purposes.
### Installing the application
The application installation process is the same as with the MobileAuthApp. Check the guide in the project's [main readme file](https://github.com/TanelOrumaa/Estonian-ID-card-mobile-authenticator-POC#installing-the-application-on-the-phone).
### Using the application
In order to use this application a backend server must be running that can issue challenges and verify the token created by the MobileAuthApp.
Use demoBackend application that is included in the project. Follow the demoBackend setup guide and once you have a backend running take the https address of the backend
and add it in the TestMobileApp's MainActivty.kt file as the new value for the constant variable BASE_URL (this is easly noticeable in the class as it is pointed out with a comment).
Now the app can be used.

# Demo backend + website for mobile authentication project.
## How to run.
### 1. Clone GIT repository
### 2. Setup HTTPS
Since Web eID only works over HTTPS connection, you'll need to serve the backend and website with an HTTPS certificate. A suitable tool for that is ngrok (https://ngrok.com/).
To use ngrok, download it and then run the command (may need administrator rights)
```ngrok http 8080```
and you should see something like this:
```

Copy the second forwarding link (the one with https) and put it in ```com.tarkvaratehnika.demobackend.config.ApplicationConfiguration.kt``` as ```val WEBSITE_ORIGIN_URL = "https://yourlinkhere.com"```
### 3. Run the project
Use your favourite IDE or just run it via commandline with ```./mvnw spring-boot:run```
On your Android device browser navigate to the url you copied earlier and you should see the website landing page. If you have the mobile authentication app installed, you should be able to log into the website with your Estonian ID-card.
