About

This repository contains the source code of the EU Digital COVID Certificate Validation Decorator.

The Validation Decorator is an interface between the validation service and an internal backend system (demo) for the exchange of digital covid certificate information.

The validation has complex work flow that involves

• dgca-validation-service - additional service on travel system
• dgca-booking-demo - travel system mock
• dgca-booking-demo-frontend
• dgca-verifier-app-android - provide dcc
• dgca-booking-demo-backend

Development

Prerequisites

• Open JDK 11
• Maven
• Docker
• Authenticate to Github Packages

Authenticating in to GitHub Packages

As some of the required libraries (and/or versions are pinned/available only from GitHub Packages) You need to authenticate to GitHub Packages The following steps need to be followed

• Create PAT with scopes:
  • read:packages for downloading packages

GitHub Maven

• Copy/Augment ~/.m2/settings.xml with the contents of settings.xml present in this repository
  • Replace ${app.packages.username} with your github username
  • Replace ${app.packages.password} with the generated PAT

GitHub Docker Registry

• Run docker login docker.pkg.github.com/eu-digital-green-certificates before running further docker commands.
  • Use your GitHub username as username
  • Use the generated PAT as password

Build

Whether you cloned or downloaded the 'zipped' sources you will either find the sources in the chosen checkout-directory or get a zip file with the source code, which you can expand to a folder of your choice.

In either case open a terminal pointing to the directory you put the sources in. The local build process is described afterwards depending on the way you choose.

Build with maven

• Check settings.xml in root folder and copy the servers to your own ~/.m2/settings.xml to connect the GitHub repositories we use in our code. Provide your GitHub username and access token (see GitHub Help) under the variables suggested.
• Run mvn clean package from the project root folder

Run with docker

• Perform maven build as described above
• Run docker-compose up from the project root folder

After all containers have started you will be able to reach the application on your local machine under port 8080.

Documentation

The Validation Decorator is a template. To make your own adjustments, the three interfaces KeyProvider, BackendRepository and AccessTokenPayloadBuilder should be implemented.

KeyProvider provides the necessary keys and certificates. Separate keys for JWT, certificates for Validation Service and others are provided.

BackendRepository provides the interface to the internal service. In this example dgca-booking-demo-backend is connected and should demonstrate an airline.

AccessTokenPayloadBuilder basically serves as a converter to create the AccessTokenPayload from the given data.
