This repository contains the source code of VerificaC19, the Italian customization of the EU Digital COVID Certificate Verifier App for the Android Operating System. The repository is forked from the official EU Digital COVID Certificate Verifier App - Android
The DGC Verifier Apps are responsible for scanning and verifying DCCs using public keys from national backend servers. Offline verification is supported, if the latest public keys are present in the app's key store. Consequently, once up-to-date keys have been downloaded, the verification works without active internet connection. The Italian version adds some medical rules to the validation of the DCCs, defined by rules downloaded from national backend servers.
- For development, the latest version of Android Studio is required. The latest version can be downloaded from here.
- Android SDK version 26+
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 order to successfully build and run the project, you must have also downloaded the corresponding core repository from here. Both projects should be at the same folder level as eachother which would look something like
android-app
|___dgca-verifier-app-android
|___dgca-app-core-android
Modify app\build.gradle file, changing BASE_URL, SERVER_HOST and CERTIFICATE_SHA debug config values with release config values. Here you can find more info on app's endpoints.
This project uses the Gradle build system. To build this project, use the gradlew build command or use "Run" in Android Studio.
The following libraries are used in the project by the verifier app and the core app and are imported as Gradle dependencies:
- decoder. European core library that contains business logic to decode data from QR code payload and performs technical validations (i.e. correct signature verification, signature expiration verification, correct payload format etc).
- zxing. Library used QR code scanning.
- retrofit2. Library used for networking.
- gson. Library used by core module for JSON serialization/deserialization. All listed dependencies are already included in the official EU Digital COVID Certificate Verifier App for Android. No new dependencies have been included in the Italian customization of the app.
