Overview

This library can be used to realize use cases for interacting with a German Health Card (eGk, elektronische Gesundheitskarte) via a mobile device.

Typically you would use this library as the high level API gateway for your mobile application to send predefined command chains to the Health Card and interpret the responses.

For more info, please find the low level project HealthCardAccessKit and a Demo App on GitHub.

See the Gematik GitHub IO page for a more general overview.

Getting Started

HealthCardControlKit requires Swift 5.1.

Setup for integration

Carthage: Put this in your Cartfile:

github "gematik/ref-HealthCardControlKit" ~> 1.0

Setup for development

You will need Bundler, XcodeGen and fastlane to conveniently use the established development environment.

Update ruby gems necessary for build commands
```
$ bundle install --path vendor/gems
```
Checkout (and build) dependencies and generate the xcodeproject
```
$ bundle exec fastlane setup
```

Build the project

$ bundle exec fastlane build_all [build_mac, build_ios]

Code Samples

Take the necessary preparatory steps for signing a challenge on the Health Card, then sign it.

let challenge = Data([0x0, 0x1, 0x2, 0x3, 0x4, 0x5, 0x6, 0x7, 0x8])
let format2Pin = try Format2Pin(pincode: "123456")
CardSimulationTerminalTestCase.healthCard
        .verify(pin: format2Pin, type: EgkFileSystem.Pin.mrpinHome)
        .flatMap { _ in
            CardSimulationTerminalTestCase.healthCard.sign(challenge: challenge)
        }
        .run(on: Executor.trampoline)

Encapsulate the PACE protocol steps for establishing a secure channel with the Health Card and expose only a simple API call .

try KeyAgreement.Algorithm.idPaceEcdhGmAesCbcCmac128.negotiateSessionKey(
                channel: CardSimulationTerminalTestCase.healthCard.currentCardChannel,
                can: can,
                writeTimeout: 0,
                readTimeout: 10)
        .run(on: Executor.trampoline)

See the integration tests Tests/HealthCardControlTests/Integration for more already implemented use cases.
