Embedding of an authenticator

Android

Embeddable ASM libraries and dependencies will be delivered by an authenticator vendor as AAR libraries packaged in Maven repositories for Android Studio. The instructions below explain how to embed FIDO ASMs into your mobile application.

Embedding an Authenticator—Required Descriptors and Libraries lists the descriptor class name and ASM library name you must provide when you embed Presence, PIN, Password, and Native Biometric Authentication.

Add a descriptor

To add a descriptor, create a file named asmdescriptors.json and place it in a res/raw subfolder.

For example, here is what the file would look like to embed the PIN-, Native Biometric-, and Yes/No-based modules:

{
    "descriptorclass":[
     "com.vasco.fido.uaf.asm.presence.PresenceASMDescriptor",
     "com.vasco.fido.uaf.asm.userinput.PinASMDescriptor",
     "com.vasco.fido.uaf.asm.biometric.NativeBiometricAuthenticationASMDescriptor"
  ]
}

Add activities to your manifest

Android Studio automatically merges the activities from the various AndroidManifest.xml files within library projects. All activities should therefore be declared only within individual library projects.

Add an authenticator

The steps below outline an example of how to integrate the Presence ASM.

You may see errors regarding Swift symbols when using the ASM provided by OneSpan with the Objective-C version of NokNok_app_tutorial_plus_iOS app from Nok Nok package v7.0.2. To correct the issue, add an empty Swift file to the project and when Xcode offers to create a bridging header, choose YES.

To integrate the Presence ASM with C++

1. Include the corresponding header file:

   #import <FIDOUAFPresenceASM/FIDOPresenceASMInstanceCreator.hpp>

2. Open the AppDelegate.m file and add the following code in: (UIApplication *)application didFinishLaunchingWithOptions method to embed an authenticator:

   asmcore::ASMFactory::addAuthenticator
   (FIDOPresenceASMInstanceCreator::createInstance());

To integrate the Presence ASM with Swift/Objective-C

1. Include the corresponding header file:

   import FIDOUAFPresenceASM

2. Open the AppDelegate.swift file and add the following code in application:didFinishLaunchingWithOptions method to embed an authenticator:

   // Add presence authenticator to ASM
   FIDOPresenceASM.registerPresenceAuthenticator()
