Configure Unity App with Public Key

Note: The topics on this page are only applicable to Unity Apps that are integrated with the Appstore SDK.

To establish a secure communication channel between the Amazon Appstore and your app, you must configure your app with a public key. This public key is unique for every app. When you generate the public key from the Developer Console, Amazon generates a corresponding private key. These public and private keys form a key pair to sign license responses. Through this key pairing, you ensure that the users who install your app are authorized.

To configure your existing app with the public key:

Sign in to the Developer Console with your developer account.
From the navigation bar, choose My Apps. Find your app, expand the row, and then select View to open the app listing. If you don't already have an app, see Submit Your App to the Amazon Appstore.
Create a new version of your app. In the area below your app's name, click Add Upcoming Version.

Important: The link to the public key appears only when you create a new version or when you create a new app. If you had a new version in progress prior to the release of the Appstore SDK 3.0.2, you must complete your existing version and then create a new version. Only then does the public key link appear. (Alternatively, submit a Contact Us Case regarding your app and request that the Upcoming Version be cancelled.)
Go to the Upload Your App File screen.
In the Additional information section, click View public key.

Important: The public key is available when publishing a new version of an existing app or creating a new one.
In the Public Key dialog box that appears, click the AppstoreAuthenticationKey.pem link to download a PEM file. This file contains your public key.

PEM file download link
In the Assets folder of your project, create a new folder named as StreamingAssets.
Copy the AppstoreAuthenticationKey.pem file you downloaded, and paste it in your Assets/StreamingAssets folder.
