Introduction

Welcome to Driving License Use Case - Issuer application. In this application, you will experience how does a normal applicant would like to sign up for a verifiable credential and thereafter how a Issuer checks the information and issues a verifiable credential to the applicant.

You can either run this program in your local machine or try it out here: https://usecases.drivinglicense-issuer.vc-generator.com/

Initial Set Up

Generate API Key

Before you could use our API and SDK services, you would have to register to get the API keys.

1. Go to apikey.affinidi.com
2. Register for an account
3. Store the API Key and API Key Hash safely

Amazon SES

In our Issuer application, once the issuer has approved an application, the applicant will receive the credentials through their email. Hence, we will be using Amazon SES services.

1. Go to AWS Console https://console.aws.amazon.com/
2. Click on your username near the top right and select My Security Credentials
3. Under Access keys for CLI, SDK & API access, click Create access key
4. Store the Access key ID and Secret access key safely

Firebase

Note: This step will be optional.

In our issuer application, we will be using firebase to mimic issuer's database which stores all of the applications.

1. Go to Firebase Console https://console.firebase.google.com/
2. Create a new Firestore
3. Navigation to Project Settings
4. Look for firebaseConfig and copy the credentials. It should look like

  var firebaseConfig = {
    apiKey: <<SOME API KEY>>,
    authDomain: "<<SOMEP PROJECT NAME>>.firebaseapp.com",
    projectId: "<<SOMEP PROJECT NAME>>",
    storageBucket: "<<SOMEP PROJECT NAME>>.appspot.com",
    messagingSenderId: <<SOME STRING>>,
    appId: <<SOME STRING>>
  };

Configure .env file

1. Open terminal and navigate to the project folder
2. Run cp .env.example .env
3. Fill in the .env file with the details that you have gathered in the previous steps

REACT_APP_API_KEY=<<Afffinidi's API Key>>
REACT_APP_API_KEY_HASH=<<Affinidi's API Key Hash>>
REACT_APP_ENVIRONMENT=prod
REACT_APP_WALLET_URL=<<URL OF THE WALLET APPLICATION>>

REACT_APP_AWS_ACCESS_KEY_ID=<<AWS's Access Key ID>>
REACT_APP_AWS_SECRET_ACCESS_KEY=<<AWS's Secret access key>>

REACT_APP_FIREBASE_API_KEY=<<Firebase's apiKey>>
REACT_APP_FIREBASE_AUTHDOMAIN=<<Firebase's authDomain>>
REACT_APP_FIREBASE_PROJECT_ID=<<Firebase's projectId>>
REACT_APP_FIREBASE_STORAGEBUCKET=<<Firebase's storageBucket>>
REACT_APP_FIREBASE_MESSAGING_SENDER_ID=<<Firebase's messagingSenderId>>
REACT_APP_FIREBASE_APP_ID=<<Firebase's appId>>

How to run

1. Open terminal and navigate to the project folder
2. Run npm install
3. Run cp .env.example .env
4. Populate the credentials in .env
5. Run npm start
