Introduction

This document describes implementation of sunbird rc qr code generation based on the wiki.

SB-29126 - Getting issue details... STATUS

Problem Statement

To support the backward compatibility for qr code generation.

Prerequisite

Add the below data in /sunbird-rc-core/services/certificate-api/configs/keys.js

const qrType = process.env.QR_TYPE || 'W3C-VC'; 
const certDomainUrl = process.env.CERTIFICATE_DOMAIN_URL || "https://dev.sunbirded.org";

We are supporting 2 types of qr code.

  1. W3C-VC (old)

  2. URL-W3C-VC (new)

according to the formate what you need, change the process.env.QR_TYPE variable;

change the signingKeyType to KeyType.RSA in /sunbird-rc-core/services/certificate-signer/configs/keys.js

const signingKeyType = process.env.SIGNING_KEY_TYPE || KeyType.RSA;

Solution

To make the Sunbird RC QR codes compatible with the existing version of Sunbird consumption app, the QR code generated by Sunbird RC should also be a URL. The proposed solution is to enable a provision in Sunbird RC to generate the QR code in URL format along with the W3C-VC data.
