Integrate with MOSIP e-Signet

Description

This guide provides steps to integrate OpenG2P with e-Signet with MOSIP as the authentication provider.

Pre-requisites

1. MOSIP IDA is installed

2. The e-Signet server is installed and configured to connect to MOSIP IDA

3. MOSIP IDA APIs are accessible from the machine running the e-Signet server

4. Both Yes/No and KYC APIs are enabled on MOSIP IDA

5. e-Signet APIs are accessible from machines running OpenG2P

6. Biometric auth devices (already onboarded on MOSIP) are available for authentication

7. Email and SMS are enabled on MOSIP IDA for OTP authentication

8. MOSIP Partner Management Services (PMS) Portal or APIs must be accessible to both MOSIP Partner Admin and OpenG2P Admin

9. MOSIP Partner Specific User Token (PSUT) ID type is configured. See Configure ID Types.

Steps

Configure OpenG2P as a partner on MOSIP

1. Create an Auth Partner for OpenG2P on MOSIP.

   • Guide for MOSIP 1.2.0

   • Guide for MOSIP 1.1.5 (TBD)

2. Create a MISP Partner for OpenG2P on MOSIP.

3. Note down the following from the above steps:

   1. Auth Partner ID

   2. Auth Policy ID

   3. Auth API Key

   4. MISP License Key

   5. Auth partner signed certificate

   6. IDA Partner certificate (App id: IDA, Ref Id: PARTNER)

Configure OpenG2P as relying party on e-Signet

Using PMS API

This method is applicable if MOSIP Partner Management APIs are available. These steps are executed by MOSIP Partner Admin

1. Create an e-Signet OIDC client using PMS OIDC API:

• authParnterId: Partner ID in this step.

• policyId : Policy ID in this step.

• publicKey: Generate JWK.

• logoUri: URL of your logo accessible publicly.

• grantTypes = ["authorization_code"]

• clientAuthMethods= ["private_key_jwt"]

• redirectUris: URLs of the form https://<your web portal>/auth_oauth/signin

Note down the Client ID as an output of the above step.

Using e-Signet API

This method is applicable if MOSIP Partner Management APIs are not available.

1. Create an e-Signet OIDC client using the following API:

• clientId: Arbitrary string.

• clientName: Arbitrary string.

• relyingParnterId: Partner ID in this step.

• publicKey: Generated JWK.
