The image below is a block diagram of e-Signet comprising various components along with the different layers and external systems.
The relying party system is any application who would need the verified user information and a unique user login functionality to provide various services online. It depends on
OpenID Connectlibraries to integrate with e-Signet.
The key bound credentials stored in the wallet app can be used to verify the user to avail the services provided by a Relying party system.
- This is the front-end application which is mainly responsible for the user interactions.
- Runs on the end user browser and invokes the REST API endpoints of the e-Signet Service component.
- On completion of all user interactions, it redirects to the relying party's web application with relevant details.
- It is built using the
- e-Signet service is the main backend application which has various layers and integrates with multiple components.
- It has a Service layer containing the business logic to serve the below API endpoints:
OpenID Connect APIendpoints for the relying party consumption
- REST API endpoints for UI component consumption
- REST API endpoints for OIDC client management
- The Service layer is also dependent on Cache layer, Data layer, Key Manager, Authentication Wrapper and esignet Core components.
- The e-Signet service also has a Cache layer which is responsible for:
- Temporarily maintaining the current transaction details with a short expiry time
- Providing faster access and update of transaction details
- It relies on Spring cache to integrate with a distributed cache. Currently,
Redisis configured to ensure data sharing across multiple instances of esignet service.
- The Data layer is used to store the relying party client or application details.
Postgresis used as the current database.
- This is built using the
- These library components acts like a proxy to the Authentication system.
- Expected as runtime dependency to facilitate the use of officially released container images even in custom integrations.
- Key Manager is used for secure key management and cryptography functionalities required by the e-Signet service component.
- It can be integrated with a HSM (Hardware Security Module) for the secure storage of keys.
- Typically, Key Manager is run as a service, but it is used as a library in the e-Signet Service to minimize the effort of managing extra containers.
- It depends upon the Data layer for maintaining the metadata on keys.
- e-Signet core is a library component used to maintain the common interfaces, DTOs and utility methods.
- Used as a build-time dependency for e-Signet service.
- This system could be any functional or foundational ID system that contains the resident demographic and biometric information (optional).
- It facilitates the mechanism to perform identity verification and share the required user information.
