PoC for securing AspNetCore based Web Apps with Keycloak.

PoC for ASP.Net Core Keycloak Integration

Simple example for securing an AspNetCore Web App with Keycloak.

The example consists of two modules:

• WebApi - A simple stateless REST Web-Service that is secured with JWT authentication.
• WebApp - A simple Web App that is secured via Keycloak.

The WebApp module demonstrates a basic integration with Keycloak by leveraging the built-in OpenID Connect support in AspNetCore which is additionally augmented with Keycloak specific configuration, like client role extraction. Further more, the WebApp calls the WebApi with an Access-Token provided after a successful authentication, to demonstrate calls to backend services.

The following features are currently supported:

• Single-Sign in with Keycloak
• Logout with Keycloak
• Access client specific role information (resource_access claim)
• Automatic Access-Token refresh in background
• Extract Access-Token to call backend-services.
