From Keycloak's Website:

Keycloak is an integrated SSO and IDM for browser apps and RESTful web services, built on top of OAuth 2.0, OpenID Connect, JSON Web Tokens (JWT) and SAML 2.0 specifications. Keycloak has tight integration with a variety of platforms and has an HTTP security proxy service where we don't have tight integration.

This project is an unofficial Keycloak connector for C#. It is designed as an OWIN authentication middleware component, and can import user data, including roles and authorization information, into the OWIN pipeline for use in ASP.NET, WPF, and any other C# application.

All relevant documentation to Owin.Security.Keycloak and KeycloakIdentityModel can be found on the GitHub Wiki Page.
