 ## Introduction
-**hapi-auth-keycloak** is a plugin for [hapi.js](hapijs) which enables to protect your endpoints in a smart but professional manner using [Keycloak](keycloak) as authentication service. It is inspired by the related [express.js middleware](keycloak-node). The plugin validates the passed [`Bearer` token](bearer) online with help of the [Keycloak](keycloak) server and optionally caches successfully validated tokens and the related user data using [`catbox`](catbox). The caching enables a fast processing although the user data don't get changed until the token expires. It plays well with the [hapi.js](hapijs)-integrated [authentication feature](hapi-route-options). Besides the authentication strategy it is possible to validate tokens by yourself, e.g. to authenticate incoming websocket or queue messages.
