[keycloak-dev] Scripts to generate X.509 certificates

Ahoy, I'm adding X509 authentication tests for *Key Usage* and *Extended Key Usage*. Now I got stuck looking for the scripts that generate these files https://github.com/keycloak/keycloak/tree/b2f10359c8c33dd0a843c3ee28e0c8e.... Do we have them? The reason why I'm asking, is because I need to flag *Extended Key Usage* as critical for testing purposes. Also, I couldn't find the CA key, to sign another client certificate. Of course is possible to recreate everything from scratch, but that would take a considerable time making sure that everything is in the right place.
