+# This file contains an example configuration of the nginx HTTP server.

+# HTTPS for Kea to provide secure comunication and client side
+# certificate verification to allow only authorized clients to
+# access the Kea RESTful API.

+# Client certificate and key:
+# openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout \

+# Then start the HTTPS server:
+# nginx -c /path/to/kea-nginx.conf start
