+short_description: Local keys and certificates in Fortinet's FortiOS and FortiGate.
+description:
+    - This module is able to configure a FortiGate or FortiOS (FOS) device by allowing the
+      user to set and modify vpn_certificate feature and local category.
+      Examples include all parameters and values need to be adjusted to datasources before usage.
+      Tested with FOS v6.0.5
+version_added: "2.9"
