vmware:vmhost_webserverssl

Description

The vmware:vmhost_webserverssl test is used to verify default self-signed certificates for ESXi communication are not used.

The vmhost_webserverssl_object element is used by a vmhost_webserverssl_test to define the name and connection string of the vmhost to be evaluated.

The vmhost_webserverssl_state element holds information regarding the default self-signed communication certificates of the specified vmhost.
