Hi..what is it you'd like to check? I don't understand the question. Are you asking if this is a new feature?? (as outlined in the documentation, it is) or are you asking how to use it? For making use of this in any real sense, you would have to own your own CA to sign a certificate issued by Webadmin, or upload a certificate you have crafted specifically for this purpose (as is used by businesses with the appropriate resources, or if you have such capabilities)
