33// hostname for the current page with any leading "www." removed, though for
34// special built-in pages (e.g. chrome://settings), it can be a descriptive
35// string.  The EV cert name is the organization name of the EV cert holder and
36// is only present when the current page's security status is EV_SECURE.
