Each certificate, configuration and file appears once, with the listeners that carried it.

The names above are what the certificate asserts, signed by the issuer it names, which may be a public certificate authority, a private one, or one a builder ships. This site verifies none of it, so treat a name here as a lead to investigate, never an attribution.
