Access the onion address in Tor Browser.
If it works, the tor portion is secure.

The httpd portion may be insecure, depending on how it is configured.

Does httpd:
* answer requests for its own config
* tell clients information about its own IP address
* look up addresses that clients send it in DNS

Sarah Jamie Lewis has done some excellent work on fingerprinting onion
services - there are probably a few more major vectors I've forgotten.

Certificates are irrelevant for most use cases: the traffic is end-to-end
encrypted and authenticated to the address by the onion service protocol.

Certificates are only useful to modify browser behaviour, or authenticate
your service as belonging to a CA-certified DNS domain / organisation.
