Tor hidden services have an asymmetric key pair. That seems like it ought to do the job of authenticating the server and securing the connection to the client. When Tor clients reach out to normal servers, the final traffic passes through the exit node, so it makes sense to use application-level encryption there. But hidden service traffic stays entirely inside the Tor network, where encryption can be used the whole way, presumably. But occasionally, you see a
.onion using HTTPS.
What is the purpose of using HTTPS for darknet web sites? Does it provide any security benefits for the server or client, or is it completely pointless?
