protocol, enabled-algorithms and random-number-generator may be extracted and consolidated but not hostname-verification and require-mutual-authentication.

I think that's what you mentioned but wanted to disambiguate it. :-)

Well, I would like to also consolidate hostname-verification and require-mutual-authentication, but perhaps that's not feasible and indeed we won't. Let's see how far we can take this ;).

If the certificate you used (akka-remote/src/test/resources/ssl/pem/certificate.pem ) it the one that I think then I think the problem is that's a self-signed certificate.

In akka#29061 I had some handshake errors (bad_certificate or can't verify signature) when using the PEMs and certificates from akka-pki/test/resources. In akka@e5897b2 I added a handful of certs, and scripts to create them, that will pass the handshake and fix this PR.
