[Quickfixj-users] SSL handshake callback and socket handle access

[Aaron B. <aar...@gm...>]

Hello,

I've been digging through the source code for acceptors to figure out how
to get a handle to the underlying socket as connections are established. I
have two things I would like to do with that handle. In my case I am using
SSL with client certificate authentication. All of that is working properly
with the basic configuration options.

1) Add a handshake completed listener. The basic structure looks like

((SSLSocket) socket).addHandshakeCompletedListener(handshakeCompletedEvent
-> {
            try {
                X509Certificate cert =
(X509Certificate)handshakeCompletedEvent.getPeerCertificates()[0];
                System.out.println(cert.getSubjectDN().getName());
            } catch (SSLPeerUnverifiedException e) {
                e.printStackTrace();
            }
        });

Ultimately there are some things I would like to extract from the client
certificate in order to authorize a connection and potentially kill it once
the certificate is available.

2) Extract a handle to the connection so it can be terminated. There may be
a reason to disable connections belonging to a session and I would like to
be able to wire up a mechanism to do that through the broader management
components of the platform.
