Need an SSL/TLS-enabled Socket Gateway

I've been using a slightly modified version of the SocketGateway (examples.socket.SocketGateway) for over 15 years (modified just to comment out the "welcome" message) with great success.  Our legacy ERP system has several processes that communication on TCP/IP sockets and we've been able to streamline multiple integrations by letting it talk to my ColdFusion sockets and using CF code to connect to partner APIs.

The new version of the ERP system has changed one of those socket processes to communicate over TLS and my CF socket can no longer understand what it's sending.  Strangely, the process still CONNECTS, but what I would typically receive as a single "message" with an EOF character is now broken up into multiple messages and gets logged as gibberish (the usual sort of binary characters you see from encrypted data).  I'm trying to figure out what changes would be needed to allow this connection to work properly.  I've started down the road of trying to modify the SocketGateway.java file to use javax.net.ssl and create an SSL socket, but I'm barely competent in Java and the few examples I found don't seem to be doing the trick.

It's a longshot, but has anyone else out there worked much with the SocketGateway functionality in CF over the last 10 years and run into this?  To be clear, I'm NOT talking about WebSockets (which is mostly what comes up when I try to research this).  Thanks in advance.
