SSL in a z/OS TCP/IP server program.

I have a TCP/IP server application running in a z/OS region, processing HTTP requests. Everything works fine except now I want to add extre security to it by adding SSL support. Can this be done without using USS? Can SSL support be accomplished in a z/OS region? I am currently using the EZASMI API macros.

Is your program actually handling the http traffic or do you have something else, like IBM's HTTP server, CICS, or WebSphere?

If you are actually handling the http traffic, you can do SSL.  However I am 99% SSL requires Unix System Services.

However, since you have an IP based application you might be able to use AT-TLS, Application Transparent Transport Layer Security.  This will allow you to use TLS without your application having to know anything about it.

Yes, I am handling the http traffic. I was 90% sure that SSL required USS but was hoping there was another way of doing it. Oh well.
But AT-TLS sounds very interesting and perhaps exactly what I was looking for.
Thank you very much for your response, it helped me a lot.
