Jake, Did not know if you ever got your answer. The short answer is YES. The answer is from z/OS Communications Server: IP Programmer's Guide and Reference found here: https://www.ibm.com/docs/en/zos/2.3.0?topic=reference-application-transparent-transport-layer-security-tls
I also have an assembler program that uses the EZASMI macro that sends a TCP alert to an Event Management application (IBM Netcool/OMNIbus) using AT-TLS. One of our issues was related to Mainframe security (e.g. ACF2 in our case). There is a CRYPTO class validation for resource CLEARKEY.SYSTOK-SESSION-ONLY that needs to allow access to all users for some SSL callable services. $KEY(CLEARKEY) TYPE(CRY) SYSTOK-SESSION-ONLY UID(*) SERVICE(READ) ALLOW Since we were calling this assembler EZASMI program from our Mainframe Automation product (OPS/MVS) this CRYPTO class needed to be added to the security ruleset. Hope this helps.
