Max Kahan of IBM has published a hands-on blog posting on how to configure an IBM MQ application for mutual TLS authentication.
https://developer.ibm.com/tutorials/configuring-mutual-tls-authentication-java-messaging-app/
In this tutorial, we’ll show you how to secure the queue manager and a client application, enabling them to complete a two-way TLS handshake and secure a messaging channel. Although we’re using a Java example, the steps apply to securing applications more generally with MQ.
