In the previous tutorial, we learned the best practices to set up a global.xml file and externalize the properties in Anypoint Studio. In this tutorial, we are going to learn how to create secure properties files. These properties files are where you will want to insert information such as private keys, client enforcement tokens, or other bits of information that you will want to reuse in multiple places in your project. When your Mule flows start to become long and robust, having all of your variables in a properties file will allow you to only change values in one place without having to modify every instance of that value throughout your project.
