Ready API Tool - Sensitive Information inside ready API xml file

Hi Team,

I have one query for my requirement and wanted to check with technical team.

Problem Statement: I'm using licensed ReadyAPI tool currently.

I'm using ready api project xml as part of my framework to trigger my API configured test cases in inside tool. That project xml gets stored my API subscription key inside xml and I want to mask or hide those sensitive information in file so that it is not misused.

Is their any way to achieve that we can do inside project xml file that is visible like encrypted but still it should work fine whenever I run by xml file.

Thanks,
