I’m currently working on a project where I need to manage file sensitivity using encryption and decryption with Microsoft Information Protection (MIP). While going through the Microsoft documentation, I’ve come across a few points that need clarification.

Specifically, I’d like to understand the relationship between Microsoft Purview Information Protection (MPIP) and the Microsoft Information Protection SDK. For instance, if a developer sets up labels and policies for data protection on Microsoft Purview or Microsoft Compliance Center, can these policies and labels be applied to files at upload time using the MIP SDK? Or are MPIP and MIP SDK unrelated in this context?

Additionally, I’m seeking guidance on how to use the Policy SDK in C#. I’ve only found documentation for File SDK and Protection SDK in the Quickstarts document. Is this question related to the first question, or is it addressed in the Policy SDK Handler(C++) ?

Any insights would be greatly appreciated!

Thank you.

I haven’t done anything else besides searching for documentation.
