Firstly, yes I searched for my question/answer and found nothing useful.
I'm working with... an "interesting" client to say the least. PDF prints of my schedule are not sufficient, and they require the .xer file that I am working with. I absolutely DO NOT want them to be able to modify any of the content without prior written consent (this has been an ongoing issue - can you tell??)
How do I password protect an exported .xer file so that whoever opens it on their machine cannot modify it in any way?
