VBA PROTECTION SOFTWARE? Or Other?

Short Story... I've been working on a macro that has caught my Parent Company's attention (all recent time).  Currently I am experiencing manipulation and scare tactics to hand my macro over. Of course it's password protected and clearly they want the password removed. Note: I am not too keen on bullying or handing over something I've been working on my own time. 

These people are smart enough, though,  to hack the password,if i did try to just hand over the .gms file.  But before Im forced to I want to make sure it's secured. But, I know my rights. Is there something out there (recommended) that can protect my macro? Make it completely unenviable? 

I did research - but it appears a lot of them are for excel.
