lock / protect excel macros

I am having an excel file which contains certain macros.

I have locked / password protected vba project for viewing.

This file will be used by certain users.

I want to restrict circulation of this file.

I want that only those users whom i permit / authorize should use this file and I want to restrict unauthorized copy and use of this file.

Is there any way similar to licence / product key whereby user has to contact me before they can use the excel file.
