How do I digitally sign my macros?

[John]

I've created a project tracking workbook for my boss who is minimally
computer literate. I've included several macros to aid in data entry and
display.

Is there any way I can digitally sign these macros or this spreadsheets so
that the boss can use these spreadsheets without having to enable all macros
and expose himself to malicious code in other spreadsheets?

I appreciate your help, -John
