Golang windows registry package creation.

Due to unexpected events I am behind on a project for a client. I would like to outsource the creation of a package to another freelancer. Requirements are as follows: - Package should be written in golang - Package should have four functions callable from other go code (public) - First function should return an array of all of the windows registry keys and their currently assigned values. - Second function should save these values to a .json file for later use. - Third function should recall this data from a json file for use - Fourth function should compare two files and return a list of differences between the two snapshots for analysis of changes to the windows registry. - It should work on windows 10 and 11.
