How to add version after run Gulp in Laravel?

I use gulp in laravel.

I need create and check version after run galp.

For example:

befor: main.css

after run gulp: main.min.css?v=C0LpH0IdGXVeCRXA27r1ky5Ikj0Tj3u7MXtfTQQgFl81

My code:

gulp.task('CssConverter', function () {
 gulp.src(['public/site/css/*.css', '!public/site/css/*min.css'])
    .pipe(foreach(function(stream, file){
        return stream
            .pipe(cssmin())
            .pipe(rename({suffix: '.min'}))
    }))
    .pipe(gulp.dest('public/site/dist/css'));
});

how to use version in gulp?
