How to make encrypted outgoing links via custom third party page?

Actually, I don,t know how to ask this question exactly.so, I'll explain it.

I've recently visited a site. when I click on its download link it's going to another page and displayed wait for 3 sec and displayed generate link button(top of the page). then I clicked on that button it scrolled down automatically the end of the same page with another button Get download link.

Now I get the download link. the question is How can I make my outgoing links like this. through another Page?

My site is on WordPress.

Kindly clear my doubt.
