I want to add an SSL certificate to specific pages in wordpress. This is a pretty common thing to do if you want to add payment options to checkout pages on your site and you don’t want to add the SSL to the entire site.
Install WordPress HTTPS plugin
Select the page and check Secure Post.
Now grab a free SSL certificate to wordpress from somewhere like lets encrypt.
There is also a free godaddy one which I tried to apply for but they didn’t approve it – waste of time that one.
