Hi all ! Today, we’ll see how to change our http server to an https one without paying one fucking cent thanks to let’s encrypt which is now officially in public beta. We will create our certificate and use them with nginx ! Why HTTPS ? First of all, we could ask why HTTPS ? That will change anything for users ? Hmm, good question. I heard a rumor that http website are not as well indexed in Google (bullshit) , a rumor seems to say that firefox is going to blacklist all website without HTTPS, etc… Let them talk and let focus on what matters, understanding how it works.
