In the modern internet age, delivering web content over a secure protocol has become essential. 

Since January 2017, Google attaches a warning label to any website that does not secure sensitive web page content by delivering it using HTTPS. This includes web pages that contain forms asking for usernames, passwords, credit cards and other sensitive information. 

In the near future Google plans to roll out a requirement for all web pages to be secured. Warning labels will become progressively more aggressive, and eventually highlighted in red, bold colors on the address bar. 

It is easy to see the consequences of not complying with this new requirement. You invest time, money and energy to drive traffic to your website. Your users expect a secure browsing experience and will likely be deterred from using your page when they see such warning labels attached. 

There is a common misconception that securing a webpage over HTTPS requires expert server knowledge and is a costly and cumbersome process. 

The purpose of this course is designed to teach you everything you need to know about HTTPS and SSL certificates. We start with the basics. Exploring the theory and definitions that will be useful in developing your understanding. 

From there, we dive into configuring a server on Digital Ocean and installing a free SSL certificate known as Let's Encrypt. We also explore setting up Cron Jobs on an Ubuntu server, to automatically renew your certificate periodically. 

After completing this course, you will easily be able to secure any web page using HTTPS and free SSL certificates.

This is one of the best IT related courses I've ever taken. The teacher was simple, clear, and straight to the point. Very practical.

Less than 15 minutes of the course is actually "How to install a free certificate with Let's Encrypt", but it was still interesting to have a refresher of SSL and to learn about using DigitalOcean.

Plenty of background info and detailed content. Needed to play at 1.25 speed as it played back a little slow. Good course

Le cours est bien pour les personnes qui font du développement web, le son est clair, les étapes sont bien définies. mais ce n'était pas ce que je chercher. ce n'est pas un cours très avancé sur la partie ssl

I Was Happy After Learning This Course, Because I am A New Developer And I Dont Know How To Secure Websites Using SSL .

So far ... only been through section 1. It's mostly all text narration of slides. A few examples and diagrams of the certificate download & validation (like UML sequence diagrams) would have helped understand the process better. But I'm continuing further in this course and depending on how it goes, will revise my rating accordingly.

The narrator clearly enunciated words and was easy to understand. He has a VERY pleasant voice. There could be better diagrams with theory behind how each aspect works. The narrator pronounced cache as cash-ay instead of like cash. He also pronounced Apache as Apash-ay rather than Apach-ee. He pronounces ch as soft sh instead of as hard ch (like chalk). He may have a Canadian dialect? Overall, I really appreciated this course and thought highly of it. If you feel this feedback harms your ability to sell this great tutorial, I will remove it upon request.

Buena. Aclaró muchos conceptos. Se podría mejorar el subtitulado,q que tienen errores y confunde un poco.

This course is perfect and I loved it. Just need a very tiny update over one command while it calls a package from Let's Encrypt. Here is how I could get it working since my Ubuntu refused the repo typed in the video: https://certbot.eff.org/lets-encrypt/ubuntubionic-apache

Nilesh4 October 2019

Good course for setting up Let's Encrypt SSL Certificate on a virtual host server. Had other methods like installing it on shared servers were also discussed it would have been great

Curso básico de como configurar un servidor apache con HTTPS y como generar y renovar certificados SSL con Lets Encrypt

Israel1 February 2019

I don't know exactly why do I need to use DIgitalOcean, what role does they play in order to obtain certificate. Will be nice if explain the data flow of the SSL certificate works in real life. How does I can obtain the .key and .crt for web pages? How many time do I need to pay DigitalOcean services, once I install SSL in web page? There is no another way to do it without payment (DigitalOcean services)? Thank you

Yves28 September 2018
