+ SSL Certificates
6 lectures 20:24

This lecture introduces many key topics such as:

  • Certificate Authorities (CAs)
  • SSL Certificate Validity Dates
  • Public Key Authentication
  • Private Key Authentication
  • Digital Signatures
Preview 03:33

This lecture introduces students to the three main types of SSL certificates. This includes:

  • Extended Validation Certificates (EV)
  • Organizational Validation Certificates (OV)
  • Domain Validation Certificates (DV)

We explain how each can be distinguished through a unique set of attributes.

Preview 03:58

This lecture explains how SSL certificates encrypt and decrypt data using mathematical hash values, and a public and private key pair. We also explore the digital signature, and it's important role in making sure a certificate is not fraudulent or altered. 

How SSL Certificates Work

This lecture explains in theory, how a certificate is obtained and verified through a Certificate Authority and our local system.

Obtaining a SSL Certificate

This lecture introduces students to Let's Encrypt. A free public authority that issues SSL certificates using Domain Validation. We explain the benefits of Let's Encrypt and some important information about this revolutionary new service.

Domain Name Server Administration

Students learn the signup process on the Digital Ocean website.

Introduction to Digital Ocean

We explore several server configurations offered by Digital Ocean. 

Droplet Configurations

Students learn to create a droplet (Virtual server) using the Digital Ocean admin panel. 

Creating a Droplet

Students learn to connect to their newly created Digital Ocean droplet using Terminal for MAC or PuTTY for Windows.

Install PuTTY/Terminal and Connect

Students learn to convert their Droplet into a web server using LAMP Stack (Linux, Apache, MySQL, PHP).

Students learn how they can further their knowledge in web development and become an expert in the field.

Become an Expert
  • Students will require an internet connection and PC or MAC Computer System.
  • Terminal for MAC or PuTTY for Windows

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.

Who this course is for:
  • No prerequisite knowledge required
  • Web developers looking to secure their websites using SSL
  • Students interested in learning about certificate authorities
  • Students interested in SSL Certificate Types for maximum security and credibility
  • Web developers who want to avoid costly fees and install a free, secure SSL Certificate using Let's Ecnrypt
  • Students interested in learning the basics of SSL Encryption
  • Web developers who want to direct all domain variations to HTTPS, instead of HTTP
  • Web developers who want to learn how to easily resolve the "Google Not Secure" warning label.
