SSL Certificates

To understand what DigiCert does, you first need a good understanding of what SSL certificates are, why they’re important, and how you obtain one. 

What Is An SSL Certificate? 

An SSL certificate is a small piece of code that allows your web browser to communicate securely with your website. When you visit a site using HTTPS, you’ll see a lock icon next to the URL address bar.

This indicates that the site uses encryption technology to protect your data as it travels between your computer and the server.

Why Do I Need One? 

The main reason you’d want an SSL certificate is that it encrypts your connection with the server. Without this protection, anyone who intercepts your network traffic could read your sensitive information.

For example, if you were shopping online and entered credit card details, someone else would have access to those details without your knowledge.

Specifically, SSL allows sensitive information (including card numbers, social security numbers, login details) to be transmitted securely.

Generally, the data that is sent between browsers and web servers is sent and received in plain text. This leaves the user vulnerable to a cyber attack. SSL prevents this. 

A website needs to be secure to protect users’ personal information. An SSL certificate is one of the most important components of an online business.

They help to create a trustworthy environment so that potential customers feel safe and confident in making purchases on your site. 

How Does An SSL Certificate Make A Connection Secure? 

A browser connects to a secure website over SSL. The browser and the server exchange information about each other, including the public and private keys.

This information is then used to encrypt the data being transferred between them.

How Can I Obtain An SSL Certificate? 

To receive an SSL certificate, you must first create a Certificate Signing Request on your server. In turn, this creates both a private and a public key on your server.

The Certificate Authority (DigiCert) uses the Certificate Signing Request data file to create a data structure that matches the private key, without actually compromising or seeing the private key itself. 


SSL is the older protocol while TLS is the newer one. However, because SSL is a more commonly used term, DigiCert uses them interchangeably when describing certificates or how the transmitted data is secured.

As such, when you purchase an SSL Certificate from DigiCert, you are actually receiving a TLS certificate.

For example:

Primary Domain: www.example.com

Subject Alternative Names (SANs): mail.example.com, blog.example.com, it.example.com, portal.example.com, hr.example.com, login.example.com, shop.example.com.
