What SSL Encryption is and how it Works in WooCommerce

Today, over 22 percent of the world’s e-commerce industry is powered by WooCommerce.

Unfortunately, the simplicity and extensibility nature of this engine come at a cost: it’s a favorite target of hackers, and owners of WordPress websites frequently experience cyber-attacks like malware and DDoS.

Comprehending it, now the WooCommerce store security has become a burning issue for website owners and developers. It’s easy to find a host of staunch advice on this platform, but usually, the easiest ideas are the most prudent.

It’s been tested that the best security tip for WooCommerce is to install SSL certificates. Some business owners think that the installation of SSL certificates should be done by developers.

If you are one of them, then this article will serve you well. You’ll learn what SSL encryption is, and how it works in WooCommerce.

What’s SSL?


Secure Socket Layer, popularly known as SSL is a security protocol layer occurring between a browser and an internet server purposely installed to encrypt, secure, and privatize the communication between the two endpoints.

SSL is a technology meant to make it hard for anyone who has no right to access information being gathered, processed, or transmitted over the internet.

The SSL technology applies key pairs for authentication: a public key accessible to anyone and a private and confidential one.

Basically, what happens is that the store (business) owner possesses the private key and has the sole authority to encrypt information being transmitted with a public key.

Also, it implies that anyone can confirm the security status of the site using the public key. But this does not necessarily imply that they are “physical” keys stored by the business owner.

 Instead, they are integral in the SSL certificates installed on the site.

Now, check the site you’re currently browsing on your computer and keenly observe the address. Does it start with http:// or it is https://, and a green padlock at the beginning?

 If it starts with http:// then the website has no SSL certificate installed on it and doesn’t have the right online security. If it starts with https://, and a green padlock, it implies that the site has an SSL certificate installed on it hence it’s secure.

SSL certificate is a fundamental factor in receiving the top ranking on Google Search Engine Results Pages (SERPs). As a matter of fact, Google shows vivid favoritism for WooCommerce stores that embrace the SSL certificate.

This clearly signals that security is paramount in the e-commerce industry and Google isn’t taking SSL certification lightly. To drive this point home, from October 2017, Google Chrome began labeling those sites without SSL certification as “Not Secure”.

This implies that any internet user who visits your WooCommerce site that is marked “Not Secure” will leave immediately: nobody wants to lose their money anyway.

What’s the Importance of an SSL Certificate?

Internet users not only value their privacy but also their security online. If your eCommerce store isn’t SSL certificate enabled, then you’re certainly going to lose customers.

Many benefits come with SSL certificate accredited eCommerce stores such as:

  • Store owners can easily encrypt customer information like credit card numbers and payment data thus barring hackers from stealing it.
  • Users can easily confirm whether their businesses (store owners’) are registered and that they are the rightful owners of the domain
  • Visitors and potential customers will more likely trust and make purchases from SSL certificate-enabled sites.

Today, according to Builtwith, out of a possible million eCommerce platforms, WooCommerce has the largest number of subscribers and this contributes to its popularity.

By joining the internet community, store owners can easily find an audience far by adopting advertising media like Google Adsense or even Facebook Advertisement.

This is a signal that physical advertisement of the product is slowly becoming obsolete.

Due to the rapid growth of online stores, money transfer between the customers and sellers is as well moving from being physical to digital with a couple of options in the market such as the use of credit cards, PayPal, Skrill, online banking, bitcoins, et al.

SSL certificates aren’t just crucial for WooCommerce: they help protect all websites. Also, SSL has SEO advantages as they are highly ranked by Google.

All sites running any sort of eCommerce business, WooCommerce included, the SSL certificate is exceptionally essential as they often involve the collection, process, and transmission of Personally Identifiable Information (PII).

Even if users are required to make a payment outside the site via payment gateways, the site will still collect information like email addresses and delivery addresses.

Enabling your WooCommerce store with an SSL certificate will add security and minimize the access of the data by unwanted users.

Communications over the conventional “http” are transmitted in “plain text” implying that hackers or any dishonest person can read them – who manages to intrude on the communication between internet users and websites.

Supposing it’s an order, a cart, or any sort of form with login details, the hacker easily gains access to that information as it’s legible.

This is an issue with new eCommerce store owners as they might not be aware of the security of their stores. The majority don’t understand security credentials and how to protect their businesses.

Adding SSL certificates to traditional http connection creates an additional security layer: the connection between the user and the website is encrypted.

In case an intruder manages to infiltrate the connection, the extra encryption layer denies them access to their target information.
