An SSL certificate is helpful in protecting your users from cyber attacks. It also builds a level of trust with your website visitors.
SSL is an abbreviation for Secured Socket Layer. It’s an encryption protocol that protects data in transit. Although the SSL abbreviation has stuck, modern SSL certificate actually use TLS (or Transport Layer Security), a more modern and more secure version of SSL.
While most SSL certificates are usually expensive to acquire, there are a few ways to get an SSL certificate at zero cost for your WordPress site.
This is what we will show you in this step-by-step guide but first of all, let’s talk about why your WordPress website needs an SSL Certificate.
Why Your WordPress Website Needs An SSL Certificate
An SSL certificate is not just for websites that collect and process payment and personal information. It’s one of the most reliable ways of assuring the user that they can trust your website.
By encrypting the information flow between the client and the server, the SSL certificate minimizes the chances of a successful man-in-the-middle attack.
Because it’s such an essential part of securing a website, modern browsers no display prominent warnings whenever you try to access a page that is not protected by an SSL certificate. If you don’t have one, your search engine rankings are also likely to suffer.
In other words, there’s no excuse for ignoring the need for an SSL certificate, regardless of the type of website you’re running.
How an SSL Certificate Works
Now that you understand that having an SSL certificate for your WordPress website is essential. You want to know how an SSL certificate works in reality.
When a user visits a website with an SSL certificate installed, their browser first verifies that the installed certificate is valid.
The browser and the server then negotiate the encryption algorithm and start the so-called TLS handshake. During it, they exchange information encrypted with a public key that can only be decrypted with the certificate’s private key. With the handshake complete, another encryption key is generated. This is the one that will encrypt the information exchange during the session.
It’s a complex algorithm that involves both symmetric and asymmetric encryption and ensures the connection is secure.
What is Let’s Encrypt
Let’s Encrypt is a certificate authority that gives out free SSL certificates to all website owners.
If you have a ScalaHosting account, a Let’s Encrypt certificate will be issued and installed automatically as soon as you point your domain to our servers.
You can also manage your free and paid certificates from the SSL Certificates section inside SPanel’s User Interface.
How To Activate Free SSL In WordPress
After enabling an SSL certificate for your WordPress, we will go ahead to activate it on the website.
This activation updates your URL from HTTP to HTTPS indicating that the website is now secure. The SSL certificate won’t work, even after it has been enabled, until the URL is updated.
To activate the free SSL in WordPress, log in to your WordPress administration dashboard
Next, go to the Settings option
Click on General
Change your WordPress URL and Site URL to HTTPS
Click Save
This process works well if your website is new. However if you have a website already indexed on Google, some of its pages might still load as HTTP and others as HTTPS. This might become worrisome as a website administrator.
Thankfully, there is an easy way out. A few WordPress plugins like ‘Really Simple SSL’ and ‘SSL Insecure Content Fixer’ help to detect website’s SSL status and run all pages on HTTPS
How To Update Your Website URL Using Plugins
Log in to your WordPress Administrator dashboard
Go to the plugin option
Click on Add New Plugin
Click on Upload Plugin
Upload the downloaded plugin file, Click on Install Now
After installing the plugin, click on Activate
The activated plugin, automatically detects HTTP pages and runs them on HTTPS.
