What is an SSL Certificate?

SSL, short for Secure Sockets Layer, is the tech that puts the ‘S’ in HTTPS..The protocol ensures that data is transferred securely between a browser and a website.

Every time an internet user visits a website, they transfer information. Such information might be sensitive:payment details, credit card info, and login credentials, etc.

By using the normal HTTP protocol, you open yourself up to hackers stealing your information. HTTPS or SSL will help you to fix this issue.

The URL of your website will also be surrounded by a reassuring lock once SSL has been installed. This allows your visitors to know that the data they will be submitting to your website are somehow safe.

Google gives a lot of weight to SSL certificates when it comes to SEO rankings. More importantly, a website with SSL turned on will display a comforting lock icon next to its URL, a signal to visitors that your site is secure.

Why SSL Certificates Are Crucial for WordPress Sites

If you’re running a WooCommerce website, a membership site, or any type of WordPress site with a login system, getting an SSL certificate is a must. Google may flag your site as “Not Secure” if you’re not running on HTTPS, which can dent your credibility and SEO ranking.

How Do SSL Certificates Work?

SSL uses public key cryptography to encrypt data. To send secure data between two systems, public key cryptography uses two keys – a private key and a public key. Encoding and decoding secure data require these two keys.

Using public key cryptography is like using a padlock. The public key is the padlock itself, and the private key is the combination. The server makes the padlock available to anyone to protect their data.

Nevertheless, the padlock cannot be opened without the server’s combination – which only the server knows.

Here’s how SSL functions:

  1. The user connects to a website, that is SSL-enabled.
  2. As part of the exchange, the user’s application requests the public key of the server. By using this public key exchange, both parties can encrypt messages that can only be read by the other party.
  3. The application encrypts the user’s message with the server’s public key when it sends it to the server.
  4. As soon as the server receives the message it decrypts it using its private key.

Installing an SSL certificate on WordPress is pretty straightforward. You can either do it manually or use plugins like Really Simple SSL to handle most of the work for you.

For an easy SSL transition, this plugin is ideal. Firstly, you need to install and activate Really Simple SSL. No extra configuration is required.

When you activate the plugin, it will check whether your SSL certificate has been enabled. Afterwards, it will enable HTTP to HTTPS redirect and set your website’s settings to use SSL/HTTP.

To make the most of your SSL certificate, you need to redirect your URLs from HTTP to HTTPS. Hopefully, Real Simple SSL will fixe your URLs automatically when the page loads through the plugin.

However, it catches non-secure URLs before the page loads, resulting in increased loading times. Therefore, advanced users who are concerned about WordPress speed might choose to redirect HTTP to HTTPS manually.

Manually Redirecting URLs from HTTP to HTTPS

Add these rules to your .htaccess file if you want to force your entire website to use https, but without using a plugin:

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://mydomain.com/$1 [R,L]

Simply replace mydomain.com with your actual domain name.

Then go to your WordPress admin area >> Settings >> General.
