38. Configuring SSL and HTTPS in WordPress

Online security is a growing concern for website owners and internet users. One of the most effective ways to protect a website and the information it transmits is through the implementation of SSL (Secure Sockets Layer) and the use of HTTPS (Hypertext Transfer Protocol Secure). In this chapter, we will discuss the importance of SSL/HTTPS and how to configure it on your WordPress site, from basic to advanced.

Why is SSL/HTTPS Important?

SSL is a security protocol that establishes an encrypted connection between a web server and a browser. This ensures that all transmitted data is secure and inaccessible to third parties. HTTPS is the secure version of HTTP, which is the protocol used to send data between your browser and the website you are connected to. A website that uses HTTPS has an SSL certificate that authenticates the website's identity and encrypts information sent and received.

In addition to protecting data, SSL/HTTPS is also important for user trust and website credibility. Modern browsers like Chrome and Firefox mark websites without HTTPS as "not secure", which can negatively affect user perception and your website's reputation. Additionally, Google considers HTTPS as a ranking factor, which means sites with SSL tend to perform better in search results.

Obtaining an SSL Certificate

Before you can set up SSL/HTTPS on your WordPress site, you will need to obtain an SSL certificate. There are several options available:

Free Certificates: Services like Let's Encrypt offer free SSL certificates that are perfect for blogs and personal websites.
Paid Certificates: For businesses and e-commerce, it may be preferable to obtain a paid SSL certificate from a reputable Certificate Authority (CA), which can offer additional guarantees and security features.

After purchasing the certificate, you will need to install it on the server hosting your website. This is usually done through your hosting control panel, such as cPanel or Plesk, or you may need to contact your hosting's technical support for installation.

Configuring WordPress to Use HTTPS

With the SSL certificate installed, the next step is to configure your WordPress site to use HTTPS. Here are the basic steps:

Update Site Address: Go to your WordPress admin panel, navigate to 'Settings' and then 'General'. Update the 'WordPress Address (URL)' and 'Site Address (URL)' fields from 'http://' to 'https://'. Save the changes.
Redirection to HTTPS: To ensure that all visitors are redirected to the secure version of your website, add the following code to your website's .htaccess file:
```
RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.yourdomain.com/$1 [R,L]
```
Make sure to replace 'www.yourdomain.com' with your real domain.
Update Content and Internal Links: To avoid 'mixed content' warnings, you will need to update all internal links and references to resources (such as images, scripts, stylesheets) to use ' https'. There are plugins like 'Really Simple SSL' that can help automate this process.
Update Google Analytics and Webmaster Tools: If you use Google Analytics or any webmaster tools, don't forget to update your site's URL to 'https' so that data from traffic are tracked correctly.

Advanced Considerations

For advanced users, there are additional considerations when configuring SSL/HTTPS on a WordPress site:

Header Security Configuration: To further improve security, you can add HTTP security headers, such as HSTS (HTTP Strict Transport Security), which instruct browsers to connect to your site only through HTTPS.
Performance and Caching: SSL encryption may affect website performance. Use caching techniques and optimize your website's resources to mitigate any impact on loading time.
Plugin and Theme Compatibility: Make sure all plugins and themes are up to date and HTTPS compatible to avoid functionality or display issues.

Implementing SSL/HTTPS is essential for the security of your WordPress site and the trust of your users. By following the steps and considerations presented, you can ensure that your website is protected and optimized for a safe online environment.

Concludedare

Setting up SSL and HTTPS is a critical step in creating and maintaining a WordPress website. It not only improves security and privacy, but also contributes to your website's trustworthiness and ranking in search engines. Although the process may seem technical, most hosting providers and plugins make it easy to implement SSL/HTTPS. By ensuring that your website is secure, you are protecting not only your own information, but also that of your users, thus building a solid foundation for the success of your WordPress website.
