Understanding SSL: The Backbone of Secure Online Communication
Known as Secure Sockets Layer, SSL is a pivotal encryption protocol that ensures the confidentiality of data transmitted between web servers and browsers.
Often referred to as TLS, or Transport Layer Security, this protocol utilizes certificates to verify the authenticity of the website you’re interacting with, providing users with peace of mind regarding their online interactions.
Activating SSL on your site switches your URL from HTTP to HTTPS, signified by a padlock icon next to your domain in the browser, indicating a secure connection.
Why SSL is Essential for Your WordPress Site
For WordPress site owners, implementing SSL is a critical step, as outlined in our comprehensive security guide. It’s not just about following best practices; it’s about maintaining the trust of your visitors.
Modern browsers like Google Chrome flag sites without SSL as ‘Not Secure,’ which can erode customer confidence and potentially drive them away.
Visitors should exercise caution on sites marked ‘Not Secure’ and avoid sharing personal details. Conversely, sites with SSL will display a padlock in the address bar, where users can click to view the site’s credentials.
Any WordPress site that collects personal information, whether it’s an eCommerce platform, a membership site, or any other type that requires login or payment details, should have a valid SSL certificate from a trusted Certificate Authority (CA).
The Mechanics of SSL Encryption
SSL functions by encrypting data sent between a visitor’s browser and the web server, safeguarding personal information from potential interception.
Your browser will automatically verify the SSL certificate of a website you visit. If the certificate is valid, the browser encrypts the data using the site’s public key before sending it to the server, where it is decrypted with the corresponding private key.
However, if the certificate is invalid, users will receive a warning about the insecure connection. Site owners must address these warnings promptly to prevent losing visitors.
Acquiring an SSL Certificate for Your Site
Many top-tier WordPress hosting providers now include free SSL certificates. If your host doesn’t offer this, services like Domain.com are available for purchasing an SSL certificate at competitive rates, complete with a security warranty and a TrustLogo seal.
For those starting a blog or creating a small business website on a budget, there are ways to secure a free SSL certificate, which we detail in our beginner’s guide.
Setting Up SSL on Your WordPress Website
After obtaining your SSL certificate, you’ll need to activate it for your domain and configure your WordPress site to use HTTPS. It’s also crucial to inform Google about the SSL implementation to avoid any search engine optimization (SEO) complications.
Our beginner’s guide offers step-by-step instructions for installing SSL, including a simplified method for novices. Alternatively, your hosting provider may be able to assist with the installation.
