Secure Socket Layer, or simply SSL, is a security protocol that encrypts the communication between a web server and a web browser. In this age of web vulnerability, WordPress SSL certificates provide an additional security layer by ensuring that the communication between a web server and a web browser is private.
When you visit a website, you will notice that the URL is either HTTP or HTTPS. The S in the HTTPS refers to the SSL certificate. Good crawlers also take this into consideration when they are compiling SERPS. A website with WordPress SSL certificate is given preference.
Google Chrome started marking websites without WordPress SSL as “Not Secure”. This resulted in visitors avoiding engagement on such websites. Site owners experienced a decline in conversions like sales, subscription, and more.
What is an SSL Certificate?
Secure Socket Layer (SSL) encrypts the transferred data between a web server and a web browser. When you install a WordPress SSL certificate on your website, you will notice your HTTP protocol changing to HTTPS.
How Does a WordPress SSL Certificate Work?
SSL certificate converts your HTTP protocol into an HTTPS protocol by encrypting the data that is transferred from a web server to a web browser. This process of data encryption involves a user submitting information which can include name, credit card number, home address.
This data is then encrypted and transported from HTTPS to your web server. Any attempt of a data breach will not leak out the information because it is encrypted.
Types of WordPress SSL Certificates
Single domain SSL certificates can only be used on a single domain or a single IP address at a time.
Multi-domain SSL certificates can be used on more than one domains.
A Wildcard SSL certificate is used on a single domain but can be extended to multiple sub domains.
As the name suggests, the multi domain wildcard is a hybrid of both, multi domain and a wildcard SSL certificate. This means that the SSL certificate can be used on multiple domains and also multiple sub domains.
