But before we give you a list of SSL plugins you can use, we’ll talk more about SSL and why it is so important to have one. Understanding SSL, you will recognize the importance of SSL plugins for WordPress.

What is SSL?

To talk about the best WordPress SSL plugins in 2022, we first need to go back in time and explain what it is and its history. SSL stands for Secure Socket Layer, and it is a security protocol developed in ’90. Netscape Communications company developers, or to be more precise, Dr. Taher Elgamal, developed the original SSL protocol.

Its SSL version 1.0 had serious security issues and was never released. Version 2.0 was released, but it also had lots of issues with security and usability features. This version again couldn’t be used as security protection of any kind.

In 1996 a completely redesigned version of SSL, version 3.0, had been released, and the rest is history. All following SSL/TLS versions were based on this 3.0 SSL version. TSL is the new version of SSL, but the term SSL is still widely accepted and commonly used. TLS v1.3 was finalized in 2018.

The purpose of this protocol is to ensure safe communication on the networks. It uses authenticating and encrypting communication protocol during information and data transmission on the net. SSL protocol uses a digital certificate to secure connections between servers and clients.

Websites that want to download user data from a website domain must have a valid SSL certificate. A connection that doesn’t use an SSL certificate shouldn’t be trusted or used at all. We gave you a little introduction to the history of SSL, and now we’ll explain why you need it.

Why do you need it?

As already explained, SSL provides a secure connection between the server and the client. Usually, it is communication between servers and browsers (or other application that needs to connect to the server). SSL uses two protocols: The Handshake protocol and the Record protocol.

The handshake protocol, an HTTPS connection, is done automatically, and if this protocol fails, the client will be notified with an alert message in his browser. When the used SSL is valid, this protocol will have these security features: Authentication, Confidentiality, and Integrity.

To have a secure connection, you need to install an SSL certificate on your server once you obtain one. The HTTP connection is considered to be an insecure one, and messages with data exchanged between server and client using this connection can be read in plain text by hackers.

You will have a secure HTTPS protocol when you install an SSL certificate. All communication between server and client will be encrypted; therefore, it will be secured from hackers’ attacks. To quickly recognize if a website has an SSL certificate, pay attention to the URL. It should start with “https://.”

When you install an SSL certificate on your website, users will trust your site and will be ready to provide their data to subscribe to your site or purchase from it. Furthermore, SSL will improve your ranking on search engines, your site will be easier to find, and you will have more traffic.

Now that you understand the basics let’s talk about the best SSL plugins for WordPress in 2022.
