How to install SSL Certificates in 2023

Websites need to install SSL to have a secure connection. This certificate encrypts the information transferred between the site and the user. Therefore, all information is securely transferred between the browser and the server, limiting the access of individuals such as hackers to this information. Another benefit of installing SSL for your business is that you can attract more user trust to your site.

In this tutorial guide, we examine how to install SSL in different control panels. But before starting this tutorial, you need to familiarize yourself with SSL.

What is an SSL Security Certificate?

The term SSL stands for Secure Sockets Layer, which is used for security certificates. This certificate consists of small information files that help users to exchange information between the user and the website in a secure environment. The default protocol of websites is HTTP. But after installing SSL, this protocol changes from HTTP to HTTPS, and a secure connection is established between the browser and the web server.

You can identify the activation of this certificate on a website from the “S” at the end of the HTTPS protocol. Also, a lock sign is displayed before the address in the URL. This certificate plays the role of a security provider for information transfer. Since part of people’s activity on websites is related to the transfer of important and confidential information and logging into the user profile, creating such a secure platform for user use seems necessary. The following are some of the benefits of SSL:

  • Increased security related to transactions made with credit cards
  • Preserving the security of websites that deal with confidential and valuable user information
  • Preserving the security of online stores and the like

Website owners have a duty to protect user information against hacker attacks, and SSL creates such a platform. Since security is a valuable factor for Internet users and SSL has the duty of adding this security layer to your website. Read more: My Website Has Been Hacked

What is HTTPS?

HTTPS is the encrypted version of the HTTP protocol that uses the SSL certificate to encrypt the connection between the client and the server. Using this protocol for exchanging sensitive information such as banking information, username, and password at high-security levels is very important and significant.

Why should we use SSL certificates?

Companies and organizations should add SSL certificates to their websites to secure online transactions and keep customer information private and secure. In short, SSL is responsible for keeping security information safe and prevents criminals from reading or changing information transferred between two systems.

Unfortunately, there are still many websites in the world that are not aware of the importance of purchasing SSL for their site. This means that the admin access information of such sites is at risk of hacker and phisher abuse and user information theft.

If you don’t want to pay for SSL and don’t have a large website, you can use Let’s Encrypt’s free SSL. But keep in mind that free SSL certificates are renewed in 1 to 3-month periods, but with payment, you can buy this certificate in 1 or 2-year periods.
