The main reason to install an SSL certificate on your website is to encrypt sensitive information between your visitor and your website. Most text sent from your browser to a website is in plain text and can be accessed by anyone “listening” in. Using an SSL connection (https), the connection is encrypted. So if someone were “listening”, they would just see random letters and numbers. This is required when transferring username, passwords and any credit card information.
If you have a website that is for information purposes only, and users can not input any sensitive data onto your site, then an SSL is not needed. But if you have users logging into your site with a username and password, and using credit cards, then an SSL is needed.
Below I will show you how to install the very simple Let’s Encrypt SSL certificate.
How to install Lets Encrypt SSL
You first need to log into your cPanel. So to do, that it will be yourdomain.com/cpanel. Then enter in your username and password given to you by your host. If you don’t have it, or can not remember it, contact your host.
Once logged in, click on the Lets Encrypt SSL icon under the security section
Next, click on the +Issue link on the right side of your domain you want to install the SSL.
Then click on the check box under the Include column, and the check box beside “Install mail SMTPS/POP3S/IMAPS SSL certificate for yourdomain.com”. Then click the Issue button below
Once the installation has completed, you will get a message indicating that the SSL is now installed on your domain.
You may now access your site using the https. If you are using WordPress, you will need to make changes for it to work. Log into your WordPress Admin, and click on Settings > General
Add the “S” at the end of the http to make it https for both WordPress Address (URL) and Site Address (URL)
Note: If you check off the second box for mail, you then can connect to your mail accounts securely as well. So email send from your device/PC to server will be encrypted
