Generate a CSR (Certificate Signing Request) inside cPanel


SSL Certificates are small data files that digitally bind a cryptographic key to an organization’s details. When installed on a web server, it activates the padlock and the https protocol and allows secure connections from a web server to a browser. Typically, SSL is used to secure credit card transactions, data transfer and logins, and more recently is becoming the norm when securing browsing of social media sites.

Why SSL? The primary reason why SSL is used is to keep sensitive information sent across the Internet encrypted so that only the intended recipient can understand it. This is important because the information you send on the Internet is passed from computer to computer to get to the destination server. Any computer in between you and the server can see your credit card numbers, usernames and passwords, and other sensitive information if it is not encrypted with an SSL certificate. When an SSL certificate is used, the information becomes unreadable to everyone except for the server you are sending the information to. This protects it from hackers and identity thieves.

In the tutorial below we will show you how you can generate a CSR certificate from inside your WHM/CPanel.

What is CSR? Is a certificate signing request (also CSR or certification request) is a message sent from an applicant to a certificate authority in order to apply for a digital identity certificate (SSL Certificate).


Make sure that the below requirements are ready before we start our tutorial.

  • You have WHM/Cpanel installed on your server. (If not yet you can follow this guide).
  • You have access to your Cpanel account.
  • You have SSL verification medium such as your admin email address. eg. admin@mydomain.tld
  • You have the required access rights.

Fill up the required information

Information about you and your service is important in generating a CSR. Without this information, the Certificate Authority (usually the one who provides universally valid SSL certificate.) will not be able to recognize you or your service. It will not know who to send the verification email to and who will own the SSL certificate.

First, login to your cpanel server at http://mydomain/cpanel or For a list of WHM/Cpanel ports please see below.

2082 cPanel TCP inbound
2083 cPanel SSL TCP inbound
2086 WHM TCP inbound
2087 WHM SSL TCP inbound
2089 cPanel license TCP outbound
2095 Webmail TCP inbound
2096 Webmail SSL TCP inbound

Then go to Security > SSL/TLS. After that, click on "Generate, view, or delete SSL certificate signing requests."

You will then be redirected on another page where you can type your information. Fill up the form and click "Generate".
