How to Generate Certificate Signing Request (CSR) in WHM 11


WebHost Manager is the control center of the CPanel / WebHost Manager package. It is used to set up and manage accounts. This document provides CSR generation instructions for WHM 11. If you are not able to perform these steps on your server, RapidSSL recommends that you contact the server vendor or the organization, which supports WHM.

NOTE: To generate a CSR, you will need to create a key pair for your server. These two items are a digital certificate key pair and cannot be separated. If you lose your public/private key file or your password and generate a new one, your SSL Certificate will no longer match. 

To generate a Certificate Signing Request (CSR) file using WHM follow the steps below:

1.      Log in to WHM and from the menu, navigate to the 'SSL/TLS' section

2.      Click on the Generate an SSL certificate and Signing Request link in the SSL/TLS menu.

3.    Enter the email address to send the certificate to In the Email Address the Cert will be sent to field.

4.    In the Host to make cert for field enter the domain that the domain is being created for in the Host to make cert for field.

5.    Enter the administration details of the certificate in the Country, State, City, Company Name, Company Division, and Email fields

- Country Name (C): Use the two-letter code without punctuation for country, for example: US or CA.

- State or Province (S): Spell out the state completely; do not abbreviate the state or province name, for example: California.

- Locality or City (L): The Locality field is the city or town name, for example: Berkeley.

- Organization (O): If your company or department has an &, @, or any other symbol using the shift key in its name, you must spell out the symbol or omit it to enroll, for example: XY & Z Corporation would be XYZ Corportation or XY and Z Corportation.

- Organizational Unit (OU): This field is the name of the department or organization unit making the request.

- Common Name (CN): The Common Name is the Host + Domain Name.

NOTE: RapidSSL certificates can only be used on Web servers using the Common Name specified during enrollment. For example, a certificate for the domain "" will receive a warning if accessing a site named "" or "", because "" and "" are different from "". 

6.      Enter the password for the certificate in the Password field.

7.      Click Create

8.      Your CSR will now have been created.

9.      Verify your CSR

10.    Open the CSR in a text editor and copy and paste the contents into the online enrollment form when requested.
