SSL stands for Secure Socket layer, it provides communication security over the internet. SSL encrypts the data using asymmetric cryptography, symmetric encryption & message authentication codes. All browsers support SSL and many websites use this protocol to obtain confidential information like Credit Card details over the internet. By convention you will need to use https:// instead of http:// in the browser address bar.

Today I am explaining the SSL process and installation of it on Linux Cpanel server .

Note: You will need to have root access of WHM control panel.

First you will need to generate CSR(Certificate Signing Request) in order to buy SSL from Crucial or Certificate Vendor (Geo trust, Rapid SSL or Symantec etc.)

Also you will need to create one of the following email address of the domain which you are getting SSL for. It is required as SSL vendor will email this account and request approval for your SSL order:
– [email protected]
– [email protected]
– [email protected]
– [email protected]

To generate a CSR from your control panel, you will need to have following information ready:
1. Email address:  (where certificate is sent)
2. Host to make Cert for: (Domain name with or without www. as prefix)
3. Country: (AU)
4. State: (NSW)
5. City: (Sydney)
6. Company Name: (Crucial)
7. Company Division: (Technical)
8. Email address (displayed in cert)
9. Password
10. Key Size (2048 bits)

Don’t forget to replace the details with your own details.

Note: Double check whether you need SSL for your domain with or without www.

Login into your WHM -> find ‘Generate a SSL certificate & Signing Request’

Fill up all the details and then click create.

It will generate Certificate signing request, Self signed certificate and RSA private Key. You will need to copy Signing Request and Key in a file and save it.

The CSR and Key will look like this:

After this you can submit the SSL certificate request with SSL Vendor using the generated CSR. Then you will get an approval email request on the above created email address to approve it. It will take 24 hrs to process your SSL request and valid certificate issued.

SSL Certificate requires a dedicated IP address that is unused and not shared with any other domain. So you will need to assign a dedicated IP address (using WHM -> ‘Change Site’s IP Address’) to the domain that you are installing SSL for.

Once you receive valid Certificate from SSL Vendor, Login to your WHM control panel:

Find ‘Install a SSL Certificate and Setup the Domain’ option and then copy the Certificate received from SSL vendor in first box without any white space in the end or beginning.

Then press Tab button on your key board. Rest of the details should be filled automatically and then hit Submit button to install SSL.

You will receive message that its been installed.

You can verify the installation of SSL on this URL:  http://www.sslshopper.com/ssl-checker.html

If you have any issue then you can email to our technical support team : [email protected]
