Detailed Steps to setup wildcard SSL certificate with domain and sub domain:

Following are the detailed steps to setup wild card SSL Certificate with your domain and Sub domains:

First of all we should have wild card SSL certificate purchased from CA. I have purchased SSL and hosting from godaddy : Please check properly few registrar provide SSL for their own server if you have hosting with them. Godaddy provide SSL Certificate for their hosing as well as if you have hosting with other provider. It depend on your requirements.

You can check other ssl provider below:





Login into your godaddy account and next Select  your Purchased certificate I have (Standard UCC SSL Certificate) ==> Click on Manage :

Generate CSR request to submit Certificate Signing Request (CSR). and Click on Re-Key certificate to submit CSR Request with CA for their approval.


Online and offline tool or utility can also help you to generate CSR Request




CSR generation Example with online tools you can fill your certificate see the details in below image :


Next copy the text from Information column and use putty or Opens SSL:

 openssl req -new -newkey rsa:2048 -nodes -out www_example_com.csr -keyout www_example_com.key -subj “/C=IN/ST=23/L=Chandigarh/O=Example Org/OU=Sales Dept./CN=www.example.com”

It will create www_example_com.csr  and www_example_com.key file on your desire location.

Copy www_example_com.csr file or by editing its content to paste in the Certificate Signing Request (CSR) Box:



Save and submit all Changes. Once CA will approve the Certificate it will be available for downloading. Click on Download and select your file for IIS/Apache or any other As i have selected for IIS. and extract the zip in your desired location. It has 2 files 1 like 755fadc3.crt and second has gd-g2_iis_intermediates (PKCS #7 Certificates (.p7b) file.

Next use convert gd-g2_iis_intermediates to .pem format $ openssl pkcs7 -in gd-g2_iis_intermediates -print_certs -out renderwebsols.pem

If Not then you will get the error:

Error: Unable to set the certificate: Invalid certificate format

Solutions: openssl pkcs7 -in gd-g2_iis_intermediates -print_certs -out renderwebsols.pem

Next Login into your Control Penal to setup SSL with your domain and go the Website & Domains


Select the website and click on “Secure Site with SSL” :



Now you have to “enable SSL support ” in your Plesk for your desired website.

  1. The “SSL Certificate” field should specify the certificate that was installed in step 7.
