Question:

What are the steps to install a Sectigo SSL certificate on IIS and F5 load balancer using pfx format?

I have purchased a Sectigo SSL certificate from a third-party vendor and received four crt files from Sectigo: one root, two intermediates, and one ssl. I need to convert them to pfx format and install them on my IIS server and F5 load balancer. The crt files are:

• AAACertificateServices.crt
• SectigoRSADomainValidationSecureServerCA.crt
• domain_com.crt
• USERTrustRSAAAACA.crt

Please

advise. Thank you.

Answer:

A Sectigo SSL certificate is a digital certificate that verifies the identity and encryption of a website. It is issued by Sectigo, a trusted certificate authority (CA) that provides various types of SSL certificates for different purposes and domains. To install a Sectigo SSL certificate on a web server and a load balancer, you need to have the certificate files in the appropriate format and follow the installation instructions for each device.

In this article, we will explain how to install a Sectigo SSL certificate on an Internet Information Services (IIS) server and an F5 load balancer using pfx format. Pfx is a file format that contains both the public key and the private key of the certificate, as well as the certificate chain that links the certificate to the root CA. Pfx files are also known as PKCS#12 files, and they are commonly used for Windows-based servers and devices.

The steps to install a Sectigo SSL certificate on IIS and F5 load balancer using pfx format are as follows:

1. Convert the crt files to pfx format. The first step is to convert the four crt files that you received from Sectigo to a single pfx file that contains the certificate, the private key, and the certificate chain. To do this, you can use a tool such as OpenSSL, which is a free and open-source software that can perform various cryptographic operations. The command to convert the crt files to pfx format using OpenSSL is:

“`bash

openssl pkcs12 -export -out domain_com.pfx -inkey domain_com.key -in domain_com.crt -certfile AAACertificateServices.crt -certfile SectigoRSADomainValidationSecureServerCA.crt -certfile USERTrustRSAAAACA.crt

“`

In this command, you need to replace `domain_com` with your actual domain name, and `domain_com.key` with the private key file that you generated when you created the certificate signing request (CSR) for your Sectigo SSL certificate. The output file, `domain_com.pfx`, will be the pfx file that you need for the next steps.

2. Install the pfx file on the IIS server. The second step is to install the pfx file on the IIS server that hosts your website. To do this, you need to access the IIS Manager, which is a graphical user interface that allows you to configure and manage your web server. The steps to install the pfx file on the IIS server are:

• Open the IIS Manager and select your server name in the left pane.
• Double-click on the Server Certificates icon in the middle pane.
• Click on the Import link in the right pane.
• Browse to the location of the pfx file and select it.
• Enter the password that you set when you created the pfx file and click OK.
• The pfx file will be imported and listed in the Server Certificates window.
• Select your website in the left pane and click on the Bindings link in the right pane.
• Click on the Add button and select https as the type of binding.
• Select the pfx file that you imported from the SSL certificate drop-down menu and click OK.
• The https binding will be added and your website will be secured with the Sectigo SSL certificate.

3. Install the pfx file on the F5 load balancer. The third step is to install the pfx file on the F5 load balancer that distributes the traffic to your web servers. To do this, you need to access the F5 Configuration Utility, which is a web-based interface that allows you to configure and manage your load balancer. The steps to install the pfx file on the F5 load balancer are:

• Open the F5 Configuration Utility and log in with your credentials.
• Navigate to System > File Management > SSL Certificate List and click on the Import button.
• Select PKCS 12 as the import type and browse to the location of the pfx file and select it.
• Enter the password that you set when you created the pfx file and click Import.
• The pfx file will be imported and listed in the SSL Certificate List.
• Navigate to Local Traffic > Profiles > SSL > Client and click on the Create button.
• Enter a name for the SSL profile and select the pfx file that you imported from the Certificate and Key drop-down menus and click Finished.
• The SSL profile will be created and associated with the pfx file.
• Navigate to Local Traffic > Virtual Servers and select the virtual server that corresponds to your website.
• Click on the Resources tab and select the SSL profile that you created from the SSL Profile (Client) drop-down menu and click Update.
• The SSL profile will be applied to the virtual server and your load balancer will be secured with the Sectigo SSL certificate.

By

following these steps, you can install a Sectigo SSL certificate on IIS and F5 load balancer using pfx format and ensure the security and encryption of your website and its traffic. If you have any questions or issues, you can contact Sectigo’s support team or your third-party vendor for assistance.
