Azure requires a pfx/p12 for its SSL Certificate installation. This file can only be generated from a Windows system or an application. You will never attain such a file from a Certificate Authority. Typically in order to get an SSL Certificate for your Azure cloud services Admins will use Windows Server IIS (Internet Information Services) to generate the pfx/p12 keypair used to import into Azure, but not everyone has IIS.

The Digicert Certificate Utility for Windows allows for the ability for admins to create the .pfx file needed for Azure systems without the need for a Windows Server.

This guide will carry you through the following:

  • CSR generation
  • SSL installation
  • Export of installed certificate as a pfx
  • Import pfx into Azure

These instructions assume that you already own your Windows Azure website, and that you have configured the domain name for your website. For more information, visit Microsoft’s Windows Azure page, or contact Microsoft.

Key features of the Digicert Certificate Utility that can help with the SSL Management  are..

SSL Certificate:

  • Generate a CSR for your SSL Certificate renewal or new order
  • Install certificates to pending requests
  • Re-install certificates in one click
  • Copy certificates between servers
  • Convert certificate into various formats

  • If you use the utility to generate a CSR for an SSL Certificate then once the certificate is issued you will have to import your SSL Certificate using the utility to successfully configure your SSL certificate to create a pfx file. 
  • The Digicert Certificate Utility for SSL Certificates Automatically refers to the Windows account certificate stores on the Windows system.

    azure install

    • IP based SSL: associates a certificate with a domain name by mapping the dedicated public IP address of the server to the domain name. This requires each domain name (domain.com, www.mysite.com, etc.) associated with your service to have a dedicated IP address. This is the traditional method of associating SSL certificates with a web server.
    • SNI based SSL: is an extension to SSL and Transport Layer Security (TLS) that allows multiple domains to share the same IP address, with separate security certificates for each domain. Most modern browsers (including Internet Explorer, Chrome, Firefox and Opera) support SNI, however older browsers may not support SNI. For more information on SNI, see the Server Name Indication article on Wikipedia.
  10. Click Save to save the changes and enable SSL. Your SSL certificate is now installed and configured for its website.

If you are unable to use these instructions for your server, Acmetek recommends that you contact either the vendor of your software or an organization that supports Microsoft.
