How do I import a public certificate to Windows Azure?

I am going to communicate from Windows Azure to another public web service through SSL. And the certificate on public web service is self-signed. Therefore I need to trust the public certificate on my Windows Azure.

How can I import the certificate (.cer) to Windows Azure? The management portal only allow import a certificate with private key.

How do I import a certificate into Windows?

In the left pane of the console, double-click Certificates (Local Computer). Right-click Personal, point to All Tasks, and then select Import. On the Welcome to the Certificate Import Wizard page, select Next. On the File to Import page, select Browse, locate your certificate file, and then select Next.

This is actually an issue with the portal, not with azure itself. Go to the "Add Certificate" section in the portal, click the browse button, navigate to where your .cer file is. The files listed are filtered to .pfx files so you won't see the file you want to import, but, if you type in the name of the file it will work.
