Programmatically change management cert for multiple (600+) subscriptions

Question

Our service has 600+ subscriptions, and they all share the same management cert.
Due to security reason, we would like to change management cert on the subscriptions periodically, but I have not yet found a way to do so programmatically.
I have found the "Add Service Certificate" cmdlet but it only allows you to upload the "Service certificate per service",
and I need to be able to change "Management cert" for all 600+ subscriptions.
Could you please tell me if there is a programmatic way to do so?

Answer 1

I'v just write a blog show how to use Managment class libraries.
You can refer to my
blog, or Download the
code sample I upload to MSDN and add the managment class libraries to your project.
Then Add Certificate like this:
ComputeManagementClient client = new ComputeManagementClient(cloudCredentials);
ServiceCertificateCreateParameters parm = new ServiceCertificateCreateParameters()
Data = certByte,//the certificate your want to add(convert to byte[] the certificate should be pfx )
CertificateFormat = CertificateFormat.Pfx,
Password="YouPassword"
var hostedServices = client.HostedServices.List();
foreach (var service in hostedServices)
client.ServiceCertificates.Create(service.ServiceName, parm);
Console.ReadLine();
