System.Security.Cryptography.CryptographicException: The profile for the user is a temporary profile

Aaah, security errors, you have to love them. When deploying a new service on IIS, I got the following error:

Server Error in '/SampleService' Application.

I was able to trace the source of the error to the following line in my code:

var certificate = new X509Certificate2(certificate, password);

This statement fails to work in IIS because the application pool user / IIS user doesn’t have the necessary permissions.  This is because the certificate that I load will be temporarily stored in a certificate store, which by default is the user store. And here rises the problem as the application pool / IIS user does not have rights to that certificate store.

To solve this issue we have to add an extra parameter to the constructor where we specify we want to (temporarily) store the certificate in the machine store:

var certificate = new X509Certificate2(certificate, password, X509KeyStorageFlags.MachineKeySet);

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
