CngKey.Import(…); succeeds on PC but fails on Web host

问题

The following line succeeds on my PC but throws an exception on a web host's server:

CngKey.Import(EccPrivateBlob, CngKeyBlobFormat.EccPrivateBlob);    //EccPrivateBlob is a byte[] that works on my PC.

The exception:

System.Security.Cryptography.CryptographicException: An internal error occurred. at System.Security.Cryptography.NCryptNative.OpenStorageProvider(String providerName) at System.Security.Cryptography.CngKey.Import(Byte[] keyBlob, CngKeyBlobFormat format, CngProvider provider) at ...

Is this a security exception? Is there a way around it?

I was able to resolve this by enabling WEBSITE_LOAD_USER_PROFILE = 1 in the Azure portal as mentioned here:

How can I sign a JWT token on an Azure WebJob without getting a CryptographicException?
