Since the standard CNG does not export an explicit NCRYPT_NEW_PROVIDER flag, we simulate "New" by using NCryptOpenStorageProvider with the NCRYPT_SILENT_FLAG (to avoid cached UI prompts) and immediately disposing of any existing handles in the current scope.
SECURITY_STATUS OpenNewProvider(NCRYPT_PROV_HANDLE *phProvider) NCRYPT_MACHINE_KEY_FLAG
);
The system collects entropy from /dev/urandom, RDRAND (if available), and network jitter. A Data Encryption Key (DEK) is generated.
Example (conceptual C):
NCRYPT_PROV_HANDLE hProvider = NULL;
SECURITY_STATUS status = NCryptOpenStorageProvider(&hProvider, MS_KEY_STORAGE_PROVIDER, 0);
if (status == ERROR_SUCCESS)
// operate: NCryptCreatePersistedKey, NCryptOpenKey, etc.
NCryptFreeObject(hProvider);
In object-oriented programming and SDK design, the new keyword signifies instantiation. However, in the context of ncryptopenstorageprovider new, we are usually dealing with one of three scenarios:
When you run ncryptopenstorageprovider new, you are not just creating an object; you are bootstrapping a secure storage pipeline. ncryptopenstorageprovider new
Some providers (e.g., TPM provider) may require admin rights or specific user permissions. Check the return code and handle E_ACCESSDENIED gracefully.
The shift is toward declarative security. While ncryptopenstorageprovider new started as a CLI imperative command, the latest versions allow you to output an Operator configuration. Since the standard CNG does not export an
Instead of running new manually, you commit a CustomResourceDefinition (CRD) to Git:
apiVersion: storage.ncrypt.io/v1
kind: NcryptProvider
metadata:
name: production-provider
spec:
backend:
type: ceph-rbd
encryption:
algorithm: aes-256-gcm
keyRotationDays: 30
An operator watches for this CRD and internally executes the new logic. This bridges the gap between raw CLI power and modern GitOps workflows. The system collects entropy from /dev/urandom , RDRAND
The provider creates a hidden metadata block (first 4MB of the backend) containing:
