Microsoft's official documentation warns that calling this function within a service's StartService function can cause a deadlock , potentially making the service stop responding.

Third-party vendors (e.g., Thales, Gemalto, AWS CloudHSM, Azure Key Vault) install their own KSPs. NCryptOpenStorageProvider allows applications to target these specific hardware modules simply by passing the vendor's registered provider name. This allows code to remain hardware-agnostic; switching from a software key to an HSM key often requires only changing the string passed to this function.

In the legacy CryptoAPI (CAPI), the equivalent function was CryptAcquireContext .

CNG is designed to isolate keys. The provider loaded via this function typically isolates keys by user profile. If a process is running under a specific user account, the provider will generally only have access to that user's keys unless the application performs impersonation or accesses machine-level key stores. ncryptopenstorageprovider
