NCryptOpenStorageProvider is the gateway to modern key management on Windows. By implementing this function correctly, developers ensure that their applications take advantage of CNG's improved security, hardware support (TPM), and flexibility over legacy methods.

Abstract ncryptOpenStorageProvider (nOSP) is a proposed open, modular encrypted storage provider designed to give applications an easy-to-integrate, cross-platform interface for secure client-side encryption, key management, and storage abstraction. nOSP emphasizes privacy, minimal trust in backends, compatibility with existing cloud and local storage systems, and easy SDK integration for web, mobile, and desktop apps.

// 2. Use the provider (example: create a key container) NCRYPT_KEY_HANDLE hKey = NULL; status = NCryptCreatePersistedKey(hProvider, &hKey, NCRYPT_RSA_ALGORITHM, L"MyRSAKeyContainer", 0, 0); if (status != ERROR_SUCCESS) status = NCryptCreatePersistedKey(hProvider

: A pointer to an NCRYPT_PROV_HANDLE variable that receives the opened provider instance handle.

CNG separates storage from computation, allowing for better organization.
