The NCryptOpenStorageProvider function is a core part of the Windows Key Storage Provider (KSP) architecture. A key feature of this function is its , which allows developers to access cryptographic storage operations without needing to know the specific implementation details of the underlying hardware or software provider. Key Feature: Uniform Provider Access
NCryptFreeObject(hProvider);
// 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) ncryptopenstorageprovider new
: Unlike primitive providers (functions starting with B ), the storage provider (functions starting with N ) is specifically designed for persisting and loading keys.
Microsoft Platform Crypto Provider ( MS_PLATFORM_CRYPTO_PROVIDER ) : L"Microsoft Platform Crypto Provider" The NCryptOpenStorageProvider function is a core part of
– The provider returns an opaque handle representing an open session to that storage subsystem (software file system, TPM driver, smart card middleware, etc.).
When you call new , the system first validates the incoming configuration flags. Typical parameters include: Use the provider (example: create a key container)
is the bridge between these two worlds. It is a software component that implements the OpenStorage API while injecting an Ncrypt filter driver into the I/O path. Every read or write pass through this filter, where encryption/decryption happens before the data touches the physical disk.
When refreshing a key, the NCryptCreatePersistedKey function can use flags to manage existing keys. 4. Key Storage Providers (KSPs) Available
If you’ve come across ncryptopenstorageprovider new , you’re likely working with (a data-at-rest encryption layer) or a custom storage provider integration. This command typically initializes a new storage provider instance for encrypted volume management.
