In many API documentation versions, the "New" concept is implemented via the flag or context-specific flags that force the creation of a new provider context. However, in modern implementations and enterprise wrappers (such as those found in .NET Interop or PowerShell), the term "New" implies the following distinct behaviors: The Standard dwFlags options include: | Flag | Behavior | | :--- | :--- | | 0 | Opens the default instance of the provider. If the provider is already opened elsewhere in the process, you may receive a handle to the same instance. | | NCRYPT_NEW_PROVIDER (Conceptual) | Forces the creation of a fresh provider context. This is often mapped to NCRYPT_SILENT_FLAG or specific allocation flags that prevent reuse of cached handles. | | NCRYPT_SILENT_FLAG | Prevents UI dialogs from appearing (useful for background services). | | | NCRYPT_NEW_PROVIDER (Conceptual) | Forces the creation
