DWORD dwPromptFlags;
HWND hwndApp;
LPCWSTR szPrompt;

Value Meaning - CRYPTPROTECT_PROMPT_ON_PROTECT
This flag is used to provide the prompt for the protect phase.
- CRYPTPROTECT_PROMPT_ON_UNPROTECT
This flag can be combined with CRYPTPROTECT_PROMPT_ON_PROTECT to enforce the UI (user interface) policy of the caller. When CryptUnprotectData is called, the dwPromptFlags specified in the CryptProtectData call are enforced.
