The NCRYPT_PROTECT_STREAM_INFO structure is used by the NCryptStreamOpenToProtect and NCryptStreamOpenToUnprotect functions to pass blocks of processed data to your application.

Syntax

typedef struct NCRYPT_PROTECT_STREAM_INFO {
  PFNCryptStreamOutputCallback pfnStreamOutput;
  void                         *pvCallbackCtxt;
} NCRYPT_PROTECT_STREAM_INFO;

Members
