Syntax

HRESULT LoaderVerifierAuthenticateFile(
    __in const GUID*        guidAuthClass,
    __in_opt HANDLE         hFile,
    __in LPCWSTR            szFilePath,
    __in_opt LPCWSTR        szHashHint,
    __in HANDLE             hReserved,
    __out LPHANDLE          phslauthnFile
);

Parameters

  • hFile
    [in] Handle to the file to be authenticated. This may be NULL for some file types (for example, the type LV_AUTHENTICATIONGUID_ROM_EXE).
  • szFilePath
    [in] Full path to the file to be authenticated.
  • szHashHint
    [in] Identifier of a hash algorithm, which requests that the Loader Verifier calculate the hash of the file using that algorithm. Typically, a program specifies this parameter before later calling the LoaderVerifierGetHash function. If the caller does not need a specific hash, pass NULL.
  • hReserved
    [in] Reserved for future use. Set this parameter to NULL.
  • phslauthnFile
    [out] Pointer to the variable that receives a handle to the authentication information for the file.
