3/12/2014

This function obtains authentication information for a file.

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

• guidAuthClass
  [in] GUID that indicates the type of file to be authenticated. For more information, see Security Loader File Type Authentication GUIDs.

• 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.

Return Value

If it is successful, this function returns the value described in the following table. If the function is not successful, it returns a standard error code that indicates the cause.

Remarks

The caller should close the handle returned by this function by calling CloseHandle.
