GetHashFromFileW Function

Generates a hash over the contents of the file specified by a Unicode string.

HRESULT GetHashFromFileW ( 
        [in]  LPCWSTR   wszFilePath,
        [in, out] unsigned int   *piHashAlg,
        [out] BYTE      *pbHash,
        [in]  DWORD     cchHash,
        [out] DWORD     *pchHash
); 

Parameters

• wszFilePath
  [in] The Unicode name of the file to hash.

• piHashAlg
  [in, out] The algorithm to use when generating the hash. Valid algorithms are those defined by the Win32 CryptoAPI. If piHashAlg is set to 0, the default algorithm CALG_SHA-1 is used.

• pbHash
  [out] A byte array containing the generated hash.

• cchHash
  [in] The maximum size of the buffer pointed to by pbHash.

• pchHash
  [out] The size, in bytes, of pbHash.

Remarks

This function is the same as GetHashFromFile, except that the file name specification is Unicode instead of ANSI.
