GetHashFromFileW Function

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

This function has been deprecated in the .NET Framework version 4. Use the ICLRStrongName::GetHashFromFileW method instead.

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


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


[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.


[out] A byte array containing the generated hash.


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


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

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