GetHashFromFile Function

  • Article

Generates a hash over the contents of the specified file.

HRESULT GetHashFromFile (
      [in]  LPCSTR   szFilePath,
      [in, out] unsigned int   *piHashAlg, 
      [out] BYTE     *pbHash,    
      [in]  DWORD    cchHash,    
      [out] DWORD    *pchHash
);

Parameters

  • szFilePath
    [in] The 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 piHashAlgis 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 that pbHash points to.

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

Remarks

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