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 );
[in] The 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 that pbHash points to.
[out] The size, in bytes, of the returned pbHash.
