用VBS類比實現PHP的sha1_file函數效果代碼

複製代碼 代碼如下:Function sha1_file(filename, raw_output)
Dim HashedData, Utility, Stream
Set HashedData = CreateObject("CAPICOM.HashedData")
Set Utility = CreateObject("CAPICOM.Utilities")
Set Stream = CreateObject("ADODB.Stream")
HashedData.Algorithm = 0
Stream.Type = 1
Stream.Open
Stream.LoadFromFile filename
Do Until Stream.EOS
HashedData.Hash Stream.Read(1024)
Loop
If raw_output Then
sha1_file = Utility.HexToBinary(HashedData.Value)
Else
sha1_file = HashedData.Value
End If
End Function
