用VBS實現(xiàn)PHP的md5_file函數(shù)代碼

    用VBS實現(xiàn)PHP的md5_file函數(shù)代碼,需要的朋友可以參考下，代碼主要是參考官方的資料。
    代碼如下:
    Function md5_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 = 3
    Stream.Type = 1
    Stream.Open
    Stream.LoadFromFile filename
    Do Until Stream.EOS
    HashedData.Hash Stream.Read(1024)
    Loop
    If raw_output Then
    md5_file = Utility.HexToBinary(HashedData.Value)
    Else
    md5_file = HashedData.Value
    End If
    End Function
