作者: s700800900 时间: 2010-7-28 11:28 标题: [已解决]VBS怎样计算文件MD5值?
如下是从网络上搜到的函数,但我在使用过程中出现ActiveX控件无法创建对象CAPICOM.HashedData,弄了许久,无果,在此求解。- '获得文件的MD5值
- Function MD5Sum(filename)
- Set MyStream = CreateObject("ADODB.Stream")
- MyStream.Type = 1
- MyStream.Open()
- MyStream.LoadFromFile(filename)
- Set MyHashed = CreateObject("CAPICOM.HashedData")
- MyHashed.Algorithm = 3
- MyHashed.Hash(MyStream.Read())
- MyStream.Close
- MD5Sum = MyHashed.Value
- End Function
-
- '要获取字符串的MD5值的话,需要先把字符转成二进制格式:
-
- Function str2strb(str)
- For i = 1 to Len(str)
- tmp = Mid(str, i, 1)
- restr = restr & chrB(ascB(tmp))
- Next
- str2strb = restr
- End Function

那时人家封装好的三方组件……
你要用需要dll或者ocx。
MD5的算法好像有VBS版的,但是是字符串的,文件的MD5的,建议还是找个3方调用下算了。

VBS算法我倒是有,不会,主要是调用别的程序出个黑框框,消黑框框的代码还没整明白。,算了,结贴吧。下面是VBS MD5的算法,说不定对以后搜到这贴的人有用。俺水平太低,看不明白。- Private Const BITS_TO_A_BYTE = 8
