说明：通过随机产生密码，然后将密码EMail给注册用户，你可以确认用户的EMail填写是否正确。自动产生的密码往往安全性更高，同时，你可以过滤那些无效的用户。


把下面的代码保存为random.asp文件：

<%
Sub StrRandomize(strSeed)
        Dim i, nSeed
        nSeed = CLng(0)
        For i = 1 To Len(strSeed)
                nSeed = nSeed Xor ((256 * ((i - 1) Mod 4) * AscB(Mid(strSeed, i, 1))))
        Next

        Randomize nSeed
End Sub



Function GeneratePassword(nLength)
        Dim i, bMadeConsonant, c, nRnd

        Const strDoubleConsonants = "bdfglmnpst"
        Const strConsonants = "bcdfghklmnpqrstv"
        Const strVocal = "aeiou"

        GeneratePassword = ""
        bMadeConsonant = False

        For i = 0 To nLength
                nRnd = Rnd
                If GeneratePassword <> "" AND (bMadeConsonant <> True) AND (nRnd < 0.15) Then
                        c = Mid(strDoubleConsonants, Int(Len(strDoubleConsonants) * Rnd + 1), 1)
                        c = c & c
      i = i + 1
                        bMadeConsonant = True
                Else
                        If (bMadeConsonant <> True) And (nRnd < 0.95) Then
                                c = Mid(strConsonants, Int(Len(strConsonants) * Rnd + 1), 1)
                                bMadeConsonant = True
                        Else
                                c = Mid(strVocal,Int(Len(strVocal) * Rnd + 1), 1)
                                bMadeConsonant = False
                        End If
                End If
                GeneratePassword = GeneratePassword & c
        Next

        If Len(GeneratePassword) > nLength Then
                GeneratePassword = Left(GeneratePassword, nLength)
        End If
End Function

然后在你的目标程序中这样调用上面的代码，就可以实现密码的自动生成：(仅仅是一个例子，你可以把他们粘贴到一个Test.asp的文件中，然后运行Test.asp)

<!--include file="random.asp" -->

<%
'产生一个六位的密码

StrRandomize CStr(Now) & CStr(Rnd)
response.write GeneratePassword(6)

%>
<br><br>

<%

'产生一个8位的密码
StrRandomize CStr(Now) & CStr(Rnd)
response.write GeneratePassword(8)

%>
<br><br>


<%
'产生一个10位的密码
StrRandomize CStr(Now) & CStr(Rnd)
response.write GeneratePassword(10)
%>
<br><br>

<%

'产生1000个密码

dim t, t2
for t = 1 to 500
For t2 = 1 to 661
  StrRandomize CStr(Now) & CStr(Rnd)
next
StrRandomize CStr(Now) & CStr(Rnd)
response.write GeneratePassword(6)
response.write "<br>"
next
