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 %> |
