帮忙把VB6代码改成ASP代码

Public Function Encode(ByVal S As String, ByVal key As String) As String
On Error GoTo err
If Len(S) = 0 Then Exit Function
Dim Buff() As Byte
Buff = StrConv(S, vbFromUnicode)
Dim i As Long
Dim j As Byte
Dim k As Byte, m As Byte
Dim mstr As String
mstr = key
Dim outs As String
i = UBound(Buff) + 1
outs = Space(2 * i)
Dim Temps As String
For i = 0 To UBound(Buff)
Randomize Time
j = CByte(5 * (Math.Rnd()) + 0) '
Buff(i) = Buff(i) Xor j
k = Buff(i) Mod Len(mstr)
m = Buff(i) \ Len(mstr)
m = m * 2 ^ 3 + j
Temps = Mid(mstr, k + 1, 1) + Mid(mstr, m + 1, 1)
Mid(outs, 2 * i + 1, 2) = Temps
Next
Encode = outs
Exit Function
err:

End Function

asp里vbs数据类型太弱，建议直接在VB里改成ActiveX在asp中引用，这样简单可靠。
