在asp中通过vbs类实现rsa加密与解密

sp; lBytAscii = Asc(Mid(pStrMessage, lLngIndex, 1))
            lLngEncrypted = Crypt(lBytAscii, PublicKey)
            Encode = Encode & NumberToHex(lLngEncrypted, 4)
        Next
    End Function
    
    Public Function Decode(ByVal pStrMessage)
        Dim lBytAscii
        Dim lLngIndex
        Dim lLngMaxIndex
        Dim lLngEncryptedData
        Decode = ""
        lLngMaxIndex = Len(pStrMessage)
        For lLngIndex = 1 To lLngMaxIndex Step 4
            lLngEncryptedData = HexToNumber(Mid(pStrMessage, lLngIndex, 4))
            lBytAscii = Crypt(lLngEncryptedData, PrivateKey)
            Decode = Decode & Chr(lBytAscii)
        Next
    End Function
    
    Private Function NumberToHex(ByRef pLngNumber, ByRef pLngLength)
        NumberToHex = Right(String(pLngLength, "0") & Hex(pLngNumber), pLngLength)
    End Function

    Private Function HexToNumber(ByRef pStrHex)
        HexToNumber = CLng("&h" & pStrHex)
