WSE1.0 to WSE3.0

I am upgrading a project from WSE 1 TO 3, I have the following code on the client

        Dim proxy As New TestWS.DataServiceWse
        proxy.Url = WSLocation
        Dim reqCtx As SoapContext = proxy.RequestSoapContext
        Dim tok As New UsernameToken(EmailAddress, Password, PasswordOption.SendHashed)
        reqCtx.Security.Tokens.Add(tok)
        reqCtx.Security.Elements.Add(New Signature(tok))
        Return proxy


And on the web service

 Private Function Authenticater() As Boolean

        Dim requestContext As SoapContext = HttpSoapContext.RequestContext
        Dim userToken As UsernameToken
   
        If requestContext Is Nothing Then
            Throw New SoapException("Only SOAP requests are accepted", _
                            SoapException.ClientFaultCode)
        End If

        For Each userToken In requestContext.Security.Tokens
            If TypeOf userToken Is UsernameToken Then
                If userToken.PasswordOption = PasswordOption.SendHashed Then
                    Return True
                    Exit For
                Else
                    Throw New SoapException("The password must be hashed", SoapException.ClientFaultCode)
                End If
            End If
        Next
    End Function

does anyone before I upgrade whether this will work with 3?
