Manipulators with Parameters

Hi everybody. At first sorry for my poor english :|

I've got a problem with Manipulators with Parameters. I'm trying to code the encrypt(k) manipulator, which guarantees that coded (by k key) stream will be send to ostream, but i don't have any idea in what way can i do it.

i want to code this message "Paris is beatiful town" in this way:

cout<<encrypt(15)<<"Paris is beatiful "<<"town";

but only "Paris is beatiful" has coded. I want to code "town" too.
In other words i want my manipulator won't be a disposable function.

I hope that somebody's understood what i wrote.

I'll be very grateful for any help.
