There's two things to note here. The short answer is "yes".

However you don't "install" onto a USB stick using USB creator. So
when you use USB creator from an ISO image or CD to make a bootable
USB stick you're essentially coping the live environment into the USB
stick. Once done you then have a bootable USB stick you can install
_from_.

If you _install_ _onto_ a USB stick then you lose the ability to
install from there, because you're no longer running a live
environment on the USB stick, but a fully installed one, just as if
you'd installed on a hard disk in a computer. Albeit a very small hard
disk that is highly portable.

I created my 32GB USB stick by booting to Ubuntu off a CD. Then
installed to the USB stick and used the standard encryption option in
the installer.

It works if you use the installer and not USB disk creator.
