Hide "gets" method output, for passwords..

HI All,

I'm trying to find a platform independent way of hiding the STDOUT when a
password is being entered via the gets method...
I was able to hide all output in Linux by using Termios , but as you know
this doesn't work on Windows..

What would be nice , is a simple implementation of asterisks replacing the
actual characters displayed to STDOUT ...

Does anyone know if this is possible in Ruby?

Thanks,

draygen

I'm not sure because I haven't done this sort of thing myself, but I
imagine the highline gem is a good place to look.
