Any way to GPG-encrypt files from Nautilus

I'm not by my Fedora Core 3 box so I can't say what the state of the
art is in GNOME. My question is: there is a little Windows application
called WinPT which is a wrapper over GnuPG with some GUI goodies. One
of said goodies is a context menu extension to encrypt a file. You
right-click on a file and poof, it creates a file with the same name
ending with ".gpg", encrypted to the public key(s) of your choosing.
Quite handy.

I wonder if there's something similar for Nautilus?
