The Enhanced TightVNC Viewer, SSVNC, adds encryption security to VNC connections.
The package provides a GUI for Windows, Mac OS X, and Unix that
automatically starts up an STUNNEL SSL tunnel for SSL or ssh for SSH
connections to x11vnc or any other VNC
server, and then launches the VNC Viewer to use the encrypted tunnel.
The provided unix viewer, ssvncviewer, has many enhancements
over regular viewers.
