This is a Windows utility to automatically start up STUNNEL to redirect SSL VNC connections to a remote host. Then TightVNC Viewer (included) is launched to used this SSL tunnel. An example server would be "x11vnc -ssl", or any VNC server with a 2nd STUNNEL program running on the server side. Just click on the program "ssvnc.exe", and then enter the remote VNC Server and click "Connect". Click on "Help" for more information information. You can also set some simple options under "Options ..." Note that on Windows when the TightVNC viewer disconnects you may need to terminate the STUNNEL program manually. To do this: Click on the STUNNEL icon (dark green) on the System Tray and then click "Exit". Before that, however, you will be prompted if you want ssvnc.exe to try to terminate STUNNEL for you. (Note that even if STUNNEL termination is successful, the Tray Icon may not go away until the mouse hovers over it!) With this STUNNEL and TightVNC Viewer wrapper you can also enable using SSL Certificates with STUNNEL, and so the connection is not only encrypted but it is also not susceptible to man-in-the-middle attacks. See the STUNNEL and x11vnc documentation for how to create and add SSL Certificates (PEM files) for authentication. Click on the "Certs ..." button to specify the certificate(s).

IMPORTANT: some of these binaries may have cryptographic software that you may not be allowed to download or use. See the above websites for more information and also the util/info subdirectories. Also, the kill.exe and tlist.exe programs in the w98 directory came from diagnostic tools ftp site of Microsoft's.
