+#!/bin/sh
+#
+# usage: onetimekey path/to/mycert.pem
+#
+# Takes an openssl cert+key pem file and turns into a long string
+# for the x11vnc SSL VNC Java Viewer.
+#
+# The Java applet URL parameter can be  oneTimeKey=<str> where str is
+# the output of this program, or can be oneTimeKey=PROMPT in which
+# case the applet will ask you to paste in the string.
+#
+# The problem trying to be solved here is it is difficult to get
+# the Java applet to have or use a keystore with the key saved
+# in it.  Also, as the name implies, an HTTPS server can create
+# a one time key to send to the applet (the user has already
+# logged in via password to the HTTPS server).
