# 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).
