NAME
       opiegen - Example OPIE-based OTP generator

SYNOPSIS
       opiegen
       [ challenge ]

DESCRIPTION
       opiegen	takes a properly formed OTP challenge either
       from the command line or from standard input, prompts
       the  user  for a secret pass phrase, and generates an
       OTP response to that challenge. It is intended as  an
       example for programmers of how a simple OTP generator
       can be built. Users should probably use	the  opiekey
       program instead.

EXAMPLE
       wintermute$ opiegen otp-md5 495 wi01309
       Secret Pass Phrase:
       GILL HUED GOES CHUM LIEU VAIN
       wintermute$

BUGS
       opiegen(1)  can	lull  a	 user into revealing his/her
       password when remotely logged in, thus defeating	 the
       purpose	of  OPIE.  This is especially a problem with
       xterm.  opiegen(1) implements simple checks to reduce
       the risk of a user making this mistake. Better checks
       are needed.
