.SH NAME
opiegen \- Example OPIE-based OTP generator

.SH SYNOPSIS
.B opiegen
.sp 0
[
.I challenge
]
.sp 0

.SH DESCRIPTION
.I 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
.I opiekey
program instead.

.SH EXAMPLE
.sp 0
wintermute$ opiegen otp-md5 495 wi01309
.sp 0
Secret Pass Phrase:
.sp 0
GILL HUED GOES CHUM LIEU VAIN
.sp 0
wintermute$
.LP

.SH BUGS
.BR 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. 
.BR opiegen(1)
implements simple checks to reduce the risk of a user making
this mistake. Better checks are needed.
