.SH NAME
|
|
opiegen \- Example OPIE-based OTP generator
|
|
|
|
.SH SYNOPSIS
|
|
.B opiegen

.I challenge

.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 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.
