.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
program initializes and updates your current series of one-time
|
|
passwords (OTPs).
|
|
.Pp
|
|
Use this to set a new series of one-time passwords. Only perform this
|
|
on the console or over an encrypted link as you will have to supply
|
|
your pass-phrase. The other two parameters are
|
|
.Ar sequence-number
|
|
and
|
|
.Ar seed .
|
|
.Pp
|
|
Options are:
|
|
.Bl -tag -width Ds
|
|
.It Fl d
|
|
To delete a one-time password.
|
|
.It Fl f
|
|
Choose a different
|
|
.Ar algorithm
|
|
from the default md5. Pick any of: md4, md5, and sha.
|
|
.It Fl h
|
|
For getting a help message.
|
|
.It Fl l
|
|
List the current table of one-time passwords.
|
|
.It Fl o
|
|
To open (unlock) the otp-entry for a user.
|
|
.It Fl r
|
|
To renew a one-time password series. This operation can be performed
|
|
over an potentially eavesdropped link because you do not supply the
|
|
pass-phrase. First you need to supply the current one-time password
|
|
and then the new one corresponding to the supplied
|
|
.Ar sequence-number
|
|
and
|
|
.Ar seed .
|
|
.It Fl u
|
|
To choose a different
|
|
.Ar user
|
|
to set one-time passwords for. This only works when running
|
|
.Nm
|
|
as root.
