Sometimes we have to go places where no trusted machines or
connections are available. In this case, it is possible to use the
`key' command to generate a number of one-time passwords in the same
command; these can then be printed out. For example:
$ key -n 25 57 zz99999
Reminder - Do not use this program while logged in via telnet or rlogin.
Enter secret password:
33: WALT THY MALI DARN NIT HEAD
34: ASK RICE BEAU GINA DOUR STAG
[...]
56: AMOS BOWL LUG FAT CAIN INCH
57: GROW HAYS TUN DISH CAR BALM
The `-n 25' requests twenty-five keys in sequence; the `57' indicates
the ending iteration number; and the rest is as before. Note that
these are printed out in reverse order of eventual use. If you're
really paranoid, you might want to write the results down by hand;
otherwise you can cut-and-paste into `lpr'. Note that each line shows
both the iteration count and the one-time password; you may still find
it handy to scratch off passwords as you use them.
