       [/etc/]opiekeys - OPIE database of user key information


       The  opiekeys  file contains user information used by the OPIE software
       to authenticate users. The opiekeys file is backwards  compatible  with
       the  S/Key  /etc/skeykeys  database  file,  but  only  if  the  hashing
       algorithm (MD4 and MD5) is the same between S/Key and OPIE  (i.e.,  MD5
       OPIE  cannot  use  MD4  S/Key  keys). The opiekeys file consists of six
       fields separated by spaces (tabs are properly interpreted,  but  spaces
       should be used instead) as follows:

       Field         Description
       name          User's login name.
       sequence      User's sequence number.
       seed          User's seed.
       key           User's last response (hex).
       date          Last change date.
       time          Last change time.
