NAME

       /etc/opiekeys - OPIE database of user key information

DESCRIPTION

       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 algo-
       rithm (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.
