[/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:
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.
