/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.
ftpd(8) login(1), opie(4), opiekeys(5),
opiepasswd(1), opieinfo(1), su(1),
