[/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.
