/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. |
