# opiekeys(5)

OPIE database of user key information

## 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 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.
```
