I'm not clear on just what key files you're talking about.  There are several.

To generate a key,  use:

ssh-keygen -t dsa

and hit enter at all the prompts.  This will generate a dsa type key on your 
own machine.

Another file is   the known_hosts file which is create as you ssh to various 
hosts.
