ssh keys - howto?

[chip.wiegand at simrad.com]

Okay, I'm stumped. Just need to get ssh keys working. I have FBSD-5.1 web 
server with
sshd running. I have a workstation running W2K with WinSCP3. I have tried 
Puttygen to 
create the keys and copied the key to .ssh directory on FBSD, renamed it 
authorized_keys
but it don't work. I then ran ssh_keygen on the BSD box, but don't know 
what to do with the 
two files it created, there are no instructions about that part in the man 
file. Does anyone
have a how-to on settup of ssh between w2k and fbsd?
Thanks,
