openssh unix dev - Feb 2004 - Key exchange

Hi,

I would like to know the order used by OpenSSH to choose the key exchange 
algorithm.

I've used Ethereal to sniff a complete connection between my FreeBSD 
workstation and my OpenBSD laptop. I found that ssh used Diffie-Hellman.
Why ?

How can I use RSA or DSA keys created during the first boot by /etc/rc ?

Please note that I'm not asking how to use keys to access a box, but how to 
choose a different algorithm to manage the key exchange process and protect 
my password on the wire...

Thanks.

I think you need to read the protocol spec:

this is how ssh works.

they are.
