There are several 'flavors of keys' (and I am no expert) but I'll tell you 
about keys to ssh without passwords.
When you:
$ ssh-keygen
The program creates a public and a private key.
You can only decrypt with the private, anyone can encrypt with the public.
When you locate the public in the appropriate location, you can login 
without password in the other box.
There are 348695456 configuration variables to this...
