Setup private keys for ssh on the raspberry pi

This one took me about 60 seconds to setup. Excellently easy on the raspberry pi and debian. This will setup private keys that act as an alternative to password logins. It allows for true one-click logins.

On the Raspberry Pi:

su
cd /root
mkdir .ssh
cd .ssh
ssh-keygen
cat id_rsa.pub > authorized_keys
chmod 600 authorized_keys

Now, copy id_rsa to your local computer and use that as your private key. If you are using putty, open puttygen and load the key, then save as a .ppk (putty private key) file and add to your putty config in the SSH section.
