You put the **private** key on the system you are connecting FROM, (in
your case this looks like Putty) and you put the **public** key on the
system you are connectiong TO. (in your case this looks like in
~/.ssh/authorized_keys)

The docs for putty, ssh, ssh-keygen should be helpful:

	http://www.tartarus.org/~simon/puttydoc/Contents.html

	man ssh-keygen
	man sshd # see end for authorized_keys file info

It is worth noting that putty can import/export
openssh keys.

Also you should check that the system administrator has not disallowed use
of public/private keys for ssh authentication. (see /etc/ssh/sshd_config
on the system you are connecting TO)
