ssh and remote sudo not hiding password

If I understand you correctly you mean that I should use keys to
prevent the necessity for entering the password at all.  In fact I
already do this.  The password is not for the ssh connection but for
the sudo shutdown command.  How can I use ssh keys to prevent having
to enter pwd for sudo?
