I've used passwords for my whole life--which is a terrible idea. I want to learn how to use keys but am stuck at this moment. So far I've generated myKey.pub and myKey.ppk but am not sure where to stick it onto the server and how to authorize my public key... I know where to import the private key into Putty and where to put the auto login, but am not sure how to get the public key authorized onto the server.
maybe this can help you along the way. http://www.happylife.sg/2007/08/07/how-to-setup-hostkey-authenication-for-ssh/
