Follow the prompts and use the defaults for the filenames it gives you. Don’t enter in a password.
2. Go to the finder menu Go|Go to Folder and type in ~/.ssh
You should then have two new files id_rsa and
3. Use your ftp program to copy into the .ssh directory in the home folder on your server machine, and rename it to authorized_keys.
