The system will then generate your key :

Your identification has been saved in /home/me/.ssh/id_rsa. Your public key has been saved in /home/me/.ssh/ The key fingerprint is: d2:76:59:24:4e:ee:07:59:cd:0d:8b:ef:61:f9:05:83 me@mysystemThe site administrators need the contents of the file to enable access.
