+This command will create a pair of private key (''~/.ssh/id_rsa'') and public key (''~/.ssh/id_rsa.pub''). To enable authentication on a remote host, append the public key to the ''~/.ssh/authorized_keys'' file in the remote host (this file should be owned by the user and have the ''644'' permissions).
 If the home directory is encrypted, ''authorized_keys'' would not work while within the home directory before the user is logged in. Move the ''authorized_keys'' file and modify ''/etc/ssh/sshd_config'' accordingly.
