Help for ssh public_key

To set up public key authentication in PyLily, you just need to use SFTP or scp 
to upload a file named "ssh_authorized_keys" to the PyLily server. Use your 
PyLily username and password to authenticate when doing this file upload, and if
you succeed future logins will no longer prompt you for a password.

The "ssh_authorized_keys" file should be in the same format as a typical 
".ssh/authorized_keys" file in OpenSSH, containing a list of trusted SSH public 
keys or certificate authorities. The corresponding private key should be in your
client's ".ssh" directory or in something like an ssh-agent that your SSH client
is configured to use.
