rsync performs no encryption on its own. If you don't use ssh, nor do you tunnel the rsync traffic through stunnel or some kind of VPN, then no encryption is performed.
If you use the rsync:// protocol scheme (i.e. when you connect to a rsyncd daemon) then no encryption will be used (although password authentication is done using a MD4-based challenge-response system and is probably still reasonably secure).
If you use the hostname:/some/path scheme then rsync transparently calls SSH, which encrypts everything, and uses SSH's native authentication mechanisms.
