How does tor encrypt my data?

Similar to what F. Fox wrote yesterday:
If you don't use end-to-end encryption (e.g. https, pop3s, imaps, ssh, and/or 
own encryption (e.g. gnupg)), you trust the exit node and all systems in 
between the exit node and your destination server.
Like always, if you surf the web unencrypted. Tor only helps you to stay 
anonymous. The exit node, destination and systems in between cannot easily 
identify you if you don't send (personal) information, which can identify you, 
but they can read and change the transported data.
