How to encrypt data transfer on iPad for free while using public free wifi hotspot?

[killwin98]

All I could find were free apps, but then I need to buy a data plan. Is there a way to do it for free and without slowing too much my connection speed? I'm only concerned about websites that I use my passwords such as gmail, Facebook, etc.

Thanks!

most of the sites you mention use encrytion so the info is secure
FB and gmail both encrypt
if you look in the address bar and https - that means its encrypted and secure
i don't know about mac firewall, but you would set your windows firewall to public location and you would be protected from hacking. MAC software is very secure

hope this helps
