Se a informação pessoal, tal como uma palavra-passe da sessão, viaja pela Internet sem serem encriptada, esta pode ser facilmente intercetada por um espião. Se estiver a iniciar a sessão numa conta em qualquer site da Web, certifique-se que o site oferece encriptação HTTPS, que protege contra este tipo de espionagem. Pode verificar isso na barra de endereço: se sua ligação está encriptada, o endereço começará com “https://” em vez de “http://”.

The following visualization shows what information is visible to eavesdroppers with and without Tor Browser and HTTPS encryption:

  • Click the “Tor” button to see what data is visible to observers when you're using Tor. The button will turn green to indicate that Tor is on.
  • Click the “HTTPS” button to see what data is visible to observers when you're using HTTPS. The button will turn green to indicate that HTTPS is on.
  • When both buttons are green, you see the data that is visible to observers when you are using both tools.
  • When both buttons are grey, you see the data that is visible to observers when you don't use either tool.
