Tor evita que els que espien sàpiguen quins llocs visiteu. Tanmateix, la informació enviada sense xifrar a Internet mitjançant HTTP simple encara pot ser interceptada pels operadors de repetidors de sortida o qualsevol persona que observi el trànsit entre el repetidor de sortida i el lloc web de destinació. Si el lloc que esteu visitant utilitza HTTPS, el trànsit que surt del relleu de sortida es xifrarà i no serà visible per als espies.

This visualization shows what information is visible to eavesdroppers with and without Tor Browser and HTTPS encryption.

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.
