Ef persónulegar upplýsingar á borð við lykilorð fyrir innskráningu fara ódulrituð yfir internetið, er mjög auðvelt að hlera þær. Ef þú ert að skrá þig inn á eitthvað vefsvæði, ættirðu að ganga úr skugga um að vefsvæðið bjóði HTTPS-dulritun, sem verndar gegn þessari tegun hlerana. Þú getur sannreynt þetta á staðsetningastikunni: ef tengingin þín er dulrituð, byrjar slóðin með “https://” í stað bara “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.
