如果登录帐号及密码等个人数据是以未经加密的形态在网络上发送,那任何网络监听者都可以轻易地拦截和窃取此信息。因此,每当您尝试登录某个网站时,应当要先确认该网站是否有提供 HTTPS 加密连接,以确保您的个人数据安全。确认的方式非常简单,只需注意观察其网址的部分,若是以“https://”开头,则表示连接处于加密状态,但若开头为“http://”,则该连接上所传输的数据都未被加密。

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.
