What does HTTPS signify about a website?

HTTPS, which stands for Hypertext Transfer Protocol Secure, signifies that a website employs encryption to secure data transmitted between the user's browser and the web server. This encryption is accomplished through protocols such as SSL (Secure Socket Layer) or TLS (Transport Layer Security). The use of HTTPS is crucial for protecting sensitive information like passwords, credit card details, and personal data from interception and eavesdropping while in transit over the internet.

In the context of online security, HTTPS not only ensures data privacy but also instills trust among users. When a website is secured with HTTPS, browsers typically display a padlock icon in the address bar, indicating that the connection is safe and encrypted. This can enhance user confidence, particularly on sites that handle sensitive transactions.

The other options do not accurately reflect the purpose of HTTPS. A website being outdated or having a government endorsement does not have a direct correlation with whether it uses HTTPS or not. Likewise, informative websites can also implement HTTPS to ensure data privacy and security.
