Recognizing secure websites relies on encryption and identity verification signals shown in the browser. When a site uses HTTPS, data between your browser and the server is encrypted, which helps protect information from eavesdroppers and tampering. A valid certificate from a trusted authority confirms the site’s identity, and the domain listed on the certificate should match the site you’re visiting, so you’re not being redirected to a fake page. The padlock icon is a user-visible cue that the connection is encrypted and the certificate has been validated. Together, these cues indicate a secure website. The other options fail to guarantee security: HTTP sends data in plaintext, which can be intercepted; FTP with insecure login exposes usernames and passwords; and having a query string doesn’t by itself indicate the connection is encrypted or that the site’s identity has been verified.
