What is HTTPS (HTTP Secure)?
Turkish: HTTPS
HTTPS encrypts HTTP traffic with TLS, providing confidentiality, integrity, and server identity between user, browser, and server.
What Is HTTPS?
HTTPS (HTTP Secure) is HTTP protected by TLS. When a user connects to a site, the browser checks the server certificate, establishes an encrypted connection, and sends data through that protected channel.
This protection has three main goals. Confidentiality prevents intermediaries from reading form data, session cookies, payment details, or other content. Integrity verifies that data was not modified in transit. Authentication helps confirm that the user is talking to a server authorized for the requested domain.
How HTTPS Works
HTTPS requires a valid TLS certificate for the domain. The certificate is signed by a trusted certificate authority and is valid for a defined period. During connection setup, client and server agree on supported cryptographic parameters; application data then travels in encrypted form.
Business Use
Login forms, payment pages, admin panels, API integrations, and customer portals should not be considered safe without HTTPS. Browser “not secure” warnings can reduce trust and conversion, and many modern browser features work only in secure contexts.
HTTPS does not solve every security problem by itself. Certificate renewal, correct redirects, HSTS, secure cookie settings, and SSL/TLS configuration need to be managed together.
