It ensures you are talking to the correct server. Through "certificates," your browser verifies that the website is who it claims to be, preventing "man-in-the-middle" attacks.
The browser and server exchange "Hello" messages to agree on which version of TLS they will use and which encryption algorithms (cipher suites) to employ. SSL & TLS Essentials. Securing the Web free
This is the modern, more secure version of SSL. While most people still use the term "SSL" colloquially, almost all modern "SSL certificates" actually use the TLS protocol (specifically TLS 1.2 or 1.3). 2. The Three Pillars of Web Security SSL/TLS provides three essential protections: It ensures you are talking to the correct server
Historically, SSL was reserved for checkout pages or login screens. Today, the industry standard is "HTTPS Everywhere." Search engines like Google now prioritize secure sites in rankings, and browsers like Chrome flag non-encrypted sites as "Not Secure." This shift has made the web safer for everyone, regardless of the sensitivity of the data being exchanged. 5. Obtaining Security for Free This is the modern, more secure version of SSL
The server sends its SSL/TLS certificate to the browser. This certificate contains the server’s public key and is signed by a trusted Certificate Authority (CA).
At their core, SSL and TLS are cryptographic protocols designed to provide communications security over a computer network.
It hides data from eavesdroppers. If a hacker intercepts the communication, they see a garbled mess of characters rather than your credit card number or password.
