SSL & TLS Essentials: Securing the Web In the modern digital landscape, every click, login, and transaction relies on a silent handshake happening in the background. This handshake is governed by and its more advanced successor, TLS (Transport Layer Security) . Together, they form the backbone of web security, ensuring that data moving between a user’s browser and a server remains private and untampered. 1. What are SSL and TLS?

At their core, SSL and TLS are cryptographic protocols designed to provide communications security over a computer network.

It ensures that data cannot be modified or corrupted during transfer without being detected. 3. How the "Handshake" Works SSL & TLS Essentials. Securing the Web free

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.

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 In

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).

When you visit a site with https:// , a process called the occurs in milliseconds: It ensures that data cannot be modified or

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
