Developed by Netscape in the mid-90s, SSL was the original standard. However, due to various security vulnerabilities, it has been officially deprecated.
Once the browser trusts the certificate, they work together to create a "session key." This is a unique, temporary key used to encrypt all data for that specific visit. 4. The Move to "HTTPS Everywhere"
When you visit a site with https:// , a process called the occurs in milliseconds: SSL & TLS Essentials. Securing the Web free
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).
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. Developed by Netscape in the mid-90s, SSL was
One of the biggest hurdles to web security used to be cost. However, the "Securing the Web Free" movement, led by initiatives like , has changed the game. Let’s Encrypt is a free, automated, and open Certificate Authority that allows anyone to secure their website at no cost. Most modern web hosts now offer "one-click" free SSL/TLS setup through these services. Conclusion
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
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?
