Ssl & Tls Essentials. Securing The Web Free 💯 Confirmed

When you visit a site with https:// , a process called the occurs in milliseconds:

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.

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). SSL & TLS Essentials. Securing the Web free

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

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: When you visit a site with https:// ,

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"

Developed by Netscape in the mid-90s, SSL was the original standard. However, due to various security vulnerabilities, it has been officially deprecated. One of the biggest hurdles to web security used to be cost

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.
