Developed by Netscape in the mid-90s, SSL was the original standard. However, due to various security vulnerabilities, it has been officially deprecated.
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).
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. SSL & TLS Essentials. Securing the Web free
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.
It ensures that data cannot be modified or corrupted during transfer without being detected. 3. How the "Handshake" Works Developed by Netscape in the mid-90s, SSL was
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"
At their core, SSL and TLS are cryptographic protocols designed to provide communications security over a computer network. This certificate contains the server’s public key and
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:
