Transport Layer Security (TLS), and its now-deprecated predecessor, Secure Sockets Layer (SSL), are cryptographic protocols designed to provide communications security over a computer network.

SSL and TLS are both cryptographic protocols that provide authentication and data encryption between servers, machines, and applications operating over a network (e.g. a client connecting to a web server).

TLS maintains backward compatibility with SSL and therefore the communication protocol is nearly identical in any of the mentioned versions herein. The two important differences between SSL v.3...

What is SSL? SSL (Secure Sockets Layer) certificates are an integral part of website security. When you visit a website with SSL, the site's SSL certificate enables you to encrypt the data you send...

The SSL/TLS protocol encrypts internet traffic of all types, making secure internet communication (and therefore internet commerce) possible. Here are the basics of how it works and what comes next.

SSL refers to Secure Sockets Layer whereas TLS refers to Transport Layer Security. How similar both are? SSL and TLS are cryptographic protocols that authenticate data transfer between servers...

Obligatory SSL/TLS Handshake Graphic. Some confusion about how SSL/TLS handshakes work is due to the handshake being only the prelude to the actual, secured session itself.
