What Is An SSL/TLS Handshake? SSL/TLS are protocols used for encrypting information between two points. It is usually between server and client, but there are times when server to server and client to client encryption are needed. This article will focus only on the negotiation between server and client.

SSL, TLS, and STARTTLS refer to standard protocols used to secure email transmissions. SSL (Secure Sockets Layer) and its successor, Transport Layer Security (TLS), provide a way to encrypt a communication channel between two computers over the Internet. In most cases, the terms SSL and TLS can be used interchangeably unless you’re referring What is TLS & How Does it Work? | ISOC Internet Society However, SSL 3.0 is now considered insecure and was deprecated by RFC 7568 in June 2015, with the recommendation that TLS 1.2 should be used. TLS 1.3 is also currently (as of December 2015) under development and will drop support for less secure algorithms. It should be noted that TLS does not secure data on end systems. The Evolution of SSL and TLS | DigiCert Blog Oct 05, 2017 TLS and SSL - IBM Since TLS evolved from SSL, the two terms are used interchangeably throughout this book. When a specific TLS or SSL protocol version is intended, it will be specifically noted. On z/OS® there are two different TLS implementations. System SSL, a component of the Cryptographic Services element, provides a full set of TLS APIs for C and C++ programs.

The wolfSSL embedded SSL library is a lightweight, portable, C-language-based SSL/TLS library targeted at IoT, embedded, and RTOS environments primarily because of its size, speed, and feature set.

TLS is an improved version of SSL. It works in much the same way as the SSL, using encryption to protect the transfer of data and information. The two terms are often used interchangeably in the industry although SSL is still widely used. When you buy an 'SSL' certificate from DigiCert, you can of course use it with both SSL and TLS protocols. SSL vs TLS - What's the Difference?
