Secure Socket Layer (SSL) and Transport Layer Security (TLS) are cryptographic protocols designed to provide secure communication over a computer network. Both of these protocols provide data privacy, integrity, and authentication between a client and server. However, TLS is an updated and more secure version of SSL. In this section, we will discuss the differences between SSL and TLS, and why TLS should be preferred over SSL.

SSL (Secure Socket Layer)

SSL was originally developed by Netscape in the mid-1990s to secure transactions over the internet. There have been three versions of SSL:

TLS (Transport Layer Security)

TLS was introduced by the Internet Engineering Task Force (IETF) in 1999 as a replacement for SSL. TLS can be considered as the new version of SSL with improved security features. The TLS protocol has gone through several updates:

Key Differences between SSL and TLS


Given the security concerns with SSL and the outdated encryption methods it uses, it is essential to use TLS for secure communication. It is recommended to use the latest version of TLS (currently, 1.3) for maximum security and performance.

In conclusion, make sure to configure your systems and applications to use TLS and disable SSL to ensure secure communication and protection against known vulnerabilities.
