  • What is TLS? What’s the Difference Between TLS and SSL?
  • Transport Layer Security (TLS) or Transport Layer Security is a layer of security that ensures that data between two communications applications is encrypted in a secure way. TLS, which for the first time in 1999, uses an asymmetric encryption algorithm for authentication. TLS is also considered to be a more advanced and secure version of the Secure Sockets Layer (SSL) protocol, a different security layer developed by Netscape.


  • TLS is used to securely transfer data between applications communicating with each other. Even if you are aware, you may be using TLS in different formats every day on the internet. TLS is widely used in secure internet site connections, instant messaging softwares, file transfers, various softwares, internet applications, VPN connections and even VOIP connections, which place serious importance on safety.


  • What’s the Difference Between TLS and SSL?
  • Both SSL and TSL are essentially encryption and authorization protocols. With these protocols, data transfer from the server to the server or securely from the server to the client is performed. SSL is more primitive than TSL. TSL has emerged as a result of many years of development in the world of IT and the internet, which I can accept as a newer version of SSL.


  • SSL was first published by Netscape in 1995 as SSL 2.0. The first version of SSL, the SSL 1.0 protocol, was never made available to all users. SSL 2.0, which had been used for some time in the market, broke out very soon and appeared to have serious security vulnerabilities. Soon after, in 1996, SSL 2.0 was replaced by the newer version of SSL 3.0.






  • By the year 1999, TLS usage was presented as a stronger encryption layer. The inadequacy of a kind SSL caused TLS 1.0 to be born. We can say that TLS is a more secure protocol, although there are not big structural differences between them. Especially when it comes to message authorization and key material production, it assumes the role of being a safer layer in terms of TLS algorithm.


  • Should you opt for SSL or TLS?
  • In SSL 2.0 and 3.0 versions, different security vulnerabilities have been explored since the 90’s. Moreover, some of them have recently been confirmed by IEFT in 2011 and 2015. Many of these exploits are no longer available, but scenarios that have been made seem to imply that SSL is not as reliable as it should be.


  • Internet browsers that also need to handle security vulnerabilities have started to warn users by labeling internet sites that use old SSL certificates as unsafe. If we consider all these disadvantages, TLS is more advantageous in many respects. To switch to TLS, you first need to disable SSL 2.0 and SSL 3.0 from your server settings.
