Both SSL and TLS are cryptographic protocols between networked servers, computers, and devices for authentication and data encryption. SSL is 25 years old. Netscape developed the first version of SSL (version 1.0) in 1995, but it was not released because of its critical security vulnerabilities. SSL 2.0 was not good, and SSL 3.0 was published just over a year later. Unanimous development, people participated in it and developed TLS 1.0. TLS 1.0 is very similar to SSL 3.0, but there is enough difference to reduce it to SSL 3.0 in advance.

In this topic, we will discuss the difference between the SSL and TLS. But firstly, we need to know the SSL and TLS.

What is SSL?

Secure Socket Layer (SSL) is the most used internet security cryptographic protocol before the Transport Layer Security (TLS) was released in 1990. However, the SSL protocol has been discontinued, but the TLS has now adopted it. Most people call it SSL. SSL provides a secure link between two devices or computers linked to the internet or the internal network.

What is TLS?

TLS is a popular security protocol designed for Internet communication to enhance privacy and data security. It is generally used to encrypt communication among web packages and servers, including a web browser loading page. It can be used for encrypting different voice messages for texts and IP. It was introduced by the Internet Technology Task Force (IETF) of the International Standards Organization (ISO), which launched the primary protocol in 1999. In 2018, the latest version was released and contained TLS 1.3.

Main Differences between the SSL and TLS

Here, we are going to discuss the main differences between the SSL and TLS.

  1. The SSL is a secure socket layer, whereas the TSL is a Transportation Layer Protection.
  2. The SSL and TLS cryptographic protocols authenticate server-to-device data transfers. For example, a cryptographic protocol encrypts data exchanged among the Web server and a user.
  3. A secure framework is needed to encrypt the data from both sides. An SSL/TLS certificate supports this. It serves as an encryption portal for encrypting information that prevents unauthorized entry by hackers.
  4. For SSL message authentication, key information and configuration data are needed on an ad hoc basis, even as the TLS model depends on the authentication code for the HMAC hash.
  5. SSL was a first-kind cryptographic protocol. On the other hand, TLS was the latest modified SSL version.

Head to Head Comparison of SSL and TLS

Here, we are going to discuss head to head comparison of SSL and TLS in tabular form:

For Fortezza, SSL supports the Cipher Suite. The encryption of Fortezza doesn't support TLS.
It makes use of the Message Authentication (MAC) code for the record protocol. It makes use of Hashed MAC for the Record Protocol.
The SSL uses the pre-master secret message digest for the generation of master secrets. It is a slightly different way of defining master confidentiality in the TLS.
Verify the complex in the SSL Certificate. In the TLS, Sample Certificate Verification.
Included in the SSL alert message is "no certificate". It removes the summary of the alarm and adds a dozen other values.
SSL message authentication offers ad-hoc key information and client data. The TLS version is based on the HMAC Hash Message's authentication code.


TLS and SSL are protocols that provide an overview of data transmission authentication and encryption over the Internet. However, SSL stays the dominant internet term, as all public variations of SSL are non-exclusive and were deprecated for a long time. We need to install it in a certificate at the server to apply each SSL and TLS protocols. It is called "SSL certificates" by most people, and both SSL and TLS protocols support these certificates.
