SSL & TLS, Both security protocols are different from each other. In this article, we are going to compare both in detail. Let’s dive into it!

1. Differences to Know
Between SSL & TLS
Certificates
Have you ever wondered what the difference is between TLS and
SSL? or Are they just the same thing with different names?
Both TLS and SSL are cryptographic protocols that authenticate
data transfer between servers, systems, applications, and users.
But they still have differences. Just like a cappuccino is different
from Espresso, they may come from the same coffee bean, but
there are differences we must respect.
Their work is similar; they both encrypt the data exchanged
between a web server and a user, but they are still different from
each other on many levels.
SSL was a first-of-its-kind cryptographic protocol, whereas TLS is
relatively new and more of an upgraded version of SSL.

2. We need SSL/TLS certificates to ensure security from
Cybercrimes, which have become a very common threat on the
internet. The risk of data theft is the highest when its exchanged
through client and server systems. SSL/TLS certificates tackle
this issue by ensuring a secure exchange.
Let’s learn more about SSL and TLS certificates.
What is SSL?
SSL was first developed by Netscape in the year 1994; its main
function was to ensure secure communication between client and
server systems on the web. Eventually, it was standardized by
IETF (the Internet Engineering Task Force) as a protocol. Since
then, two versions of SSL have been rolled out by Netscape,
which fixed the flaws of the first version. Currently, SSL 3.0 is in
use.
SSL is a cryptographic protocol that uses explicit connections to
establish secure communication between a web server and a
client.

What is TLS?
TLS stands for Transport Layer Security. It is a successor to SSL
3.0 and was first released in 1999 by the Internet Engineering
Task Force. TSL v1.1 was released in 2008; it added protection
against CBC (Cipher Block chaining) attacks. TSL v1.0 and TLS
v1.1 were deprecated by Google, Apple, Microsoft, and Mozilla in
2020.
TLS v1.2 was rolled out in 2008. It included some additional
features. The latest version of TLS was released in August 2018.
It has major features which differentiate it from and makes it
better than its previous versions.
It is also a cryptographic protocol. It provides secure
communication between the web server and the client through
implicit connections. It is the successor of the SSL protocol.

SSL TLS
SSL stands for “Secure Socket Layer”.
TLS stands for “Transport Layer
Security”.
The first version was developed by
Netscape in 1995.
The First version was developed by the
IETF in 1999.
There are 3 versions of SSL that have
been released till today. SSL v1.0,
SSL v2.0, SSL v3.0.
There are 4 versions of TLS that have
been released till today. TLS v1.0, TLS
v1.1, TLS v1.2, TLS v1.3.
When it comes to algorithms, SSL
supports the Fortezza algorithm.
TLS does not support the Fortezza
algorithm.
In SSL, the message digest is used
for creating a master secret.
In TLS, a Pseudo-random function is
used for creating a master secret.
The Message Authentication Code
Protocol is used in SSL.
The Hashed Message Authentication
Code Protocol is used in TLS.
SSL is more complex than TLS. TLS is simple.
SSL is less secure compared to TLS. TLS provides high security.
SSL is less reliable and slower.
TLS is highly reliable and
faster because it is upgraded and
provides less latency.
SSL has been depreciated. TLS is still widely used.
SSL uses a port to set up an explicit
connection.
TLS uses a protocol to set up an
implicit connection.
