SSL Full Form
What is the full form of SSL?
A networking protocol called Secure Sockets Layer (SSL) is used for secure communications between web clients and web servers over insecure networks like the internet. The SSL protocol was first widely used for protecting online transactions between customers and businesses in 1995 when Netscape formally announced it. The client can verify the identity of the server thanks to this protocol. Here the server is a powerful and centralized computer hardware and software and the clients are the various other systems that send their data to the centralized system(server). An updated and more secure version of SSL is TLS(Transport Layer Security).
Working of SSL
SSL encrypts data that is sent across the web in order to offer a high level of privacy. As a result, anyone attempting to intercept this data will only be able to make out a jumbled collection of characters that is incredibly difficult to decrypt.
In order to make sure that both communicating devices are indeed who they say they are, SSL starts an authentication procedure between them known as a handshake.
In order to provide data integrity and ensure that the data has not been tampered with before reaching its intended receiver, SSL additionally digitally signs data.
SSL Certification
Only websites that have an SSL certificate can use SSL (technically a "TLS certificate"). An SSL certificate serves as a badge or identification card that verifies a person is who they claim to be. The server hosting a website or application stores and displays SSL certificates on the Internet. The website's public key is one of the most crucial pieces of data in an SSL certificate. Encryption and authentication are made feasible via the public key. The public key is viewed by a user's device, which uses it to create safe encryption keys with the web server.
Importance of SSL
Data on the Web used to be sent in plaintext, which meant that anyone could read it if they intercepted the message. For instance, if a customer went to a shopping website, made a purchase, and entered their credit card information, that information would be transmitted across the Internet in clear view. SSL was developed to address this issue and safeguard user privacy. SSL makes sure that anyone who intercepts the data can only see a jumbled mess of characters by encrypting any data that travels between a user and a web server. The credit card number submitted by the customer is now secure and only accessible by the purchasing website.

SSL, which is typically regarded as a component of the Presentation layer, is located between the Application layer and the Transport layer.
SSL guarantees the privacy of all data sent between a client and a server.
The communication between a web browser and a web server is protected using SSL. This converts the URL of a website from HTTP to HTTPS, where the "S" indicates "secure."
A piece of code on your web server called an SSL certificate offers security for online conversations. The SSL certificate makes it possible for a web browser to establish an encrypted connection with your secured website.
