An Overview of SSL:
The SSL full form is Secure Socket Layer, it is a protocol that is a widely used method for sending information securely across a network. By establishing a secure connection between a Web server and a browser, SSL technology, developed by Netscape, ensures confidential and secure data transmission. SSL uses the Transport Control Protocol for communication (TCP).
The mechanism of transferring data over a network between a client and a server is referred to as using a “socket” in SSL. A Web server needs an SSL certificate to create an encrypted Secure Socket Layer connection while using SSL for secure Internet transactions. A network connection component above the program layer called the transport layer is where SSL encrypts network connection segments.
A Web browser creates both a public and a private (secret) key as part of the asymmetric cryptographic process that is the foundation of SSL. A data file containing the public key is called a certificate signing request (CSR). The private key is only given to the recipient. Let us see the working principle of SSL in the upcoming points.
How does SSL Work?
SSL ensures a high level of security by encrypting data sent over the internet. Anyone trying to intercept this data will run into a confusing mix of characters that is almost impossible to decrypt. Between two communicating devices, SSL initiates an authentication procedure known as a handshake to verify that both devices are who they claim to be.
The SSL full form is Secure Socket Layer, in order to guarantee data integrity and that it has not been altered before reaching its intended recipient, SSL additionally digitally verifies data. Each iteration of SSL has been more secure than the previous one. SSL was replaced by TLS (Transport Layer Security) in 1999.
