The digital certificate includes the following: It coordinates with a reputable CA, such as Comodo SSL or DigiCert to get an SSL certificate for its website. Brand A decides to use SSL on its website. Let's say that a company, Brand A, wants to launch a secure website where users can safely order its products without putting themselves at risk of having their information stolen. The purpose of the SSL certificate is to confirm to the user and the web browser they're using that they are interacting with the desired web server and not an imposter. The SSL protocol process starts with a company acquiring a valid SSL certificate from a trusted certificate authority ( CA). The 's' indicates to the visitor that the site uses SSL or TLS to secure its user activity. Most websites today display the prefix HTTPS at the beginning of their web address. This is why HTTP over SSL ( HTTPS), also known as HTTP Secure, has emerged as HTTP's more secure successor. Malicious actors can easily read or extract names, addresses, credit card numbers and other personally identifiable information sent to a website. HTTP uses public networks and lacks encryption, making it vulnerable. SSL became a key part of internet security because of problems with Hypertext Transfer Protocol ( HTTP), the framework used to connect web clients to web servers. By making the protocol accessible to its competitors, Netscape expanded its share of the web server market and also ensured the SSL protocol would become an IETF proposed standard.

The web server software company then published the protocol and made it available for other companies to implement. Netscape initially launched SSL as a proprietary protocol. Part of SSL's significance lies in the fact that it was the first widely used and broadly implemented network protocol to enable cryptographically secured communications between client and server systems. It is just one of the ways in which public key infrastructure ( PKI) is used by modern businesses. SSL can scramble clear text entered on a website using asymmetric cryptography and public key encryption. SSL uses public key and private key encryption and other cryptographic functions to secure connections between devices communicating over a TCP/IP network.

Without SSL, data sent to and from a website could be intercepted by a threat actor. It facilitated safe transactions between consumers and businesses, helping create the foundation for e-commerce. SSL typically involved securing connections between a web browser (client) and a website (server). In addition to securing internet connections, SSL was also used to authenticate and encrypt other applications at the network transport layer. While SSL is still in use today, mostly in legacy systems, TLS has taken over its role in securing internet connections. It was replaced by the Transport Layer Security ( TLS) protocol. SSL suffered from numerous problems, and the Internet Engineering Task Force ( IETF) stopped recommending its use in 2015. It eventually came to be used to secure authentication and encryption for other applications at the network transport layer. Netscape formally introduced the SSL protocol in 1995, making it the first widely used protocol for securing online transactions between consumers and businesses. Secure sockets layer (SSL) is a networking protocol designed for securing connections between web clients and web servers over an insecure network, such as the internet.
