However, Netscape has developed SSL protocols. SSL has mainly three protocol versions SSL 1.0, SSL 2.0 and SSL 3.0 and all are deprecated. Both protocols are widely used in most email, application, VoIP. In the world of cryptography, there are mainly SSL (Secure Socket Layer) and TLS (Transport Layer Security) protocols. It would become hard to intercept the encrypted data for attackers thus the data remains confidential between two endpoints.
Data confidentiality: Data confidentiality prevents data from being exposed to third party or attackers. The message/data is confirmed through Message authentication code. Because of strong encryption, the network attacker cannot damage or change the content between the user and the web server. Data integrity: SSL ensures data integrity, It means the data is not altered during the transition. Moreover, the browser upon visiting SSL secured site shows a green padlock to ensure visitors that the website is safe for online deals. The data of a server certificate includes domain name and company’s information. Authentication: In SSL, a user visits a website meanwhile the server sends a copy of a certificate to the user’s browser to make it known that the browser is connecting to the right website. Every SSL/TLS certificate as per new NIST and CA/browser guideline are having a modern and robust algorithm to make the online environment safe. Encryption not only is a goal of SSL certificate but also provides authentication of business identity, data privacy and easy exchange of information. SSL certificates has its inherent features that make SSL stand out in the industry. This article is designed to encourage website owners in implementing SSL on their website and make aware of few terms that are used in SSL. 
Some websites have been ignoring the use of SSL/TLS, as it is not in the interest of customers. It is true that in modern cybercrime age if you ignore web security, it could put your business in the drastic situation resulting in loss of money and business reputation. Still many people know little about SSL and its core practices.
SSL/TLS certificate has turned out a worth considering solution for web security.
