What is SSL certificate and how does it work?

Are you wondering what an SSL certificate is and why you need one, well, In this article, you will learn what is SSL certificate and how it works.

SSL certificates are security essential to the World Wide Web. They benefit both website owners and internet surfers.

Consumers can feel safe shopping online or accessing private information without the worry of having their credentials stolen by hackers over a wireless network.

Website owners enjoy the added protection from hackers as well as a boost in credibility with consumers more aware of cyber theft these days.

An SSL certificate is a form of digital identification that allows secure connections between websites and browsers,

encrypting communications sent across networks such as WiFi hotspots or cellular data networks.

The SSL technology is now recommended worldwide by all major web browsers,

including Google Chrome, Microsoft Internet Explorer, Mozilla Firefox, Apple Safari, Opera browser and others.

It was previously known as Secure Sockets Layer but has now evolved into Transport Layer Security or TSL.

The SSL technology is a means of security for data sent from a browser to a web server.

It establishes an encrypted link between them,

which in turn ensures that all data sent remains private and under the sole control of the website owner controlling the webserver.

It also verifies that website owners are who they claim to be.

All websites using SSL have a digital certificate that proves their identity when sending secure messages.  

Due to recent Google changes, SSL certificates will become essential in ranking well on Google within the next year.

There is speculation as to exactly what score will be required for this change,

however, it is certain that currently, SSL certificates do not directly affect rankings at all but because of the new changes, they soon will.

Websites that currently have SSL certificates and those that do not will be on the same playing field once these changes come into effect,

so website owners should begin to take this matter seriously.

SSL certificates also add an extra layer of security that prevents e-commerce fraud such as credit card theft or identity theft.

The encrypted link makes it extremely difficult for hackers to intercept data being sent between the web server and browser because,

without the SSL technology, all data is sent in plain text using a numerical code system which can very easily be intercepted by electronic eavesdroppers.

Without SSL certificates, any online business transactions are impossible to ensure true privacy during transmission.

SSL certificates give website owners an opportunity to improve consumer confidence and increase business.

With SSL certificates it is easier to gain trust, which means more sales and greater revenue.

This has quickly become an expectation of all consumers especially after Google announced they would be requiring SSL certificates on all websites within the next year.

To summarize, an SSL certificate is a digital verification that confirms encrypting data sent between visitors using the internet and the webserver are safe.

It enhances consumer confidence which leads to an increase in revenue for website owners.

All major web browsers require SSL technology or risk not being used by internet users worldwide.

Internet surfers can feel safe shopping online or accessing private information on unsecured networks.

SSL certificates will soon affect Google rankings as well. SSL certificates are the future of internet security and web browsing.

Millions of sensitive information are transmitted by internet users on a daily basis ranging from bank statements to security numbers.

To avoid the interception and manipulation of this data by third parties, the SSL certificate was adopted.
