SSL is an encryption protocol used in the Internet. This protocol provides a secure connection between internet browsers and websites that allows Internet users to securely exchange their private data with other websites. The full form of SSL is Secure Sockets Layer.

In today’s time, almost all the websites are using SSL. SSL protocol is being used by crores of people doing online business so that they can protect their customers and the online transactions being done by them and by using it it will be impossible for the hacker to steal the customer’s data from the middle of that contact. .

Websites that use SSL have a domain name (eg with a picture of a locked lock attached to it, which is visible in the url of our Internet browser and https is written instead of http. With the domain name, it shows that the website is completely secure.

If a user clicks on the picture of the lock that appears in the address bar, then from there the website that the user is viewing shows the SSL certification, identification and all other information to the user. Every website has a unique SSL certificate.

SSL is also called TLS (Transport Layer Security) protocol. It can be used not only in the website but also in e-mail and everywhere else.

If a person is running an e-commerce site then it is very important for him to use SSL because in this site all his information is taken from the customer to make payment.

You must have known that what is SSL? So let’s know how does this work? SSL certificate uses two types of keys; One is the public key and the other is the private key.

Together these two keys make a secure connection through which the data is shared in a secure way.

When we want to know something about a subject or buy something, we write the name of a website in our web browser. After that the web browser connects with the server of that website which is using SSL protocol.

The user requests the server of that website from his browser to give his identity. After giving the request, the web server sends a copy of its SSL certificate along with a copy of it to a public key browser.

After that the user checks that certificate so that the user can decide whether he can trust it to share his private data with that website or not. After checking, when the user decides to trust him, then again he sends an encrypt message to his server.

The web server decrypts that encrypt message, after that it sends an acknowledgment to the browser that SSL encryption should be started with the user, after that the private data of the user is exchanged between the browser and the web server in a secure manner which is completely remains confidential.
