What is SSL?
The full form of SSL is Secure Sockets Layer, SSL is an encryption protocol used on the Internet. This protocol provides a secure connection between internet browsers and websites that allows Internet users to exchange their private data securely with other websites. In today’s time, almost all websites are using SSL. Millions of online business people are using the SSL protocol so that they can protect their customers and the online transactions they are doing and using it would be impossible for the hacker to steal the customer’s data from that contact.
Websites that use SSL have a domain name (eg www.technicalindiacg.com) attached to it with a picture of a locked lock that appears in our Internet browser URL and is written HTTPS instead of HTTP With the domain name, it shows that the website is completely secure. If a user clicks on the lock picture 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 of the website to the user. Every website has a unique SSL certificate.
With SSL: https://websitename.com
Without SSL: http://websitename.com
SSL is also known as TLS (Transport Layer Security) protocol. It can be used not only on websites but also in e-mail and in all other places. If a person is running an e-commerce site, then it is very important to use SSL because all their information is taken to make the payment from the customer on this site.
How does SSL work
You must have known what is SSL kya hai (What is)? So let’s know how it works? The SSL certificate uses two types of keys; One is a Public key and the other is a Private key. Together these two keys form a secure connection through which data is shared securely.
When we have to know something about a subject or have to buy something, we write the name of a website in our web browser. After that, the web browser connects with the server of the website which is using SSL protocol. The user requests the server of that website from his browser to give his identity. After requesting, the webserver sends a copy of its SSL certificate to a public key browser. After that, the user checks the certificate so that the user can decide whether he can trust him to share his private data with that website. After checking, when the user decides to trust him, he again sends an encrypted message to his server.
The web server decrypts that encrypt a message, after which it sends an acknowledgment to the browser that SSL encryption is started with the user, after that the user’s private data is exchanged between the browser and the web server securely which is complete remains confidential.
