what is HTTPS?

HTTPS stands for Hyper Text Transfer Protocol Secure, is a way to encrypt a channel over Internet to provide secure and encrypted communication, while sharing and accessing some personal information, like assessing a bank, social media page or providing your credit card, CVV in online shopping and transactions. HTTPS can be identified by a green padlock symbol in a browser’s URL bar. HTTPS means you can trust an organization because it has SSL certificate.

HTTPS is a successor protocol of HTTP which stands for Hyper Text Transfer Protocol, whereas HTTPS stands for Hyper Text Transfer Protocol Secure. HTTPS ensure user’s security by providing an isolated and encrypted channel for data or information transfer. HTTPS uses SSL and TLS encryption methods to encrypt data which uses asymmetric key encryption technique. In HTTP data is send with URL in plain text, which can be read or break by a hacker easily, whereas HTTPS encrypt data so that if a hacker break it he will not be able to read your secret information.

how does it work?

When a user request for a secured web page from HTTPS server the SSL certificate is transferred to user’s browser to ensure the user that server is genuine. An SSL handshake is done between user’s machine and the server, thereafter a secure and encrypted channel generates to communicate securely. When you are able to see pad lock green means SSL certificate has extended life, in case it is red or crossed means it has been expired and need to re audit. In expire case please do not provide your personal details like credit card numbers , CVV or any sort of passwords. So first of all make sure before submitting your personal information or credentials to a web portal, by checking green padlock symbol.
