Hypertext Transfer Protocol Secure – HTTPS and how it works Hypertext Transfer Protocol Secure, an extension of HTTP, is used to establish a secure connection over a computer network, and is extensively used on the Internet. The communication protocol here is an encrypted one, that is, the communication between the client and the server is secure and encrypted. This encryption is done by using Transport Layer Security. This protocol is therefore known as HTTP over TLS. What makes HTTPS a trusted protocol? Secure. Encrypted. Authentic. A user can access any website while the privacy and integrity of the exchanged data remains intact. It prevents man-in-the-middle attacks. It becomes highly necessary to make sure that the data exchanged between the client and the server is not tampered with. Without a secure connection, there is a risk of sensitive data leaking out. The bidirectional encryption of the communication ensures that such a situation is prevented. Earlier, HTTPS was used for online transactions and for sensitive emails and transactions in the corporate information systems. Since 2018, HTTPS has been widely used by web users to protect page authenticity on websites; secure accounts; and keep user identity and web browsing private. You might like to check your connection next time you use the internet. If the connection is not secure, you might look up for a secure webpage or connect to VPN for secure connections. How did HTTPS get its name? Netscape Communications, while working on their Netscape Navigator web browser created HTTPS in 1994. Earlier HTTPS was used along with SSL protocol. As SSL later became TLS, HTTPS was formally specified by RFC 2818 in May 2000. How to trust HTTPS websites? Look for these when you connect to a website: The browser software correctly implements HTTPS with pre-installed certificate authorities. The certificate authority vouches only for legitimate websites. The website provides a valid certificate. The certificate correctly identifies the website. The protocol’s encryption layer is secure against tampering. Now when HTTPS has been made easy for you, you might want to check it out for yourself. Browse safe and trust HTTPS.
