What is HTTPS?
HTTPS – Stands for Hypertext Transfer Protocol Secure. It is a secured version of HTTP, which is used to define how data is formatted and transmitted across the web. HTTPS has an advantage over HTTP in that the data sent when fetching a webpage is encrypted, adding a layer of security so that third parties can’t gather data about the webpage when the data is sent from the server to the browser.
Hypertext Transfer Protocol Secure (HTTPS) is a variant of the standard web transfer protocol (HTTP) that adds a layer of security on the data in transit through a secure socket layer (SSL) or transport layer security (TLS) protocol connection.
HTTPS enables encrypted communication and a secure connection between a remote user and the primary web server. HTTPS uses an encryption protocol to encrypt communications. The protocol is called Transport Layer Security (TLS), although formerly it was known as Secure Sockets Layer (SSL). This protocol secures communications by using what’s known as an asymmetric public key infrastructure.
This type of security system uses two different keys to encrypt communications between two parties:
- The private key – this key is controlled by the owner of a website and it’s kept, as the reader may have speculated, private. This key lives on a web server and is used to decrypt information encrypted by the public key.
- The public key – this key is available to everyone who wants to interact with the server in a way that’s secure. Information that’s encrypted by the public key can only be decrypted by the private key.
Its primarily designed to provide enhanced security layer over the unsecured HTTP protocol for sensitive data and transactions such as billing details, credit card transactions and user login, etc. HTTPS encrypts every data packet in transition using SSL or TLS encryption techniques to avoid intermediary hackers and attackers to extract the content of the data, even if the connection is compromised.
The HTTPS is configured and supported by default in most web browsers and initiates a secure connection automatically if the accessed web servers’ requests secure connection. HTTPS works in collaboration with certificate authorities that evaluates the security certificate of the accessed website.
