HTTPS

Hypertext Transfer Protocol (Secure)

HTTPS is an extension of the standard HTTP (Hypertext Transfer Protocol) used for transmitting data between a user’s web browser and a website. The key difference between HTTP and HTTPS is the added layer of security provided by HTTPS. Here’s how HTTPS works:

1. Encryption: HTTPS uses encryption protocols, such as SSL (Secure Sockets Layer) or its successor, TLS (Transport Layer Security), to encrypt the data exchanged between the user’s browser and the web server. This encryption ensures that even if someone intercepts the data, they won’t be able to read it without the decryption key.
2. Authentication: HTTPS also involves a process of authentication. It verifies the website’s identity to ensure the user connects to the legitimate and intended website. This is done through digital certificates issued by trusted Certificate Authorities (CAs).
3. Data Integrity: HTTPS ensures data integrity, meaning that the data exchanged between the user and the website remains unchanged during transit. Any tampering or modification of the data is detected and rejected.
4. Secure Communication: By using HTTPS, sensitive information such as login credentials, personal data, and payment information can be safely transmitted over the internet. It protects against eavesdropping and man-in-the-middle attacks.

HTTPS is a secure version of HTTP, providing encryption, authentication, and data integrity, making it the preferred choice for websites that handle sensitive information or require user logins. It is identified by a padlock symbol in the browser’s address bar and the https:// prefix in the website’s URL.
