HTTPSprotokollassa

HTTPSprotokollassa, short for Hypertext Transfer Protocol Secure, is the secure version of HTTP, the protocol used for transferring data over the World Wide Web. It encrypts the communication between a user's web browser and the website they are visiting. This encryption ensures that any sensitive information, such as login credentials, credit card numbers, or personal details, exchanged between the two parties cannot be intercepted and read by unauthorized individuals.

The security of HTTPS is achieved through the use of Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL). These cryptographic protocols establish an encrypted connection by using digital certificates. When a browser connects to an HTTPS website, it first verifies the website's digital certificate. This certificate, issued by a trusted Certificate Authority (CA), confirms the identity of the website and ensures that the connection is not being redirected to a malicious site.

Once the certificate is verified, an encrypted tunnel is created between the browser and the server. All data transmitted through this tunnel is scrambled, making it unintelligible to anyone who might try to eavesdrop on the connection. Websites that use HTTPS typically display a padlock icon in the browser's address bar, indicating a secure connection. This is crucial for building trust with users and protecting their privacy online.
