HTTPSliikennettä

HTTPSliikennettä refers to the secure transmission of data over the internet using the Hypertext Transfer Protocol Secure (HTTPS) protocol. HTTPS is an extension of the Hypertext Transfer Protocol (HTTP), which is the foundation of data communication for the World Wide Web. The primary difference between HTTP and HTTPS is the use of encryption for secure communication. HTTPS uses Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL), to encrypt the data transmitted between the user's browser and the website.

The use of HTTPS is crucial for protecting sensitive information such as login credentials, personal data, and financial information. By encrypting the data, HTTPS prevents eavesdropping, tampering, and message forgery, ensuring that the data remains confidential and integral during transmission.

Implementing HTTPS involves obtaining an SSL/TLS certificate from a trusted Certificate Authority (CA). This certificate is used to establish a secure connection between the user's browser and the website. Modern web browsers display a padlock icon in the address bar when a website is using HTTPS, indicating that the connection is secure.

The adoption of HTTPS has become increasingly important with the rise of cyber threats and the growing awareness of data privacy. Many websites now use HTTPS by default, and web browsers are increasingly penalizing websites that do not use HTTPS, such as by marking them as "Not Secure" or downgrading their search engine rankings. This trend underscores the importance of HTTPS in ensuring the security and privacy of internet communications.
