HTTPSekniikka

HTTPSekniikka, also known as HTTPS, is a protocol for secure communication over a computer network, which is widely used on the Internet. It is the successor to the HTTP protocol and is designed to provide secure communication over a computer network, protecting the integrity and confidentiality of data between the user's computer and the site. HTTPS uses Transport Layer Security (TLS) or, formerly, its predecessor, Secure Sockets Layer (SSL), to encrypt communications. The use of HTTPS is therefore also known as HTTP Secure, or HTTP over TLS.

HTTPS is used to secure communications by providing two primary services: encryption and data integrity. Encryption ensures that data transmitted between the user and the site cannot be read by anyone other than the intended recipient. Data integrity ensures that the data has not been altered in transit, maintaining the accuracy and reliability of the transmitted information.

The implementation of HTTPS involves the use of an SSL/TLS certificate, which is issued by a trusted Certificate Authority (CA). This certificate verifies the identity of the website and enables the secure exchange of data. When a user accesses a website using HTTPS, their browser checks the SSL/TLS certificate to ensure that the connection is secure before allowing the user to proceed.

The adoption of HTTPS has become increasingly important in recent years due to the growing number of cyber threats and the need to protect sensitive information. Many websites now use HTTPS by default, and web browsers have started to mark sites that do not use HTTPS as "Not Secure" to alert users to potential risks. Additionally, search engines like Google have indicated that HTTPS is a ranking factor, meaning that websites using HTTPS may have an advantage in search engine results.

In summary, HTTPS is a crucial protocol for securing communications on the Internet. It provides encryption and data integrity, ensuring that data transmitted between users and websites remains confidential and accurate. The widespread adoption of HTTPS is essential for protecting sensitive information and mitigating cyber threats.
