SSLTLSsalausta

SSLTLSsalausta refers to the encryption protocols Secure Sockets Layer (SSL) and Transport Layer Security (TLS). These protocols are foundational for secure communication over computer networks, most notably the internet. SSL was the original protocol, developed by Netscape, but it has largely been superseded by its successor, TLS. The primary function of SSL/TLS is to provide authentication and encryption between a client, such as a web browser, and a server, such as a website. This ensures that the data exchanged between them is private and cannot be intercepted or tampered with by unauthorized parties. When a user visits a website secured with SSL/TLS, their browser establishes a secure connection with the server. This process typically involves a "handshake" where the server presents a digital certificate to the client, verifying its identity. Once authenticated, a secure, encrypted channel is established, meaning all subsequent data transmission, like login credentials or payment information, is scrambled and unreadable to eavesdroppers. The "https" prefix in a website's URL and the padlock icon in the browser's address bar are common indicators that SSL/TLS encryption is active. While SSL is still sometimes referenced, modern secure connections almost exclusively use TLS, with current versions being TLS 1.2 and TLS 1.3.
