TLStransportkryptering

TLStransportkryptering, often referred to as TLS encryption, is a standard security technology that creates an encrypted link between a server and a client, typically a web server and a web browser. This encrypted link ensures that all data transmitted between the server and the client remains private and integral. It is the successor to SSL (Secure Sockets Layer) and is widely used to protect sensitive information such as credit card numbers, usernames, and passwords.

The process begins with a handshake between the client and the server. During this handshake, they agree on the encryption algorithms to be used and exchange cryptographic keys. Once the handshake is complete, a secure, encrypted connection is established. Any data sent over this connection is then scrambled, making it unreadable to anyone who might intercept it. This protection is indicated to users by a padlock icon in their browser's address bar and the "https://" prefix in the website's URL.

TLS is crucial for maintaining trust and security on the internet. It prevents man-in-the-middle attacks, where an attacker could eavesdrop on or modify communications. Without TLStransportkryptering, online transactions and the exchange of personal data would be highly vulnerable. The latest versions of TLS offer enhanced security features and improved performance, making it an essential component of modern web security.
