TLSÜbertragung

TLSÜbertragung, also known as TLS Transmission, refers to the process of securely transmitting data over a computer network using the Transport Layer Security (TLS) protocol. TLS is a cryptographic protocol designed to provide communications security over a computer network. It is the most widely deployed security protocol and is used by millions of websites and applications to protect sensitive information.

The primary goal of TLSÜbertragung is to ensure the confidentiality, integrity, and authenticity of data exchanged between two communicating applications, typically a client (like a web browser) and a server (like a web server). Confidentiality is achieved through encryption, which scrambles the data so that only the intended recipient can read it. Integrity is maintained by ensuring that the data has not been tampered with during transmission. Authenticity is verified by confirming the identity of the communicating parties, usually through digital certificates.

During a TLSÜbertragung, a handshake process occurs first. This handshake involves the client and server agreeing on the encryption algorithms to be used, exchanging cryptographic keys, and authenticating each other. Once the handshake is complete, the established TLS connection is used to encrypt and decrypt all subsequent data exchanged between the two parties. This secure tunnel protects against eavesdropping and man-in-the-middle attacks. Common applications of TLSÜbertragung include secure web browsing (HTTPS), secure email transmission (SMTPS, IMAPS, POP3S), and secure file transfers (FTPS).
