TLSSSLkättely

TLSSSLkättely, a term often encountered in discussions surrounding internet security, refers to the process by which Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), establish a secure connection between a client and a server. This handshake is a crucial step in ensuring that data transmitted over the internet remains private and integral.

The TLSSSLkättely begins when a client, such as a web browser, initiates a connection to a server. The client sends a "hello" message, indicating its TLS/SSL capabilities and the cipher suites it supports. The server then responds with its own "hello" message, choosing a cipher suite from the client's list that it also supports and sending its digital certificate. This certificate contains the server's public key, which the client uses to verify the server's identity.

Following this, the client generates a session key, encrypts it using the server's public key, and sends it to the server. Only the server, with its corresponding private key, can decrypt this session key. Both the client and server then use this shared session key to encrypt and decrypt all subsequent communication during that session. This ensures that even if the data is intercepted, it remains unreadable to unauthorized parties. The entire TLSSSLkättely process is designed to be swift and largely invisible to the end-user, forming the foundation for secure online transactions and communication.
