Tls handshake schnell sicher

Introduction

TLS is a cryptographic protocol used to encrypt data transfer between communication partners. It is located in the application layer of the Internet Protocol Suite (IP Suite) or in the presentation layer of the OSI model. It is typically use as a wrapper for other (insecure) protocols like HTTP or SMTP. Besides encryption TLS could be used for identification purposes of both communication partners. There are several versions of TLS with versions below 1.2 being deprecated. The current versions 1.2 and 1.3 dropped support of unsecure hash functions like MD5 or SHA224. An unconfigured v1.3 connection defaults to the cipher suite AES256_GCM_SHA384.
