Moin, dieser Standard dient nur dazu zu prüfen, ob ein TLS Handshake theoretisch möglich wäre, simuliert somit also einen normalen Handshake ohne jegliche Sicherheitsspezifikationen.

"TLS_NULL_WITH_NULL_NULL (TLS 1.1) is used to check if TLS connections are possible, and to simulate a handshake. It can also be used to switch cipher suites, and indicates the start of a new TLS connection. IIRC it is not used much and will been removed later by TLS 1.3 draft."
