Which list identifies the information that the client sends to the server in the negotiation phase of the TLS handshake?
Click on the arrows to vote for the correct answer
A. B. C. D.C.
During the Transport Layer Security (TLS) handshake process, the client and server exchange information to establish a secure connection. The negotiation phase of the TLS handshake begins with the client sending a ClientHello message to the server. The ClientHello message contains information about the client's supported TLS version, cipher-suites, and suggested compression methods.
Out of the options provided, option C (ClientHello, TLS versions it supports, cipher-suites it supports, and suggested compression methods) is the correct answer. The following is a detailed explanation of each option:
A. ClientStart, ClientKeyExchange, cipher-suites it supports, and suggested compression methods This option is incorrect because there is no such thing as a "ClientStart" message in the TLS handshake process. Additionally, the ClientKeyExchange message is sent during the key exchange phase of the TLS handshake, not the negotiation phase.
B. ClientStart, TLS versions it supports, cipher-suites it supports, and suggested compression methods Similar to option A, this option is incorrect because there is no "ClientStart" message in the TLS handshake process.
C. ClientHello, TLS versions it supports, cipher-suites it supports, and suggested compression methods This option is the correct answer. The ClientHello message is the first message sent by the client during the TLS handshake process. It contains information about the client's supported TLS version, cipher-suites, and suggested compression methods.
D. ClientHello, ClientKeyExchange, cipher-suites it supports, and suggested compression methods This option is incorrect because the ClientKeyExchange message is not sent during the negotiation phase of the TLS handshake process. It is sent during the key exchange phase.
