class siotls.contents.handshakes.client_hello.ClientHello

Client Hello handshake as defined in RFC 8446 Section 4.1.2. Conveys the client’s supported cryptographic algorithms, along with additional extensions to negotiate optional features.

Note: this handshake, together with ServerHello, are the only two messages that are not encrypted.

__init__(random, cipher_suites, extensions)

Parameters:

• random (bytes)

• cipher_suites (list[CipherSuites | int])

• extensions (list[Extension])

cipher_suites: list[CipherSuites | int]

The list of ciphers that this client support.

See also cipher_suites.

extensions: dict[ExtensionType | int, Extension]

The extensions, indexed by siotls.iana.ExtensionType, that are used to negotiate cryptographic settings and all additionnal features for this connection.

msg_type: HandshakeType | HandshakeType_ = 1

The unique numeric identifier of the handshake.

random: bytes

32 bytes generated by a secure random number generator. Uniquely identify this connection.
