    // NegotiateFlags (4 bytes): In connectionless mode, a NEGOTIATE structure that contains a set of flags (section 2.2.2.5) and represents the conclusion of negotiation—the choices the client has made from the options the server offered in the CHALLENGE_MESSAGE.

    // Version (8 bytes): A VERSION structure (section 2.2.2.10) that SHOULD be populated only when the NTLMSSP_NEGOTIATE_VERSION flag is set in the NegotiateFlags field; otherwise, it MUST be set to all zero. This structure is used for debugging purposes only. In normal protocol messages, it is ignored and does not affect the NTLM message processing.

    // This is not transmitted on the wire; it is retained so callers (e.g. SMB message
    // signing) can use it as the MAC key. When no key exchange is negotiated it equals
    // the NTLMv2 SessionBaseKey. It is nil for the NTLMv1 path.
