          [--peer_cap] is capability flags for the peer. It is used only when --exe_conn has VER_ONLY.
          [--basic_mut_auth] is the basic mutual authentication policy. BASIC is used in CHALLENGE_AUTH. By default, BASIC is used.
          [--mut_auth] is the mutual authentication policy. WO_ENCAP, W_ENCAP or DIGESTS is used in KEY_EXCHANGE_RSP. By default, W_ENCAP is used.
-         [--meas_sum] is the measurment summary hash type in CHALLENGE_AUTH, KEY_EXCHANGE_RSP and PSK_EXCHANGE_RSP. By default, ALL is used.
-         [--meas_op] is the measurement operation in GET_MEASUREMEMT. By default, ONE_BY_ONE is used.
-         [--meas_att] is the measurement attribute in GET_MEASUREMEMT. By default, HASH is used.

          [--key_upd] is the key update operation in KEY_UPDATE. By default, ALL is used. RSP will trigger encapsulated KEY_UPDATE.
          [--slot_id] is to select the peer slot ID in GET_MEASUREMENT, CHALLENGE_AUTH, KEY_EXCHANGE and FINISH. By default, 0 is used.
                  0xFF can be used to indicate provisioned certificate chain. No GET_CERTIFICATE is needed.
          [--slot_count] is to select the local slot count. By default, 3 is used. And the slot store cert chain continuously in emu.
          [--save_state] is to save the current negotiated state to a write-only file.

                  The responder should set CACHE capabilities, otherwise the state will not be saved.
                  The requester will clear PRESERVE_NEGOTIATED_STATE_CLEAR bit in END_SESSION to preserve, otherwise this bit is set.
                  The responder will save empty state, if the requester sets PRESERVE_NEGOTIATED_STATE_CLEAR bit in END_SESSION.
          [--load_state] is to load the negotiated state to current session from a read-only file.
                  The requester and responder will provision the state just after SPDM context is created.

          [--exe_mode] is used to control the execution mode. By default, it is SHUTDOWN.
                  SHUTDOWN means the requester asks the responder to stop.
                  CONTINUE means the requester asks the responder to preserve the current SPDM context.
          [--exe_conn] is used to control the SPDM connection. By default, it is DIGEST,CERT,CHAL,MEAS,MEL,GET_CSR,SET_CERT, GET_KEY_PAIR_INFO,SET_KEY_PAIR_INFO.
                  VER_ONLY means REQUESTER does not send GET_CAPABILITIES/NEGOTIATE_ALGORITHMS. It is used for quick symmetric authentication with PSK.
                      The version for responder must be provisioned from ver.

    Take spdm_requester_emu or spdm_responder_emu as an example, a user may use `spdm_requester_emu --pcap SpdmRequester.pcap > SpdmRequester.log` or `spdm_responder_emu --pcap SpdmResponder.pcap > SpdmResponder.log` to get the PCAP file and the log file.
