NAME

       tpm2_send_command - Send a command to the TPM using the specified TCTI.

SYNOPSIS

       tpm2_send_command [COMMON OPTIONS ] [TCTI OPTIONS ]

DESCRIPTION

       tpm2_send_command  is  a  command  line  tool  used  to send a TPM command to the TPM. The
       command is read from stdin as a binary stream and transmitted to the TPM  using  the  TCTI
       specified  by  the caller. The response received from the TPM is written to stdout. Likely
       the caller will want to redirect this to a file or into a program to  decode  and  display
       the response in a human readable form.

OPTIONS

       [COMMON OPTIONS ]
              This collection of options are common to many programs and provide information that

              Display a manual describing the tool and its usage.

       -v, --version
              Display version information for this tool.

       -V, --verbose
              Increase the information that the tool prints to the console during its execution.

       [TCTI OPTIONS ]
              This collection of options are used to configure the varous TCTI modules available.

       -T, --tcti
              Select the TCTI used for communication with the next component down the TSS  stack.
              In  most  configurations this will be the TPM but it could be a simulator or proxy.
              Supported TCTIs are or “device” or “socket” .

       -d, --device-file
              Specify the TPM device file for use by the device TCTI. The default is /dev/tpm0.

       -R, --socket-address
              Specify the domain name or IP address used by  the  socket  TCTI.  The  default  is
              127.0.0.1.

       -p, --socket-port
              Specify the port number used by the socket TCTI. The default is 2321.

ENVIRONMENT

       ENVIRONMENT: TCTI
              This  collection  of environment variables that may be used to configure the varous
              TCTI  modules  available.   The  values  passed  through  these  variables  can  be
              overridden on a per-command basis using the available command line options.

       TPM2TOOLS_TCTI_NAME
              Select  the TCTI used for communication with the next component down the TSS stack.
              In most configurations this will be the TPM but it could be a simulator  or  proxy.
              See 'OPTIONS' section for the names of supported TCTIs.

       TPM2TOOLS_DEVICE_FILE
              Specify the TPM device file for use by the device TCTI.

       TPM2TOOLS_SOCKET_ADDRESS
              Specify the domain name or IP address used by the socket TCTI.

       TPM2TOOLS_SOCKET_PORT
              Specify the port number used by the socket TCTI.

EXAMPLES

       Assuming that the caller has a binary TPM command buffer in a file named tpm2_send_command
       may be used to send this to the TPM simulator using the following command:

              tpm2_send_command --tcti=device < tpm2-command.bin > tpm2-response.bin
