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 many users may
              expect.

       -h, --help
              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
