NAME

       tpm2_dump_capability - Display TPM capabilities in a human readable form.

SYNOPSIS

       tpm2_dump_capability [ COMMON OPTIONS ] [ TCTI OPTIONS ] [ --c|--capability]=capability_type

DESCRIPTION

       Query  the  TPM  for it's capabilities / properties and dump them to the console.  This is a thin wrapper
       around the GetCapability command.

OPTIONS

       [-c|--capability] - The name of the capability group to query.
              Currently supported capability groups are:
                “properties-fixed” - Display fixed TPM properties.
                “properties-variable” - Display variable TPM properties.
                “algorithms” - Display data about supported algorithms.
                “commands” - Display data about supported commands.

       [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.
