OPTIONS

       -e ,--endorsePasswd
              specifies current endorse password (string,  optional, default:NULL).

       -o ,--ownerPasswd
              specifies current owner password (string,  optional, default:NULL).

       -P ,--ekPasswd
              specifies the EK password when created  (string, optional, default:NULL).

       [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: 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.
