              provisioning server

       -S ,--EKserverAddr
              specifies to attempt retrieving the  Endorsement Credentials from the specified   TPM manufacturer
              provisioning server

       -U ,--SSL_NO_VERIFY
              specifies   to   attempt   connecting   with   the   TPM  manufacturer  provisioning  server  with

       -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.
