NAME

       tpm2_listpcrs -  display  all  PCR  values  in  given algorithm with -g, display given PCR
       values in given algorithms with -L, or if no algorithm is given, output all algs.   Output
       file  just  contains all returned PCR values in binary format and in 0~23 order and in the
       requested order if multiple algs were requested. Assume the  caller  know  the  pcr  value
       length corresponding to the given bank/algorithm.

SYNOPSIS

       tpm2_listpcrs[ COMMON OPTIONS ] [ TCTI OPTIONS ] [ --algorithim|--output|--selList|--algs|
       ]

       display all PCR values in given algorithm with -g,  display  given  PCR  values  in  given
       algorithms  with  -L,  or  if  no  algorithm  is given, output all algs.  Output file just
       contains all returned PCR values in binary format and in 0~23 order and in  the  requested
       order  if  multiple  algs  were  requested.  Assume  the  caller know the pcr value length
       corresponding to the given bank/algorithm.

DESCRIPTION

       tpm2_listpcrs display all PCR values in given algorithm with -g, display given PCR  values
       in  given  algorithms  with -L, or if no algorithm is given, output all algs.  Output file
       just contains all returned PCR values in binary format  and  in  0~23  order  and  in  the
       requested  order  if  multiple  algs  were requested. Assume the caller know the pcr value
       length corresponding to the given bank/algorithm.

       [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.

EXAMPLES

       tpm2_listpcrs
