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.

OPTIONS¶

-g ,--algorithim

The algorithm id, optional 0x0004 TPM_ALG_SHA1 0x000B TPM_ALG_SHA256 0x000C TPM_ALG_SHA384 0x000D TPM_ALG_SHA512 0x0012 TPM_ALG_SM3_256

-o ,--output

The file to hold the PCR values in binary format, optional

-L ,--selList

The list of pcr banks and selected PCRs' ids (0~23) for each bank

-s ,--algs

[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

display all PCR values:  
tpm2_listpcrs
display the PCR values with specified bank:
tpm2_listpcrs -g 0x04
display the PCR values with specified banks and store in a file:
tpm2_listpcrs -L 0x04:16,17,18+0x0b:16,17,18 -o pcrs
display the supported algs in the PCR banks:
tpm2_listpcrs -s
