NAME

       tss2_quote(1) -

SYNOPSIS

       tss2_quote [OPTIONS]

SEE ALSO

       fapi-config(5)  to  adjust Fapi parameters like the used cryptographic profile and TCTI or
       directories for the Fapi metadata storages.

       fapi-profile(5) to determine the cryptographic algorithms and parameters for all keys  and
       operations  of  a  specific  TPM  interaction like the name hash algorithm, the asymmetric
       signature algorithm, scheme and parameters and PCR bank selection.

DESCRIPTION

       tss2_quote(1) - This command performs an attestation using the TPM.  The PCR bank for each
       provided  PCR  index  and  signing scheme are set in the cryptographic profile (cf., fapi-
       profile(5)).

OPTIONS

       These are the available options:

       • -x, --pcrList=STRING:

         An array holding the PCR indices to quote against.

       • -Q, --qualifyingData=FILENAME or - (for stdin):

         A nonce provided  by  the  caller  to  ensure  freshness  of  the  signature.   Optional
         parameter.

       • -l, --pcrLog=FILENAME or - (for stdout):

         Returns the PCR log for the chosen PCR.  Optional parameter.

         PCR  event  logs  are  a  list  (arbitrary  length  JSON  array) of log entries with the
         following content.

                - recnum: Unique record number
                - pcr: PCR index
                - digest: The digests
                - type: The type of event. At the moment the only possible value is: "LINUX_IMA" (legacy IMA)
                - eventDigest: Digest of the event; e.g. the digest of the measured file
                - eventName: Name of the event; e.g. the name of the measured file.

       • -f, --force:

         Force overwriting the output file.

       • -p, --keyPath=STRING:

         Identifies the signing key.

       • -q, --quoteInfo=FILENAME or - (for stdout):

         Returns a JSON-encoded structure holding  the  inputs  to  the  quote  operation.   This
         includes the digest value and PCR values.

       • -o, --signature=FILENAME or - (for stdout):

         Returns the signature over the quoted material.

       • -c, --certificate=FILENAME or - (for stdout):

         The certificate associated with keyPath in PEM format.  Optional parameter.

COMMON OPTIONS

       This  collection  of  options are common to all tss2 programs and provide information that
       many users may expect.

       • -h, --help [man|no-man]: Display the tools manpage.  By default, it attempts  to  invoke
         the  manpager  for the tool, however, on failure will output a short tool summary.  This
         is the same behavior if the “man” option argument  is  specified,  however  if  explicit
         “man”  is  requested,  the tool will provide errors from man on stderr.  If the “no-man”
         option if specified, or the manpager fails, the short options will be output to stdout.

         To successfully use the manpages feature requires the manpages to  be  installed  or  on
         MANPATH, See man(1) for more details.

       • -v, --version: Display version information for this tool, supported tctis and exit.

EXAMPLE

              tss2_quote --keyPath=HS/SRK/quotekey --pcrList="10,16" --qualifyingData=qualifyingData.file --signature=signature.file --pcrLog=pcrLog.file --certificate=certificate.file --quoteInfo=quoteInfo.info

RETURNS

       0 on success or 1 on failure.
