tss2_nvread(1)              General Commands Manual             tss2_nvread(1)

NAME
       tss2_nvread(1) -

SYNOPSIS
       tss2_nvread [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_nvread(1) - This command reads the entire data from an NV index of
       the TPM.

OPTIONS
       These are the availabe options:

       o -f, --force:

         Force overwriting the output file.

       o -o, --data=FILENAME or - (for stdout):

         Returns the value read from the NV space.

       o -p, --nvPath=STRING:

         Identifies the NV space to read.

       o -l, --logData=FILENAME or - (for stdout):

         Returns the JSON encoded log, if the NV index is of type "extend" and
         an empty string otherwise.  Optional parameter.

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

       o -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.

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

EXAMPLE

              tss2_nvread --nvPath=/nv/Owner/myNV --data=data.file


RETURNS
       0 on success or 1 on failure.
