NAME

       tss2_gettpmblobs(1) -

SYNOPSIS

       tss2_gettpmblobs [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 pa‐
       rameters and PCR bank selection.

DESCRIPTION

       tss2_gettpmblobs(1) - This command returns the public and private blobs of  an  object,  such  that  they
       could  be loaded by a low-level API (e.g. ESAPI).  It also returns the policy associated with these blobs
       in JSON format.

OPTIONS

       These are the available options:

       • -f, --force:

         Force overwriting the output file.

       • -p, --path=STRING:

         The path of the object for which the blobs will be returned.

       • -u, --tpm2bPublic=FILENAME or - (for stdout):

         The returned public area of the object as a marshalled TPM2B_PUBLIC.  Optional parameter.

       • -r, --tpm2bPrivate=FILENAME or - (for stdout):

         The returned private area of the object as a marshalled TPM2B_PRIVATE.  Optional parameter.

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

         The returned policy associated with the object, encoded in JSON.  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_gettpmblobs --path=HS/SRK/myRSACrypt --tpm2bPublic=tpm2bPublic.file --tpm2bPrivate=tpm2bPrivate.file --policy=policy.file

RETURNS

       0 on success or 1 on failure.
