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 parameters 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.
