NAME

       tss2_gettpm2object(1)

SYNOPSIS

       tss2_gettpm2object [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_gettpm2object(1) - With this command for FAPI objects context files which can be used
       by   tpm2  tool  commands  can  be  created.   For  persistent  object  only  the  textual
       representation of the handle number as hex number will be written and for keys a tpm2 tool
       context  file  will  be  written.   If  the default TCTI differs from the FAPI profile the
       default the tcti can be  defined  with  the  -T  (–tcti)  option.   Note  To  avoid  wrong
       nv_written state in keystore before writing data to the NV ram with tpm2_nvwrite, at least
       an empty string should be written with tss2_nvwrite.

OPTIONS

       These are the available options:

       • -f, --force:

         Force overwriting the output file.

       • -p, --path=STRING:

         Path of the object for which the application data will be loaded.

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

         The returned key context or handle.

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.

EXAMPLES

              tss2_gettpm2object --path=/HS/SRK/myRSACrypt --key-context=mykey.ctx

              tss2_gettpm2object --path=/nv/Owner/mynv -c-
       The command can be used in options of tpm2 commands:

              handle=$(tss2_gettpm2object --path=/nv/Owner/mynv -c-)
              tpm2_nvread $handle

RETURNS

       0 on success or 1 on failure.
