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 pa‐
       rameters 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.
