tss2_unseal(1)		     General Commands Manual		  tss2_unseal(1)

NAME
     tss2_unseal(1) -

SYNOPSIS
     tss2_unseal [OPTIONS]

SEE ALSO
     fapi-config(5)  to  adjust Fapi parameters like the used cryptographic pro-
     file 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_unseal(1) - This command unseals data from a seal in the FAPI metadata
     store.   The  used decryption scheme is specified in the cryptographic pro-
     file (cf., fapi-profile(5)).

OPTIONS
     These are the available options:

     * -f, --force:

       Force overwriting the output file.

     * -p, --path=STRING:

       Path of the object for which the blobs will be returned.

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

       The decrypted data after unsealing.  Optional parameter.

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

     * -h,  --help  [man|no-man]: Display the tools manpage.  By default, it at-
       tempts to invoke the manpager for the tool, however, on failure will out-
       put 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 speci-
       fied, or the manpager fails, the short options will be output to stdout.

       To successfully use the manpages feature requires the manpages to be  in-
       stalled or on MANPATH, See man(1) for more details.

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

EXAMPLE
	    tss2_unseal --path=HS/SRK/myRSACrypt --data=data.file

RETURNS
     0 on success or 1 on failure.
