NAME

tss2_unseal(1) -

SYNOPSIS

tss2_unseal [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_unseal(1) - This command unseals data from a seal in the FAPI metadata store. The used decryption scheme is specified in the cryptographic profile (cf., fapi-profile(5)).

OPTIONS

These are the available options:

•

-f, --force:

•

-p, --path=STRING:

•

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

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.

•

-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.
