			TPM Management - tpm_sealdata

NAME
       tpm_sealdata - seal input data to the system's TPM

SYNOPSIS
       tpm_sealdata [OPTION]

DESCRIPTION
       tpm_sealdata seals sensitive input data to the SRK of the system's TPM
       and optionally a PCR configuration.  Backup your data, it is
       unrecoverable from this format if the SRK changes or the specified PCR
       configuration is unreproducable.	 The result can be unsealed by
       functions in libtpm_unseal, such as tpmUnsealFile(3).

       -h, --help
	      Display command usage info.

       -v, --version
	      Display command version info.

       -l, --log [none|error|info|debug]

       -i, --infile FILE

       -o, --outfile FILE
	      Output file.  Default is STDOUT.

       -p, --pcr NUMBER
	      Seal data to the current value of the specified pcr. This option
	      can be given NUM_PCRS times.  The specified pcr is in the range
	      of 0 to NUM_PCRS-1. NUM_PCRS is at least 16 but may vary by
	      platform.

       -z, --well-known
	      Use TSS_WELL_KNOWN_SECRET (20 zero bytes) as the SRK password.
	      You will not be prompted for the SRK password with this option.

       -u, --unicode
	      Use TSS UNICODE encoding for the SRK password to comply with
	      applications using TSS popup boxes.
