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).

       -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
