SYNOPSIS

11       tpm_sealdata [OPTION]
12
13

DESCRIPTION

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

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