NAME

       stpm-verify - Verify data using the TPM chip

SYNOPSIS

       stpm-verify [ -hq ] -f data -s sig file -k <key file>

DESCRIPTION

       stpm-verify verifies data signed by stpm-sign.

       This  program is mostly made for debugging, to make sure that the TPM is set up correctly and a valid key
       was generated.

OPTIONS

       -h     Show usage info.

       -f data file
              File containing data to be verified.

       -s sig file
              File containing signature from stpm-sign.

       -k key file
              File containing the encrypted key blob.

EXAMPLES

       dd if=/dev/urandom of=to-sign bs=1 count=35
       stpm-sign -k ~/.simple-tpm-pk11/my.key -f to-sign -r > to-sign.sig
       stpm-verify -f to-sign -k ~/.simple-tpm-pk11/my.key -s to-sign.sig

DIAGNOSTICS

       Most errors will probably be related to interacting with the TPM chip.  Resetting the TPM chip and taking
       ownership should take care of most of them. See the TPM-TROUBLESHOOTING section of simple-tpm-pk11(7).
