 NAME
      tpmtool - GnuTLS TPM tool

 SYNOPSIS
      tpmtool [-flag [value]]... [--opt-name[[=| ]value]]...

      All arguments must be options.

 DESCRIPTION
      Program that allows handling cryptographic data from the TPM chip.

 OPTIONS
      -d number, --debug=number
           Enable debugging.  This option takes an integer number as its
           argument.  The value of number is constrained to being:
               in the range  0 through 9999

           Specifies the debug level.

      --infile=file
           Input file.


      --outfile=string
           Output file.


      --generate-rsa
           Generate an RSA private-public key pair.

           Generates an RSA private-public key pair in the TPM chip. The key
           may be stored in filesystem and protected by a PIN, or stored
           (registered) in the TPM chip flash.

      --register
           Any generated key will be registered in the TPM.  This option
           must appear in combination with the following options: generate-
           rsa.


      --signing
           Any generated key will be a signing key.  This option must appear
           in combination with the following options: generate-rsa.  This
           option must not appear in combination with any of the following
           options: legacy.


      --legacy
           Any generated key will be a legacy key.  This option must appear

           in combination with the following options: generate-rsa.  This
           option must not appear in combination with any of the following
           options: signing.


      --user
           Any registered key will be a user key.  This option must appear
           in combination with the following options: register.  This option
           must not appear in combination with any of the following options:
           system.

           The generated key will be stored in a user specific persistent
           storage.

      --system
           Any registred key will be a system key.  This option must appear
           in combination with the following options: register.  This option
           must not appear in combination with any of the following options:
           user.

           The generated key will be stored in system persistent storage.

      --pubkey=url
           Prints the public key of the provided key.


      --list
           Lists all stored keys in the TPM.


      --delete=url
           Delete the key identified by the given URL (UUID)..


      --sec-param=security parameter
           Specify the security level [low, legacy, normal, high, ultra]..

           This is alternative to the bits option. Note however that the
           values allowed by the TPM chip are quantized and given values may
           be rounded up.

      --bits=number
           Specify the number of bits for key generate.  This option takes
           an integer number as its argument.


      --inder, --no-inder
           Use the DER format for keys..  The no-inder form will disable the
           option.

           The input files will be assumed to be in the portable DER format
           of TPM. The default format is a custom format used by various TPM
           tools

      --outder, --no-outder
           Use DER format for output keys.  The no-outder form will disable
           the option.

           The output will be in the TPM portable DER format.

      -h, --help
           Display usage information and exit.

      -!, --more-help
           Pass the extended usage information through a pager.

      -v [{v|c|n}], --version[={v|c|n}]
           Output version of program and exit.  The default mode is `v', a
           simple version.  The `c' mode will print copyright information
           and `n' will print the full copyright notice.

 EXAMPLES
      To generate a key that is to be stored in filesystem use:
          $ tpmtool --generate-rsa --bits 2048 --outfile tpmkey.pem

      To generate a key that is to be stored in TPM's flash use:
          $ tpmtool --generate-rsa --bits 2048 --register --user

      To get the public key of a TPM key use:
          $ tpmtool --pubkey tpmkey:uuid=58ad734b-bde6-45c7-89d8-756a55ad1891;storage=user           --outfile pubkey.pem

      or if the key is stored in the filesystem:
          $ tpmtool --pubkey tpmkey:file=tmpkey.pem --outfile pubkey.pem

      To list all keys stored in TPM use:
          $ tpmtool --list

 EXIT STATUS
      One of the following exit values will be returned:

      0 (EXIT_SUCCESS)
           Successful program execution.

      1 (EXIT_FAILURE)
           The operation failed or the command syntax was not valid.

      70 (EX_SOFTWARE)
           libopts had an internal operational error.  Please report it to
           autogen-users@lists.sourceforge.net.  Thank you.
