tpmtool - GnuTLS TPM tool
tpmtool [-flags] [-flag [value]] [--option-name[[=| ]value]]
All arguments must be options.
Program that allows handling cryptographic data from the TPM chip.
-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 file system 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 registered 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)..
--test-sign=url
Tests the signature operation of the provided object.
It can be used to test the correct operation of the signature
operation. This operation will sign and verify the signed
data.
--sec-param=security parameter
Specify the security level [low, legacy, medium, 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.
To generate a key that is to be stored in file system 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 file system:
$ tpmtool --pubkey tpmkey:file=tmpkey.pem --outfile pubkey.pem
To list all keys stored in TPM use:
$ tpmtool --list
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.
