	RWC     io.ReadWriteCloser
}

TPM interfaces with a TPM device on the system.

func NewTPM ¶

func NewTPM() (*TPM, error)

NewTPM looks for a TPM and initializes it for further use

func (*TPM) Close ¶

GetCapability requests the TPMs capability function and returns an interface. User needs to take care of the data for now.

func (*TPM) GetVersion ¶

func (t *TPM) GetVersion() TPMVersion

GetVersion returns the TPM version

func (*TPM) Info ¶

func (t *TPM) Info() (*TPMInfo, error)

Info returns information about the TPM.

func (*TPM) MeasurementLog ¶

func (t *TPM) MeasurementLog() ([]byte, error)

MeasurementLog reads the TCPA eventlog in binary format from the Linux kernel

func (*TPM) NVReadValue ¶

func (t *TPM) NVReadValue(index uint32, ownerPassword string, size, offhandle uint32) ([]byte, error)

NVReadValue reads a value from a given NVRAM index Type and byte order for TPM1.2 interface: (offset uint32) Type and byte oder for TPM2.0 interface: (authhandle uint32)

type TPMInfo ¶

type TPMInfo struct {
	Version      TPMVersion
	Interface    TPMInterface
	VendorInfo   string
	Manufacturer TCGVendorID

	// FirmwareVersionMajor and FirmwareVersionMinor describe
	// the firmware version of the TPM, but are only available
	// for TPM 2.0 devices.
