Functions

func ParseLocality 

func ParseLocality(eventData []byte) (uint8, error)

ParseLocality parses TPM locality from EV_NO_ACTION event corresponding to the TPM initialization.

Types

type Digest 

type Digest struct {
	HashAlgo TPMAlgorithm
	Digest   []byte
}

Digest is the digest reported by an Event.

type ErrInvalidDigestLength 

type ErrInvalidDigestLength struct {
	Expected int
	Received int
}

ErrInvalidDigestLength means an event has a digest of a size not appropriate for a selected hash algorithm.

func (ErrInvalidDigestLength) Error 

func (err ErrInvalidDigestLength) Error() string

Error implements interface `error`.

type ErrLocality 

type ErrLocality struct {
	EventData []byte
}

ErrLocality means it was unable to detect the locality to initialize the PCR0 value.

func (ErrLocality) Error 

func (err ErrLocality) Error() string

Error implements interface `error`.

type ErrNotSupportedHashAlgo 

type ErrNotSupportedHashAlgo struct {
	TPMAlgo TPMAlgorithm
}

ErrNotSupportedHashAlgo means selected hash algorithm is not supported (yet?)

func (ErrNotSupportedHashAlgo) Error 

func (err ErrNotSupportedHashAlgo) Error() string

Error implements interface `error`.

type ErrParse 

type ErrParse struct {
	Err error
}

ErrParse means unable to read from the io.Reader

func (ErrParse) Error 

func (err ErrParse) Error() string

Error implements interface `error`.

func (ErrParse) Unwrap 

func (err ErrParse) Unwrap() error

Unwrap implements `xerrors.Wrapper`.

type ErrRead 

type ErrRead struct {
	Err error
}

ErrRead means unable to read from the io.Reader

func (ErrRead) Error 

func (err ErrRead) Error() string

Error implements interface `error`.

func (ErrRead) Unwrap 

func (err ErrRead) Unwrap() error

Unwrap implements `xerrors.Wrapper`.

type Event 

type Event struct {
	PCRIndex pcr.ID
	Type     EventType
	Data     []byte
	Digest   *Digest
}

Event is a single entry of a parsed EventLog.

type EventType 

type EventType uint32

EventType defines the kind of data reported by an Event.

type TPMAlgorithm 

type TPMAlgorithm = tpm2.Algorithm

TPMAlgorithm is an identified of a TPM-supported hash algorithm.

type TPMEventLog 

type TPMEventLog struct {
	Events []*Event
}

TPMEventLog is a parsed EventLog.

func Parse 

func Parse(input io.Reader) (*TPMEventLog, error)

Parse parses a binary EventLog.

func (*TPMEventLog) FilterEvents 

func (eventLog *TPMEventLog) FilterEvents(pcrIndex pcr.ID, hashAlgo TPMAlgorithm) ([]*Event, error)

FilterEvents returns only the events which has a specified PCR index and a digest of a specified hash algorithm.
