Types

type LegacyMultiMeasurements

type LegacyMultiMeasurements map[string]measurements.M

type MeasurementsContainer

type MeasurementsContainer struct {
	MeasurementID   string         `json:"measurement_id"`
	AttestationType string         `json:"attestation_type"`
	Measurements    measurements.M `json:"measurements"`
}

type MultiMeasurements

type MultiMeasurements struct {
	Measurements []MeasurementsContainer
}

MultiMeasurements holds several known measurements, and can check if given measurements match known ones.

func New

func New(path string) (m *MultiMeasurements, err error)

New returns a MultiMeasurements instance, with the measurements loaded from a file or URL.

func (*MultiMeasurements) Contains

func (m *MultiMeasurements) Contains(measurements map[uint32][]byte) (found bool, foundMeasurement *MeasurementsContainer)

Contains checks if the provided measurements match one of the known measurements. Any keys in the provided measurements which are not in the known measurements are ignored.
