Types

type HmacKeyManager

type HmacKeyManager struct{}

HmacKeyManager generates new HmacKeys and produces new instances of Hmac.

func NewHmacKeyManager

func NewHmacKeyManager() *HmacKeyManager

NewHmacKeyManager returns a new HmacKeyManager.

func (*HmacKeyManager) DoesSupport

func (_ *HmacKeyManager) DoesSupport(typeUrl string) bool

DoesSupport checks whether this KeyManager supports the given key type.

func (*HmacKeyManager) GetKeyType

func (_ *HmacKeyManager) GetKeyType() string

GetKeyType returns the type URL of keys managed by this KeyManager.

func (*HmacKeyManager) GetPrimitiveFromKey

func (km *HmacKeyManager) GetPrimitiveFromKey(m proto.Message) (interface{}, error)

GetPrimitiveFromKey constructs a HMAC instance for the given HmacKey.

func (*HmacKeyManager) GetPrimitiveFromSerializedKey

func (km *HmacKeyManager) GetPrimitiveFromSerializedKey(serializedKey []byte) (interface{}, error)

GetPrimitiveFromSerializedKey constructs a Hmac instance for the given serialized HmacKey.

func (*HmacKeyManager) NewKeyData

func (km *HmacKeyManager) NewKeyData(serializedKeyFormat []byte) (*tinkpb.KeyData, error)

NewKeyData generates a new KeyData according to specification in the given serialized HmacKeyFormat. This should be used solely by the key management API.

func (*HmacKeyManager) NewKeyFromKeyFormat

func (km *HmacKeyManager) NewKeyFromKeyFormat(m proto.Message) (proto.Message, error)

NewKeyFromKeyFormat generates a new HmacKey according to specification in the given HmacKeyFormat.

func (*HmacKeyManager) NewKeyFromSerializedKeyFormat

func (km *HmacKeyManager) NewKeyFromSerializedKeyFormat(serializedKeyFormat []byte) (proto.Message, error)

NewKeyFromSerializedKeyFormat generates a new HmacKey according to specification in the given serialized HmacKeyFormat.
