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 (km *HmacKeyManager) DoesSupport(typeURL string) bool
DoesSupport checks whether this KeyManager supports the given key type.
func (*HmacKeyManager) GetKeyType ¶
func (km *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 ¶
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.
