Types ¶
type ChainKeyable ¶
type ChainKeyable interface {
Key() []byte
Index() uint32
NextKey() *chain.Key
MessageKeys() *message.Keys
Current() *chain.Key
}
ChainKeyable is an interface for all chain key implementations that are part of a session keypair.
type DerivedSecrets ¶
type DerivedSecrets struct {
// contains filtered or unexported fields
}
DerivedSecrets is a structure for holding the derived secrets for the Root and Chain keys for a session.
func NewDerivedSecrets ¶
func NewDerivedSecrets(keyMaterial []byte) *DerivedSecrets
NewDerivedSecrets returns a new RootKey/ChainKey pair from 64 bytes of key material generated by the key derivation function.
func (*DerivedSecrets) ChainKey ¶
func (d *DerivedSecrets) ChainKey() []byte
ChainKey returns the ChainKey bytes.
func (*DerivedSecrets) RootKey ¶
func (d *DerivedSecrets) RootKey() []byte
RootKey returns the RootKey bytes.
type KeyPair ¶
type KeyPair struct {
RootKey RootKeyable
ChainKey ChainKeyable
}
KeyPair is a session key pair that holds a single root and chain key pair. These keys are ratcheted after every message sent and every message round trip.
func NewKeyPair ¶
func NewKeyPair(rootKey RootKeyable, chainKey ChainKeyable) *KeyPair
NewKeyPair returns a new session key pair that holds a root and chain key.
type RootKeyable ¶
type RootKeyable interface {
Bytes() []byte
CreateChain(theirRatchetKey ecc.ECPublicKeyable, ourRatchetKey *ecc.ECKeyPair) (*KeyPair, error)
}
RootKeyable is an interface for all root key implementations that are part of a session keypair.
