Types

type UserDialTokens

type UserDialTokens struct {
	FromUsername string
	Tokens       []*[32]byte
}

type Wheel

type Wheel struct {
	// contains filtered or unexported fields
}

func (*Wheel) EraseKeys

func (w *Wheel) EraseKeys(round uint32)

func (*Wheel) Exists

func (w *Wheel) Exists(username string) bool

Exists returns true if username is in the keywheel and false otherwise.

func (*Wheel) IncomingDialTokens

func (w *Wheel) IncomingDialTokens(myUsername string, round uint32, numIntents int) []*UserDialTokens

func (*Wheel) MarshalBinary

func (w *Wheel) MarshalBinary() ([]byte, error)

func (*Wheel) OutgoingDialToken

func (w *Wheel) OutgoingDialToken(username string, round uint32, intent int) *[32]byte

func (*Wheel) Put

func (w *Wheel) Put(username string, round uint32, secret *[32]byte)

func (*Wheel) Remove

func (w *Wheel) Remove(username string)

func (*Wheel) SessionKey

func (w *Wheel) SessionKey(username string, round uint32) *[32]byte

func (*Wheel) UnmarshalBinary

func (w *Wheel) UnmarshalBinary(data []byte) error

func (*Wheel) UnsafeGet

func (w *Wheel) UnsafeGet(username string) (round uint32, secret *[32]byte)

UnsafeGet returns the internal keywheel state for a username. This is unsafe; use SessionKey, if possible.
