Who needs nonces anyway? Every request is idempotent becaue every computation is deterministic. Exactly-once delivery 4 tha win

type Peer struct {
	Pk        PK
	Addresses []Address
	LastSeen  time.Time
}

func (Peer) Equals ¶

func (p Peer) Equals(p2 Peer) bool

type SK ¶

type SK [SKSize]byte

func DecodeSK ¶

func DecodeSK(key string) (bs SK, err error)

Takes a string representation of a secret key and returns the byte representation of it

type ThisPeer ¶

type ThisPeer struct {
	Peer
	Kp Keypair
}

func (ThisPeer) Encrypt ¶

func (p ThisPeer) Encrypt(msg []byte, to PK) (out []byte, err error)

chunks are chunked because not having to hold the whole thing in memory at the same time (?) we cold do larger chunks but messages larger than 64k will probably be rare (apart from file transfers? large responses? I'll get to tis when I do gateway implementation soon)
