Functions

func NewETMReader

func NewETMReader(r io.Reader, s cipher.Stream, mac HMAC) msgio.ReadCloser

NewETMReader Encrypt-Then-MAC

func NewETMWriter

func NewETMWriter(w io.Writer, s cipher.Stream, mac HMAC) msgio.WriteCloser

NewETMWriter Encrypt-Then-MAC

Types

type HMAC

type HMAC struct {
	hash.Hash
	// contains filtered or unexported fields
}

type Session

type Session interface {
	// ReadWriter returns the encrypted communication channel
	ReadWriter() msgio.ReadWriteCloser

	// LocalPeer retrieves the local peer.
	LocalPeer() peer.ID

	// LocalPrivateKey retrieves the local private key
	LocalPrivateKey() ci.PrivKey

	// RemotePeer retrieves the remote peer.
	RemotePeer() peer.ID

	// RemotePublicKey retrieves the remote's public key
	// which was received during the handshake.
	RemotePublicKey() ci.PubKey

	// Close closes the secure session
	Close() error
}

type SessionGenerator

type SessionGenerator struct {
	LocalID    peer.ID
	PrivateKey ci.PrivKey
}

SessionGenerator constructs secure communication sessions for a peer.

func (*SessionGenerator) NewSession

func (sg *SessionGenerator) NewSession(ctx context.Context,
	insecure io.ReadWriter) (Session, error)

NewSession takes an insecure io.ReadWriter, performs a TLS-like handshake with the other side, and returns a secure session. See the source for the protocol details and security implementation. The provided Context is only needed for the duration of this function.
