var EncryptConnections = true

EncryptConnections is a global parameter because it should either be enabled or _completely disabled_. I.e. a node should only be able to talk to proper (encrypted) networks if it is encrypting all its transports. Running a node with disabled transport encryption is useful to debug the protocols, achieve implementation interop, or for private networks which -- for whatever reason -- _must_ run unencrypted.

Functions

func ID

func ID(c Conn) string

ID returns the ID of a given Conn.

func String

func String(c Conn, typ string) string

String returns the user-friendly String representation of a conn

Types

type Conn

type Conn interface {
	smux.Conn

	// ID is an identifier unique to this connection.
	ID() string

	LocalAddr() net.Addr
	RemoteAddr() net.Addr

	Transport() tpt.Transport

	// LocalPeer (this side) ID, PrivateKey, and Address
	LocalPeer() peer.ID
	LocalPrivateKey() ic.PrivKey
	LocalMultiaddr() ma.Multiaddr

	// RemotePeer ID, PublicKey, and Address
	RemotePeer() peer.ID
	RemotePublicKey() ic.PubKey
	RemoteMultiaddr() ma.Multiaddr
}

Conn is a generic multi-stream message-based Peer-to-Peer connection. It contains the PeerConn interface (unfortunately Go still doesn't allow duplicate interface methods...)

type Listener

type Listener interface {

	// Accept waits for and returns the next connection to the listener.
	Accept() (Conn, error)

	// Addr is the local address
	Addr() net.Addr

	// Multiaddr is the local multiaddr address
	Multiaddr() ma.Multiaddr

	// LocalPeer is the identity of the local Peer.
	LocalPeer() peer.ID

	SetAddrFilters(*filter.Filters)

	// Close closes the listener.
	// Any blocked Accept operations will be unblocked and return errors.
	Close() error
}

Listener is an object that can accept connections. It matches net.Listener

type PeerConn

type PeerConn interface {
	io.Closer

	// LocalPeer (this side) ID, PrivateKey, and Address
	LocalPeer() peer.ID
	LocalPrivateKey() ic.PrivKey
	LocalMultiaddr() ma.Multiaddr

	// RemotePeer ID, PublicKey, and Address
	RemotePeer() peer.ID
	RemotePublicKey() ic.PubKey
	RemoteMultiaddr() ma.Multiaddr
}
