Types

type SecureSession

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

SecureSession is a lightweight mechanism for securing any kind of network communication (both private and public networks, including the Internet). It is protocol-agnostic and operates on the 5th layer of the network OSI model (the session layer).

func New

func New(id []byte, signKey *keys.PrivateKey, callbacks SessionCallbacks) (*SecureSession, error)

New makes a new Secure Session with provided peer ID, private key, and callbacks.

func (*SecureSession) Close

func (ss *SecureSession) Close() error

Close destroys a Secure Session.

func (*SecureSession) ConnectRequest

func (ss *SecureSession) ConnectRequest() ([]byte, error)

ConnectRequest generates a connection request that must be sent to the remote peer.

func (*SecureSession) GetRemoteID

func (ss *SecureSession) GetRemoteID() ([]byte, error)

GetRemoteID returns ID of the remote peer.

func (*SecureSession) GetRemoteId deprecated

func (ss *SecureSession) GetRemoteId() ([]byte, error)

GetRemoteId returns ID of the remote peer.

Deprecated: Since 0.11. Use GetRemoteID() instead.

func (*SecureSession) GetState

func (ss *SecureSession) GetState() int

GetState returns current state of Secure Session.

func (*SecureSession) Unwrap

func (ss *SecureSession) Unwrap(data []byte) ([]byte, bool, error)

Unwrap decrypts the encrypted data from the peer. It is also used for connection negotiation.

func (*SecureSession) Wrap

func (ss *SecureSession) Wrap(data []byte) ([]byte, error)

Wrap encrypts the provided data for the peer.

type SessionCallbacks

type SessionCallbacks interface {
	GetPublicKeyForId(ss *SecureSession, id []byte) *keys.PublicKey
	StateChanged(ss *SecureSession, state int)
}

SessionCallbacks implements a delegate for SecureSession.
