# RawSecureSocket class abstract interface

`RawSecureSocket` provides a secure (SSL or TLS) network connection.

Client connections to a server are provided by calling RawSecureSocket.connect. A secure server, created with RawSecureServerSocket, also returns `RawSecureSocket` objects representing the server end of a secure connection. The certificate provided by the server is checked using the trusted certificates set in the SecurityContext object. The default SecurityContext object contains a built-in set of trusted root certificates for well-known certificate authorities.

See RawSocket for more information.

Implemented types
  - RawSocket

## Properties

address → InternetAddress
  The InternetAddress used to connect this socket.
  no setter inherited
first → Future<RawSocketEvent>
  The first element of this stream.
  no setter inherited
hashCode → int
  The hash code for this object.
  no setter inherited
isBroadcast → bool
  Whether this stream is a broadcast stream.
  no setter inherited
isEmpty → Future<bool>
  Whether this stream contains any elements.
  no setter inherited
last → Future<RawSocketEvent>
  The last element of this stream.
  no setter inherited
length → Future<int>
  The number of elements in this stream.
  no setter inherited
peerCertificate → X509Certificate?
  Get the peer certificate for a connected RawSecureSocket. If this RawSecureSocket is the server end of a secure socket connection, peerCertificate will return the client certificate, or null, if no client certificate was received. If it is the client end, peerCertificate will return the server's certificate.
  no setter
port → int
  The port used by this socket.
  no setter inherited
readEventsEnabled ↔ bool
  Set or get, if the RawSocket should listen for RawSocketEvent.read and RawSocketEvent.readClosed events. Default is `true`.
  getter/setter pair inherited
remoteAddress → InternetAddress
  The remote InternetAddress connected to by this socket.
  no setter inherited
remotePort → int
  The remote port connected to by this socket.
  no setter inherited
runtimeType → Type
  A representation of the runtime type of the object.
  no setter inherited
selectedProtocol → String?
  The protocol which was selected during protocol negotiation.
  no setter
single → Future<RawSocketEvent>
  The single element of this stream.
  no setter inherited
writeEventsEnabled ↔ bool
  Set or get, if the RawSocket should listen for RawSocketEvent.write events. Default is `true`. This is a one-shot listener, and writeEventsEnabled must be set to true again to receive another write event.
  getter/setter pair inherited
