SecureSocket class

A high-level class for communicating securely over a TCP socket, using TLS and SSL. The SecureSocket exposes both a Stream and an IOSink interface, making it ideal for using together with other Streams.

Implemented types

Properties

peerCertificate → X509Certificate
Get the peer certificate for a connected SecureSocket. If this SecureSocket 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.

Static Methods

connect(dynamic host, int port, { SecurityContext context, bool onBadCertificate(X509Certificate certificate), List<String> supportedProtocols, Duration timeout }) → Future<SecureSocket>
Constructs a new secure client socket and connects it to the given host on port port. The returned Future will complete with a SecureSocket that is connected and ready for subscription. [...]
override
secure(Socket socket, { dynamic host, SecurityContext context, bool onBadCertificate(X509Certificate certificate) }) → Future<SecureSocket>
Takes an already connected socket and starts client side TLS handshake to make the communication secure. When the returned future completes the SecureSocket has completed the TLS handshake. Using this function requires that the other end of the connection is prepared for TLS handshake. [...]
secureServer(Socket socket, SecurityContext context, { List<int> bufferedData, bool requestClientCertificate: false, bool requireClientCertificate: false, List<String> supportedProtocols }) → Future<SecureSocket>
Takes an already connected socket and starts server side TLS handshake to make the communication secure. When the returned future completes the SecureSocket has completed the TLS handshake. Using this function requires that the other end of the connection is going to start the TLS handshake. [...]
startConnect(dynamic host, int port, { SecurityContext context, bool onBadCertificate(X509Certificate certificate), List<String> supportedProtocols }) → Future<ConnectionTask<SecureSocket>>
Like connect, but returns a Future that completes with a ConnectionTask that can be cancelled if the SecureSocket is no longer needed.
