public class TLSUniqueChannelBinding
extends ChannelBinding

This class implements the tls-unique channel binding according to RFC 5929.

RFC 5929 specifies the tls-unique channel binding as the first Finished message verify data in the most recent handshake.

An application that is interested to capture the tls-unique channel binding value has to announce its interest by adding a ChannelBindings containing the TLSUniqueChannelBinding to the SSLContext object, e.g.:

 ChannelBindings channelBindings = new ChannelBindings();
 channelBindings.addChannelBinding(new TLSServerEndPointChannelBinding());
 context.setChannelBindings(channelBindings);
 

After having completed the handshake the tls-unique channel binding value can be obtained from the SSLSocket:

 ChannelBindings chBndgs = socket.getChannelBindings();
 if (chBndgs != null) {
   TLSUniqueChannelBinding tlsUnique = (TLSUniqueChannelBinding)chBndgs.getChannelBinding(TLSUniqueChannelBinding.TYPE);
   if (tlsUnique != null) {
     System.out.println("tls-unique: " + Util.toString(tlsUnique.getData()));
   }
   TLSServerEndPointChannelBinding tlsServerEndPoint = (TLSServerEndPointChannelBinding)chBndgs.getChannelBinding(TLSServerEndPointChannelBinding.TYPE);
   if (tlsServerEndPoint != null) {
     System.out.println("tls-server-end-point: " + Util.toString(tlsServerEndPoint.getData()));
   }
 }
