Document

Sets the cryptographic algorithm constraints, which will be used in addition to any configured by the runtime environment.

Usage

From source file:Test.java

public static void main(String[] arstring) throws Exception {
        SSLServerSocketFactory sslServerSocketFactory = (SSLServerSocketFactory) SSLServerSocketFactory
                .getDefault();//from w ww.  j av a 2 s . c o  m
        SSLServerSocket sslServerSocket = (SSLServerSocket) sslServerSocketFactory.createServerSocket(9999);
        System.out.println("Waiting for a client ...");
        SSLSocket sslSocket = (SSLSocket) sslServerSocket.accept();

        SSLParameters parameters = sslSocket.getSSLParameters();
        parameters.setAlgorithmConstraints(new SimpleConstraints());

        AlgorithmConstraints constraints = parameters.getAlgorithmConstraints();
        System.out.println("Constraint: " + constraints);

        String endPoint = parameters.getEndpointIdentificationAlgorithm();
        System.out.println("End Point: " + endPoint);

        System.out.println("Local Supported Signature Algorithms");
        if (sslSocket.getSession() instanceof ExtendedSSLSession) {
            ExtendedSSLSession extendedSSLSession = (ExtendedSSLSession) sslSocket.getSession();
            String alogrithms[] = extendedSSLSession.getLocalSupportedSignatureAlgorithms();
            for (String algorithm : alogrithms) {
                System.out.println("Algortihm: " + algorithm);
            }
        }

        System.out.println("Peer Supported Signature Algorithms");

                    .getPeerSupportedSignatureAlgorithms();
            for (String algorithm : alogrithms) {
                System.out.println("Algortihm: " + algorithm);
            }
        }

        InputStream inputstream = sslSocket.getInputStream();
        InputStreamReader inputstreamreader = new InputStreamReader(inputstream);
        BufferedReader bufferedreader = new BufferedReader(inputstreamreader);

        SSLSession session = sslSocket.getHandshakeSession();
        if (session != null) {
            System.out.println("Last accessed: " + new Date(session.getLastAccessedTime()));
        }

        String string = null;
        while ((string = bufferedreader.readLine()) != null) {
            System.out.println(string);
            System.out.flush();
        }

    }
