TLS/SSL支持

阻塞型连接可以依附在任意socket上，对SSL提供直接支持。任何SSLSocket势力都可以依附于一个阻塞型连接，从而使所有通过此连接传输的报文都可以通过TLS/SSL加密。

SSLContext sslcontext = SSLContexts.createSystemDefault();
SocketFactory sf = sslcontext.getSocketFactory();
SSLSocket socket = (SSLSocket) sf.createSocket("somehost", 443);
// Enforce TLS and disable SSL
socket.setEnabledProtocols(new String[] {
        "TLSv1",
        "TLSv1.1",
        "TLSv1.2" });
// Enforce strong ciphers
socket.setEnabledCipherSuites(new String[] {
        "TLS_RSA_WITH_AES_256_CBC_SHA",
        "TLS_DHE_RSA_WITH_AES_256_CBC_SHA",
        "TLS_DHE_DSS_WITH_AES_256_CBC_SHA" });
DefaultBHttpClientConnection conn = new DefaultBHttpClientConnection(8 * 1204);
conn.bind(socket);
