Class JSSSocket

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable
    public class JSSSocket
extends javax.net.ssl.SSLSocket
    SSL-enabled socket following the javax.net.ssl.SSLSocket interface. Most users will want to use the JSSSocketFactory provided by the Java Provider interface instead of using this class directly. This SSLSocket implementation is a wrapped implementation. In particular, we need to consume an existing Socket (via the consumeSocket(...) call) which we actually send data over. When called from a socket factory, this additional socket will be automatically created for the caller. This is necessary because SSLSocketFactory includes a mode which wraps an existing socket. All JSSSocket instances have a underlying SocketChannel, of type JSSSocketChannel. Notably lacking is a javax.net.ssl.SSLSocketChannel type, so JSSSocketChannel includes no additional SSL-specific options. However, the core of the SSLEngine wrapping logic exists there. In order to interoperate with JSSEngine, many of the adjacent methods have been included in this class as well. This socket can either be a client or a server, depending on how it was created. For more information, see the javax.net.ssl.SSLSocket documentation. To construct a (useful) new instance, the following calls must be made: - new JSSSocket(); - consumeSocket(inst); - initSSLEngine(...); - setKeyManagers(...); - setTrustManagers(...); Optionally, setSSLContext(...) could be called to provide the SSLContext from which the SSLEngine should be constructed. This should be called prior to initSSLEngine(...) being called.

        public JSSSocket()
        Start building a new JSSSocket. We specifically avoid creating any other constructors as we wish to consume an existing socket rather than creating a new one.

    • Method Detail

      • consumeSocket

        public void consumeSocket​(java.net.Socket parent)
                   throws java.io.IOException
        Consume a parent socket, utilizing it for all read/write operations. This JSSSocket instance will inherit all information about the connection from this underlying socket. When utilized in a JSSSocket, callers should refrain from interacting with the underlying socket directly until the TLS connection is closed. Otherwise, messages may get dropped.
        Throws:
        java.io.IOException

      • getSSLContext

        protected javax.net.ssl.SSLContext getSSLContext()

        public void setSSLContext​(javax.net.ssl.SSLContext ctx)
                   throws java.io.IOException
        Explicitly set the SSLContext utilized by this JSSSocket instance. This enables JSSServerSocket to copy its SSLContext over to the accepted JSSSocket.
        Throws:

      • setConsumedData

        public void setConsumedData​(java.io.InputStream consumed)
