Method Detail

• engineInit

  protected abstract void engineInit​(KeyManager[] km,
                                     TrustManager[] tm,
                                     SecureRandom sr)
                              throws KeyManagementException

  Initializes this context.

  Parameters:

  km - the sources of authentication keys

  tm - the sources of peer authentication trust decisions

  sr - the source of randomness

  Throws:

  KeyManagementException - if this operation fails

  SSLContext.init(KeyManager [], TrustManager [], SecureRandom)

• engineGetSocketFactory

  protected abstract SSLSocketFactory engineGetSocketFactory()

  Returns a SocketFactory object for this context.

  Returns:

  the SocketFactory object

  Throws:

  UnsupportedOperationException - if the underlying provider does not implement the operation.

  IllegalStateException - if the SSLContextImpl requires initialization and the engineInit() has not been called

  See Also:

  SSLContext.getSocketFactory()

• engineGetServerSocketFactory

  protected abstract SSLServerSocketFactory engineGetServerSocketFactory()

  Returns a ServerSocketFactory object for this context.

  Returns:

  the ServerSocketFactory object

  Throws:

  UnsupportedOperationException - if the underlying provider does not implement the operation.

  IllegalStateException - if the SSLContextImpl requires initialization and the engineInit() has not been called

  See Also:

  SSLContext.getServerSocketFactory()

• engineCreateSSLEngine

  protected abstract SSLEngine engineCreateSSLEngine()

  Creates a new SSLEngine using this context.

  Applications using this factory method are providing no hints for an internal session reuse strategy. If hints are desired, engineCreateSSLEngine(String, int) should be used instead.

  Some cipher suites (such as Kerberos) require remote hostname information, in which case this factory method should not be used.

  Implementation Note:

  It is provider-specific if the returned SSLEngine uses client or server mode by default for the (D)TLS connection. The JDK SunJSSE provider implementation uses server mode by default. However, it is recommended to always set the desired mode explicitly by calling SSLEngine.setUseClientMode() before invoking other methods of the SSLEngine.

  Returns:

  the SSLEngine Object

  Throws:

  IllegalStateException - if the SSLContextImpl requires initialization and the engineInit() has not been called

  Since:

  1.5

  SSLContext.createSSLEngine()

• engineCreateSSLEngine

  protected abstract SSLEngine engineCreateSSLEngine​(String host,
                                                     int port)

  Creates a SSLEngine using this context.

  Applications using this factory method are providing hints for an internal session reuse strategy.

  Some cipher suites (such as Kerberos) require remote hostname information, in which case peerHost needs to be specified.

  Implementation Note:

  It is provider-specific if the returned SSLEngine uses client or server mode by default for the (D)TLS connection. The JDK SunJSSE provider implementation uses server mode by default. However, it is recommended to always set the desired mode explicitly by calling SSLEngine.setUseClientMode() before invoking other methods of the SSLEngine.

  Parameters:

  host - the non-authoritative name of the host

  port - the non-authoritative port

  Returns:

  the SSLEngine Object

  Throws:

  IllegalStateException - if the SSLContextImpl requires initialization and the engineInit() has not been called

  Since:

  1.5

  See Also:

  SSLContext.createSSLEngine(String, int)

• engineGetServerSessionContext

  protected abstract SSLSessionContext engineGetServerSessionContext()

  Returns a server SSLSessionContext object for this context.

  Returns:

  the SSLSessionContext object

  See Also:

  SSLContext.getServerSessionContext()

• engineGetClientSessionContext

  protected abstract SSLSessionContext engineGetClientSessionContext()

  Returns a client SSLSessionContext object for this context.

  Returns:

  the SSLSessionContext object

  See Also:

  SSLContext.getClientSessionContext()

• engineGetDefaultSSLParameters

  protected SSLParameters engineGetDefaultSSLParameters()

  Returns a copy of the SSLParameters indicating the default settings for this SSL context.

  The parameters will always have the ciphersuite and protocols arrays set to non-null values.

  The default implementation obtains the parameters from an SSLSocket created by calling the SocketFactory.createSocket() method of this context's SocketFactory.

  Returns:

  a copy of the SSLParameters object with the default settings

  Throws:

  UnsupportedOperationException - if the default SSL parameters could not be obtained.

  Since:

  1.6

• engineGetSupportedSSLParameters

  protected SSLParameters engineGetSupportedSSLParameters()

  Returns a copy of the SSLParameters indicating the maximum supported settings for this SSL context.

  The parameters will always have the ciphersuite and protocols arrays set to non-null values.

  The default implementation obtains the parameters from an SSLSocket created by calling the SocketFactory.createSocket() method of this context's SocketFactory.

  Returns:

  a copy of the SSLParameters object with the maximum supported settings

  Throws:

  UnsupportedOperationException - if the supported SSL parameters could not be obtained.

  Since:

  1.6
