public SSLSocketFactory()
Constructor is used only by subclasses.
public static SocketFactory getDefault()
Returns the default SSL socket factory.
The first time this method is called, the security property "ssl.SocketFactory.provider" is examined. If it is non-null, a class by that name is loaded and instantiated. If that is successful and the object is an instance of SSLSocketFactory, it is made the default SSL socket factory.
Otherwise, this method returns SSLContext.getDefault().getSocketFactory()
. If that call fails, an inoperative factory is returned.

public abstract String[] getDefaultCipherSuites()
Returns the list of cipher suites which are enabled by default. Unless a different list is enabled, handshaking on an SSL connection will use one of these cipher suites. The minimum quality of service for these defaults requires confidentiality protection and server authentication (that is, no anonymous cipher suites).
getSupportedCipherSuites()
public abstract String[] getSupportedCipherSuites()
Returns the names of the cipher suites which could be enabled for use on an SSL connection. Normally, only a subset of these will actually be enabled by default, since this list may include cipher suites which do not meet quality of service requirements for those defaults. Such cipher suites are useful in specialized applications.
getDefaultCipherSuites()
public abstract Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException
Returns a socket layered over an existing socket connected to the named host, at the given port. This constructor can be used when tunneling SSL through a proxy or when negotiating the use of SSL over an existing socket. The host and port refer to the logical peer destination. This socket is configured using the socket options established for this factory.

- if an I/O error occurs when creating the socketNullPointerException
- if the parameter s is nullpublic Socket createSocket(Socket s, InputStream consumed, boolean autoClose) throws IOException
Creates a server mode Socket
layered over an existing connected socket, and is able to read data which has already been consumed/removed from the Socket
's underlying InputStream
.
This method can be used by a server application that needs to observe the inbound data but still create valid SSL/TLS connections: for example, inspection of Server Name Indication (SNI) extensions (See section 3 of TLS Extensions (RFC6066)). Data that has been already removed from the underlying InputStream
should be loaded into the consumed
stream before this method is called, perhaps using a ByteArrayInputStream
. When this Socket
begins handshaking, it will read all of the data in consumed
until it reaches EOF
, then all further data is read from the underlying InputStream
as usual.
The returned socket is configured using the socket options established for this factory, and is set to use server mode when handshaking (see SSLSocket.setUseClientMode(boolean)
).
