Class SSLContextSpi

java.lang.Object
- javax.net.ssl.SSLContextSpi

public abstract class SSLContextSpi
extends Object

This class defines the Service Provider Interface (SPI) for the SSLContext class.

All the abstract methods in this class must be implemented by each cryptographic service provider who wishes to supply the implementation of a particular SSL context.

Since:: 1.4
See Also:: SSLContext

Methods

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
See Also:: SSLContext.init(KeyManager [], TrustManager [], SecureRandom)

engineGetSocketFactory

protected abstract SSLSocketFactory engineGetSocketFactory()

Returns a SocketFactory object for this context.

Returns:: the SocketFactory object
Throws:: 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:: 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.

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()

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.

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
