Class SSLContext

java.lang.Object
  javax.net.ssl.SSLContext

public class SSLContext
extends Object

A "meta-factory" for protocol-specific socket and server socket factories. This class serves as a clearinghouse for socket factories and cached session contexts for a particular protocol, such as SSLv3.

Constructor Summary

protected

SSLContext(SSLContextSpi ctxSpi, Provider provider, String protocol) Create a new SSL context.

Method Summary

SSLSessionContext	getClientSessionContext() Returns the set of SSL contexts available for client connections.
static SSLContext	getInstance(String protocol) Get an instance of a context for the specified protocol from the first provider that implements it.
static SSLContext	getInstance(String protocol, Provider provider) Get an instance of a context for the specified protocol from the specified provider.
static SSLContext	getInstance(String protocol, String provider) Get an instance of a context for the specified protocol from the named provider.
String	getProtocol() Returns the protocol name of this context.
Provider	getProvider() Returns the provider of this implementation.
SSLSessionContext	getServerSessionContext() Returns the set of SSL contexts available for server connections.
SSLServerSocketFactory	getServerSocketFactory() Returns the factory for server SSL sockets.
SSLSocketFactory	getSocketFactory() Returns the factory for client SSL sockets.
void	init(KeyManager[] keyManagers, TrustManager[] trustManagers, SecureRandom random) Initializes this context and prepares it for producing socket factories.

Constructor Detail

SSLContext

protected SSLContext(SSLContextSpi ctxSpi,
                     Provider provider,
                     String protocol)

Create a new SSL context.

Parameters:

ctxSpi - The context engine.

provider - The provider of the implementation.

protocol - The name of the SSL protocol.

Method Detail

getInstance

public static final SSLContext getInstance(String protocol)
                                    throws NoSuchAlgorithmException

Get an instance of a context for the specified protocol from the first provider that implements it.

Parameters:

protocol - The name of the protocol to get a context for.

Returns:

The new context.

Throws:

NoSuchAlgorithm - If no provider implements the given protocol.

NoSuchAlgorithmException

getInstance

public static final SSLContext getInstance(String protocol,
                                           String provider)
                                    throws NoSuchAlgorithmException,
                                           NoSuchProviderException

Get an instance of a context for the specified protocol from the named provider.

Parameters:

protocol - The name of the protocol to get a context for.

provider - The name of the provider to get the implementation from.

Returns:

The new context.

Throws:

NoSuchAlgorithmException - If the provider does not implement the given protocol.

NoSuchProviderException - If the named provider does not exist.

IllegalArgumentException - If provider is null.

getInstance

public static final SSLContext getInstance(String protocol,
                                           Provider provider)
                                    throws NoSuchAlgorithmException

Get an instance of a context for the specified protocol from the specified provider.

Parameters:

protocol - The name of the protocol to get a context for.

provider - The name of the provider to get the implementation from.

Returns:

The new context.

Throws:

NoSuchAlgorithmException - If the provider does not implement the given protocol.

IllegalArgumentException - If provider is null.
