java.lang.Objectjavax.net.ssl.SSLContext
public class SSLContext
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 | |
---|---|
SSLEngine |
createSSLEngine()
Creates a new SSLEngine for this context. |
SSLEngine |
createSSLEngine(String host,
int port)
Creates a new SSLEngine for this context, with a given
host name and port number. |
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. |
