final String getProtocol()
Returns the name of the secure socket protocol of this instance.
final Provider getProvider()
Returns the provider of this SSLContext instance.
final SSLSessionContext getServerSessionContext()
Returns the SSL session context that encapsulates the set of SSL sessions that can be used for handshake of server-side SSL sockets.
final SSLServerSocketFactory getServerSocketFactory()
Returns a server socket factory for this instance.
final SSLSocketFactory getSocketFactory()
Returns a socket factory for this instance.
final SSLParameters getSupportedSSLParameters()
Returns SSL handshake parameters for SSLSockets that includes all supported cipher suites and protocols.
final void init(KeyManager[] km, TrustManager[] tm, SecureRandom sr)
Initializes this SSLContext instance.
static void setDefault(SSLContext sslContext)
Sets the default SSLContext instance as returned by getDefault() to a non-null initialized value.

Protected Constructors

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

Since: API Level 1

Creates a new SSLContext.

Parameters
contextSpi the implementation delegate.
provider the provider.
protocol the protocol name.

Public Methods

public final SSLEngine createSSLEngine (String peerHost, int peerPort)

Since: API Level 1

Creates an SSLEngine instance from this context with the specified hostname and port.

Parameters
peerHost the name of the host
peerPort the port
Returns
  • an SSLEngine instance from this context.
Throws
UnsupportedOperationException if the provider does not support the operation.

public final SSLEngine createSSLEngine ()

Since: API Level 1

Creates an SSLEngine instance from this context.

Returns
  • an SSLEngine instance from this context.
Throws
UnsupportedOperationException if the provider does not support the operation.

public final SSLSessionContext getClientSessionContext ()

Since: API Level 1

Returns the SSL session context that encapsulates the set of SSL sessions that can be used for handshake of client-side SSL sockets.

Returns
  • the SSL client session context for this context or null if the underlying provider does not provide an implementation of the SSLSessionContext interface.

public static SSLContext getDefault ()

Since: API Level 9

Returns the default SSLContext. The default SSL context can be set with setDefault(SSLContext). If not, one will be created with SSLContext.getInstance("Default"), which will already be initialized.

Throws
NoSuchAlgorithmException if there is a problem creating the default instance.

public final SSLParameters getDefaultSSLParameters ()

Since: API Level 9

Returns the default SSL handshake parameters for SSLSockets created by this SSLContext.

Throws
UnsupportedOperationException

public static SSLContext getInstance (String protocol, String provider)

Since: API Level 1

Creates a new SSLContext instance for the specified protocol from the specified provider.

Parameters
protocol the requested protocol to create a context for.
provider the name of the provider that provides the requested protocol.
Returns
  • an SSLContext for the requested protocol.
Throws
NoSuchAlgorithmException if the specified provider cannot provider the requested protocol.
NoSuchProviderException if the specified provider does not exits.
NullPointerException if protocol is null (instead of NoSuchAlgorithmException as in 1.4 release)

public static SSLContext getInstance (String protocol, Provider provider)

Since: API Level 1

Creates a new SSLContext instance for the specified protocol from the specified provider.

Parameters
protocol the requested protocol to create a context for
provider the provider that provides the requested protocol.
Returns
  • an SSLContext for the requested protocol.
Throws
NoSuchAlgorithmException if the specified provider cannot provide the requested protocol.
NullPointerException if protocol is null (instead of NoSuchAlgorithmException as in 1.4 release)

public static SSLContext getInstance (String protocol)

Since: API Level 1

Creates a new SSLContext instance for the specified protocol.

Parameters
protocol the requested protocol to create a context for.
Returns
  • the created SSLContext instance.
Throws
NoSuchAlgorithmException if no installed provider can provide the requested protocol
NullPointerException if protocol is null (instead of NoSuchAlgorithmException as in 1.4 release)
