Method Detail

isOpenSSLPossible

public static boolean isOpenSSLPossible(TransportOptions options)

Determines if Netty OpenSSL support is available and applicable based on the configuration in the given TransportOptions instance.

Parameters:

options - The configuration of the Transport being created.

Returns:

true if OpenSSL support is available and usable given the requested configuration.

createSslHandler

public static io.netty.handler.ssl.SslHandler createSslHandler(io.netty.buffer.ByteBufAllocator allocator,
                                                               URI remote,
                                                               TransportOptions options)
                                                        throws Exception

Creates a Netty SslHandler instance for use in Transports that require an SSL encoder / decoder. If the given options contain an SSLContext override, this will be used directly when creating the handler. If they do not, an SSLContext will first be created using the other option values.

Parameters:

allocator - The Netty Buffer Allocator to use when Netty resources need to be created.

remote - The URI of the remote peer that the SslHandler will be used against.

options - The SSL options object to build the SslHandler instance from.

Returns:

a new SslHandler that is configured from the given options.

Throws:

Exception - if an error occurs while creating the SslHandler instance.

createJdkSslContext

public static SSLContext createJdkSslContext(TransportOptions options)
                                      throws Exception

Create a new SSLContext using the options specific in the given TransportOptions instance.

Parameters:

options - the configured options used to create the SSLContext.

Returns:

a new SSLContext instance.

Throws:

Exception - if an error occurs while creating the context.

createJdkSslEngine

public static SSLEngine createJdkSslEngine(URI remote,
                                           SSLContext context,
                                           TransportOptions options)
                                    throws Exception

Create a new JDK SSLEngine instance in client mode from the given SSLContext and TransportOptions instances.

Parameters:

remote - the URI of the remote peer that will be used to initialize the engine, may be null if none should.

context - the SSLContext to use when creating the engine.

options - the TransportOptions to use to configure the new SSLEngine.

Returns:

a new SSLEngine instance in client mode.

Throws:

Exception - if an error occurs while creating the new SSLEngine.

createOpenSslContext

public static io.netty.handler.ssl.SslContext createOpenSslContext(TransportOptions options)
                                                            throws Exception

Create a new Netty SslContext using the options specific in the given TransportOptions instance.

Parameters:

options - the configured options used to create the SslContext.

Returns:

a new SslContext instance.

Throws:

Exception - if an error occurs while creating the context.

createOpenSslEngine

public static SSLEngine createOpenSslEngine(io.netty.buffer.ByteBufAllocator allocator,
                                            URI remote,
                                            io.netty.handler.ssl.SslContext context,
                                            TransportOptions options)
                                     throws Exception

Create a new OpenSSL SSLEngine instance in client mode from the given SSLContext and TransportOptions instances.

Parameters:

allocator - the Netty ByteBufAllocator to use to create the OpenSSL engine

remote - the URI of the remote peer that will be used to initialize the engine, may be null if none should.

context - the Netty SslContext to use when creating the engine.

options - the TransportOptions to use to configure the new SSLEngine.

Returns:

a new Netty managed SSLEngine instance in client mode.

Throws:

Exception - if an error occurs while creating the new SSLEngine.
