      • 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,
                                                                       java.net.URI remote,

                                                                throws java.lang.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:
        java.lang.Exception - if an error occurs while creating the SslHandler instance.
      • createJdkSslContext

        public static javax.net.ssl.SSLContext createJdkSslContext​(TransportOptions options)
                                                            throws java.lang.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:
        java.lang.Exception - if an error occurs while creating the context.
      • createJdkSslEngine

        public static javax.net.ssl.SSLEngine createJdkSslEngine​(java.net.URI remote,
                                                                 javax.net.ssl.SSLContext context,

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