Class InboundEndpointProcessor

java.lang.Object

net.i2p.router.tunnel.InboundEndpointProcessor

class InboundEndpointProcessor
extends Object

Receive the inbound tunnel message, removing all of the layers added by earlier hops to recover the preprocessed data sent by the gateway. This delegates the crypto to the OutboundGatewayProcessor, since the tunnel creator does the same thing in both instances.

InboundEndpointProcessor

public InboundEndpointProcessor(RouterContext ctx,
                                TunnelCreatorConfig cfg,
                                IVValidator validator)

Method Detail

getConfig

public TunnelCreatorConfig getConfig()

getDestination

public Hash getDestination()

retrievePreprocessedData

public boolean retrievePreprocessedData(byte[] orig,
                                        int offset,
                                        int length,
                                        Hash prev)

Undo all of the encryption done by the peers in the tunnel, recovering the preprocessed data sent by the gateway.

Parameters:

orig - original data with an extra 16 byte IV prepended.

offset - index into the array where the extra 16 bytes (IV) begins

length - how much of orig can we write to (must be a multiple of 16). Should always be 1024 bytes.

Returns:

true if the data was recovered (and written in place to orig), false if it was a duplicate or from the wrong peer.
