Class OutboundGatewayProcessor

java.lang.Object
net.i2p.router.tunnel.OutboundGatewayProcessor
class OutboundGatewayProcessor
extends Object
Turn the preprocessed tunnel data into something that can be delivered to the first hop in the tunnel. The crypto used in this class is also used by the InboundEndpointProcessor, as it's the same 'undo' function of the tunnel crypto.

    • process

      public void process​(byte[] orig, int offset, int length)
      Since we are the outbound gateway, pick a random IV and wrap the preprocessed data so that it will be exposed at the endpoint.
      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.

    • decrypt

      static void decrypt​(I2PAppContext ctx, byte[] orig, int offset, int length, HopConfig config)
      Undo the crypto for a single hop. This is used by both the outbound gateway (preemptively undoing the crypto peers will add) and by the inbound endpoint.
      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.
