Method Details

createRecord

public static void createRecord(int recordNum,
 int hop,
 TunnelBuildMessage msg,
 TunnelCreatorConfig cfg,
 Hash replyRouter,
 long replyTunnel,
 RouterContext ctx,
 PublicKey peerKey)

Place the asymmetrically encrypted record in the specified record slot, containing the hop's configuration (as well as the reply info, if it is an outbound endpoint)

Parameters:

msg - out parameter

peerKey - Encrypt using this key. If null, replyRouter and replyTunnel are ignored, and the entire record is filled with random data

Throws:

IllegalArgumentException - if hop bigger than config

layeredEncrypt

public static void layeredEncrypt(I2PAppContext ctx,
 TunnelBuildMessage msg,
 TunnelCreatorConfig cfg,
 List<Integer> order)

Encrypt the records so their hop ident is visible at the appropriate times. Note that this layer-encrypts the build records for the message in-place. Only call this once for a given message.

Parameters:

order - list of hop #s as Integers. For instance, if (order.get(1) is 4), it is peer cfg.getPeer(4)

isBlank

public static boolean isBlank(TunnelCreatorConfig cfg,
 int hop)
