Class HashDistance

java.lang.Object

net.i2p.router.util.HashDistance

public class HashDistance
extends Object

Utility for calculating XOR distance between router hashes.

Computes the XOR distance between two router hashes by performing a bitwise XOR operation on the hash data. Used in Kademlia-based distributed hash tables for determining key proximity and routing decisions.

Returns the result as a BigInteger to handle the full 256-bit hash space without overflow issues. The distance metric is fundamental to Kademlia DHT operations including key lookup, peer selection, and network topology analysis.
