net.i2p.router.crypto.ratchet.Elg2KeyFactory

All Implemented Interfaces:

Runnable, KeyFactory

public class Elg2KeyFactory
extends I2PThread
implements KeyFactory

Elligator2 for X25519 keys. Try to keep DH pairs at the ready. It's important to do this in a separate thread, because if we run out, the pairs are generated in the NTCP Pumper thread, and it can fall behind.

Since:

0.9.44 from X25519KeyFactory

Method Summary

Modifier and Type	Method	Description
Elg2KeyPair	getKeys()	Pulls a prebuilt keypair from the queue, or if not available, construct a new one.
void	returnUnused(Elg2KeyPair kp)	Return an unused DH key builder to be put back onto the queue for reuse.
void	run()
void	shutdown()	Note that this stops the singleton precalc thread.

Method Details

shutdown

public void shutdown()

Note that this stops the singleton precalc thread. You don't want to do this if there are multiple routers in the JVM. Fix this if you care. See Router.shutdown().

run

public void run()

Specified by:

run in interface Runnable

Overrides:

run in class I2PThread

getKeys

public Elg2KeyPair getKeys()

Pulls a prebuilt keypair from the queue, or if not available, construct a new one.

Specified by:

getKeys in interface KeyFactory

returnUnused

public void returnUnused(Elg2KeyPair kp)

Return an unused DH key builder to be put back onto the queue for reuse.
