Package net.i2p.router.crypto.pqc

Class MLKEMKeyFactory

java.lang.Object

java.lang.Thread

net.i2p.util.I2PThread

net.i2p.router.crypto.pqc.MLKEMKeyFactory

All Implemented Interfaces:

Runnable, KeyFactory

public class MLKEMKeyFactory
extends I2PThread
implements KeyFactory

Try to keep key pairs at the ready. It's important to do this in a separate thread, because if we run out, the pairs are generated other threads, and it can fall behind. Started by ECIESAEADEngine. One type per-thread. Only used for 768, for now.

Since:

0.9.68 adapted from X25519KeyFactory

MLKEMKeyFactory

public MLKEMKeyFactory(I2PAppContext ctx,
 EncType type)

Alice side only

Parameters:

type - must be one of the internal types MLKEM*_INT

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 KeyPair 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(KeyPair kp)

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