net.i2p.router.transport.crypto.DHSessionKeyBuilder.PrecalcRunner

All Implemented Interfaces:

Runnable, DHSessionKeyBuilder.Factory

Enclosing class:

DHSessionKeyBuilder

public static class DHSessionKeyBuilder.PrecalcRunner
extends I2PThread
implements DHSessionKeyBuilder.Factory

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.
