ddn.net.dtls.engine

Main DTLS engine for client and server roles.

The engine manages DTLS connections over a single datagram socket. In server mode, it can handle multiple peers simultaneously. In client mode, it connects to a single server.

Thread safety: NOT thread-safe. All calls must be serialized.

Example (client):

auto engine = new NativeDtlsEngine(transport, timer, "example.com");
engine.setMinVersion(DtlsVersion.DTLS_1_2);
while (engine.handshake() != TlsProgress.DONE) {
   // poll and handle I/O
}

Example (server):

auto engine = new NativeDtlsEngine(transport, timer);
engine.setCertificateChain(certs);
engine.setPrivateKey(key);
// Process incoming datagrams in event loop
