Example 1 with AuthLayerMessage

use of sugar.free.sightparser.authlayer.AuthLayerMessage in project SightRemote by TebbeUbben.

the class AuthLayerProcessor method onInboundMessage.

@Override
public void onInboundMessage(Object message, Pipeline pipeline) throws Exception {
    if (!(message instanceof ByteBuf))
        return;
    ByteBuf data = (ByteBuf) message;
    while (data.size() >= 37) {
        int length = data.getUInt16LE(4);
        if (data.size() < length + 8)
            return;
        try {
            AuthLayerMessage authLayerMessage = AuthLayerMessage.deserialize(data, pipeline.getLastNonceReceived(), pipeline.getDerivedKeys() != null ? pipeline.getDerivedKeys().getIncomingKey() : null);
            pipeline.setLastNonceReceived(authLayerMessage.getNonce());
            pipeline.setCommID(authLayerMessage.getCommID());
            pipeline.receive(authLayerMessage);
        } catch (InvalidNonceError | InvalidAuthCRCError | InvalidTrailerError e) {
            data.shift(data.size());
            throw e;
        }
