How to use

ZERO

function

in

BigInteger

function generateSecretKey(session, packet) {
  const cipherPublicKey = packet.readString();
  const sharedKey = HabboEncryption.calculateDiffieHellmanSharedKey(cipherPublicKey);
  
  if (sharedKey.equals(BigInteger.ZERO)) {
    return;
  }
  
  session.enableRC4(sharedKey.toByteArray());
  session.sendPacket(new CompleteDiffieHandshakeComposer(HabboEncryption.PublicKey.toString()));
}
