disable encryption

[wenchaopeng]

what do I need to do to unencrypt the message，I look at the source code, there should be no place to set，or I missed it
the source code is as follows：

message TopicDescriptor {
	optional string name = 1;
	optional AuthOpts auth = 2;
	optional EncOpts enc = 3;

	message AuthOpts {
		optional AuthMode mode = 1;
		repeated bytes keys = 2; // root keys to trust

		enum AuthMode {
			NONE = 0; // no authentication, anyone can publish
			KEY = 1; // only messages signed by keys in the topic descriptor are accepted
			WOT = 2; // web of trust, certificates can allow publisher set to grow
		}
	}

	message EncOpts {
		optional EncMode mode = 1;
		repeated bytes keyHashes = 2; // the hashes of the shared keys used (salted)

		enum EncMode {
			NONE = 0; // no encryption, anyone can read
			SHAREDKEY = 1; // messages are encrypted with shared key
			WOT = 2; // web of trust, certificates can allow publisher set to grow
		}
	}
}


func (p *PubSub) Subscribe(topic string, opts ...SubOpt) (*Subscription, error) {
	td := pb.TopicDescriptor{Name: &topic}

	return p.SubscribeByTopicDescriptor(&td, opts...)
}

func (p *PubSub) SubscribeByTopicDescriptor(td *pb.TopicDescriptor, opts ...SubOpt) (*Subscription, error) {
	if td.GetAuth().GetMode() != pb.TopicDescriptor_AuthOpts_NONE {
		return nil, fmt.Errorf("auth mode not yet supported")
	}
	if td.GetEnc().GetMode() != pb.TopicDescriptor_EncOpts_NONE {
		return nil, fmt.Errorf("encryption mode not yet supported")
	}
	topic, _, err := p.tryJoin(td.GetName())
	if err != nil {
		return nil, err
	}

	return topic.Subscribe(opts...)
}

That code is out of date and should probably be removed at this point. Messages are encrypted at the transport layer, not within pubsub itself.

OK,Let me see exactly where，during the process of using libp2p, I found that the CPU usage is very high, most of which is rsa encryption and decryption.

sorry，I didn't find where to set the encrypted transmission. Could you give me some tips

has been resolved, thanks for your help
