gegtik Posted November 21, 2005 Report Share Posted November 21, 2005 I am requesting the option to encrypt headers like bitcomet does. My ISP is packet-shaping torrent data and so utorrent is completely useless to me right now. If it were possible to encrypt torrent headers, I could bypass this problem.( http://www.google.ca/search?q=bitcomet+%22protocol+header+encrypt%22 )Please add this so I can use utorrent once again!

boo Posted November 21, 2005 Report Share Posted November 21, 2005 this has been requested several times before. ludde will implement this once he finds out how to do it,because bitcomet is a closed source and there is no documentation on enrypted BT headers.

StirolXXX Posted November 21, 2005 Report Share Posted November 21, 2005 I am too interested in this feature! Link to comment Share on other sites More sharing options...

I haven't used it yet but I plan to when i get home Link to comment Share on other sites More sharing options...
boo Posted November 21, 2005 Report Share Posted November 21, 2005 gegtik,the BT headers you send are encrypted and the only bt headers you recieve that are encrypted,are those that are sent from other BitComet users. Link to comment Share on other sites More sharing options...

StirolXXX Posted November 21, 2005 Report Share Posted November 21, 2005 Nope! To BC - Encrypt, non-BC - no encryption, but ISP shaping... Link to comment Share on other sites More sharing options...
1c3d0g Posted November 21, 2005 Report Share Posted November 21, 2005 Yeah, for some people this feature is necessary, unfortunately it isn't documented anywhere on how to implement it. Link to comment Share on other sites More sharing options...
Klaus_1250 Posted November 21, 2005 Report Share Posted November 21, 2005 If it was documented, it would be useless. ISP's would decrypt the packets too and see that is BT-traffic.In fact, if ISP's had more powerfull hardware, they could circumvent the entire encryption packets. BitComet also connect to clients that do not use encryption. They could use those packets to log/figure out on what port you are running BitComet on, and traffic shape all network traffic to/from that specific port. Using a different random port each time would help somewhat, but it wouldn't take long to figure it out.In the end, the only way to bypass traffic-shaping is using some sort of VPN/SSL-tunnel to a location outside of your ISP's network.

wiggo Posted November 21, 2005 Report Share Posted November 21, 2005 It doesn't matter if it would have been documentated if it was implemented in the correct way. Since the data is encrypted using an unique key for each session (ex the torrents hash), there's no way for the ISP to detect the BT traffic even if the encryption method would have been documentated.There's no excuse at all for not making the protocol official. I guess BitComet keeps it for themself just because they want users to be dependent to use BitComet if thier ISP shape BT traffic. Link to comment Share on other sites More sharing options...
gegtik Posted November 21, 2005 Author Report Share Posted November 21, 2005 well, not to put too much on utorrent's plate, but encrypting/decrypting data should not be an impossible task -- perhaps utorrent could spearhead an open implementation.

Klaus_1250 Posted November 21, 2005 Report Share Posted November 21, 2005 I don't think you want that either. There are already two DHT's in use, why also add multiple encryption ways? Link to comment Share on other sites More sharing options...
Firon Posted November 21, 2005 Report Share Posted November 21, 2005 Because the BitComet people aren't too likely to share their encryption method with ludde. Link to comment Share on other sites More sharing options...
Klaus_1250 Posted November 21, 2005 Report Share Posted November 21, 2005 But if µTorrent would like to implement something similiar, they would need to get some support from other BitTorrent-devellopers (having two non-standard encryption methods is not any better, even if one of them is documented). That would take (a lot of) effort and time. But, I remember reading that several people were already trying to dismantle BitComet's encryption. How far are they?

gegtik Posted November 21, 2005 Author Report Share Posted November 21, 2005 I don't think you want that either. There are already two DHT's in use, why also add multiple encryption ways?if ludde develops and shares an open encryption scheme, there's no reason to think it couldn't be adopted quite easily by other devs, leaving bitcomet to either adopt it or be the odd man out. Again the key here is to openly share it with other torrent app devs. Link to comment Share on other sites More sharing options...
Klaus_1250 Posted November 21, 2005 Report Share Posted November 21, 2005 Well, there is a difference in develloping something on your own and sharing it, and develloping something with the entire BT-community. Openly sharing something does not mean acceptation and implementation among other devellopers. Link to comment Share on other sites More sharing options...
adrianmk Posted November 21, 2005 Report Share Posted November 21, 2005 If it was documented, it would be useless. ISP's would decrypt the packets too and see that is BT-traffic..Some of the best and most trusted ciphers have their specifications completely open. They don't rely on obscurity of the protocol to provide any security. No system should. Link to comment Share on other sites More sharing options...
