Download Torrent Trackers Using Hash

Jun 25, 2011 - I have started using µTorrent to download torrents. Download the files that are associated with the hash file, then use a tool such as MD5. QBittorrent: how to add a torrent using it's hash? Ask Question. Urn:btih:INFOHASH (where the INFOHASH is the hash number) But the hash appear like 0000000. Any idea how to add a torrent from the hash? Share| improve this. You must need trackers for a torrent to be downloaded in magnet link here is an api which.

I did try to Use 'add torrent link' pasting

magnet:?xt=urn:btih:INFOHASH (where the INFOHASH is the hash number)

But the hash appear like 00000000000000000

Any idea how to add a torrent from the hash ?

you must need trackers for a torrent to be downloaded in magnet link here is an api which gives you current seeders and leechers include with the magnet link by just using the torrent infohash

try this hash to magnet generating apihope this helps

If you have visited a Bittorrent website or torrent search engine lately you might have come upon magnet links that were offered on the torrent download pages. Chance is the magnet link did not really bother you since the torrent link was offered as well on the download page so that it could be downloaded and added to the Bittorrent software.

A closer look at the standard process of downloading files via torrents reveals several factors and parties that are necessary for this. The user needs a Bittorrent client like uTorrent or Vuze, a torrent file that is usually downloaded from a Bittorrent server which functions as a tracker and torrent provider and of course other seeders and leechers of that torrent.

A Bittorrent magnet link contains all the information needed to start downloading the files from peers directly. It is a server-less way of retrieving the right information to start downloading the requested files. A magnet link therefor is theoretically all that is needed to download files from other peers in the Bittorrent network. Magnet links can be distributed by email, messaging and other forms of communication but are most often found on the torrent sites that usually offer both torrent and magnet links to their users.

A magnet consists of several parts:

magnet: (This is the magnet link identifier)
?xt=urn:btih: (Defines a Bittorrent Info Hash, the Edonkey identifier would for instance look like this xt=urn:ed2k:)
5dee65101db281ac9c46344cd6b175cdcad53426 (The content hash)
&dn=name (The name of the file)

The full magnet link would look like this magnet:?xt=urn:btih:5dee65101db281ac9c46344cd6b175cdcad53426&dn=download. Detailed information about additional Magnet Link parameters are listed on Wikipedia. One useful parameter that has not been mentioned yet is the as= parameter which contains encrypted information about a download source. This speeds up the process of finding the first peers.

Main Advantages of Magnet Links

The main advantage for Bittorrent indexers is that they do not have to store the torrents on their servers anymore which could be beneficial for them in several ways. It could reduce the pressure from the media creation industry and reduce hardware infrastructure expenses thanks to less tracking and downloading.

The end users on the other hand benefit from Magnet Links as well. All they need is the link to start downloading the files which makes them independent from torrent indexers. It also allows them to distribute the information more easily. Torrent indexers remain on the other hand the main source of information for new files that are available for download.

Magnet Links use DHT

A tracker less environment should raise a question of identification. How can a download be initiated ff there is no tracker to inform the Bittorrent user about other users who download and seed the file? The answer is DHT, Distributed hash tables. DHT is enabled by default in popular clients such as uTorrent or Vuze. Without going into to much detail, the hash of the magnet link is used to find peers using DHT.

Torrent files

Torrents are still essential for Bittorrent as they contain information about the download that need to be present in the swarm. The only aspect that is changing is the way the torrents are distributed which is shifting from Bittorrent trackers and indexers to the server-less DHT procedure.
