A tool to download Torrent metadata from info-hashes that have been captured by listening to the DHT.
The process is quite simple, you can listen to the DHT in a number of ways, in example by applying a small patch to qBittorrent or using Dodder (or my clone https://github.com/itlezy/LezyDodder ).
Once you have obtained a list of hashes, you can load them in a MongoDB for ease of processing. The tool here would read hashes from MongoDB and attempt to download their metadata directly from the DHT and saving to a file.
A feature to listen to the DHT get_peers and announce_peer to potentially find new torrents hashes, download their metadata and show them in the qBittorrent interface.
As we are already active nodes in the DHT you can activate the DHT alerts
void Session::initializeNativeSession()
{
const lt::alert_category_t alertMask = lt::alert::error_notification
| lt::alert::dht_notificationand capture hashes that are queried around the DHT
void Session::handleDHTAnnounceAlert(const lt::dht_announce_alert* p)
{
const lt::sha1_hash infoHash = p->info_hash;
const QByteArray raw = QByteArray::fromRawData(infoHash.data(), infoHash.size());
LogMsg(tr("handleDHTAnnounceAlert \"%1\"").arg(QString::fromLatin1(raw.toHex())), Log::INFO);
}
void Session::handleDHTGetPeersAlert(const lt::dht_get_peers_alert* p)
{
const lt::sha1_hash infoHash = p->info_hash;
const QByteArray raw = QByteArray::fromRawData(infoHash.data(), infoHash.size());
LogMsg(tr("handleDHTGetPeersAlert \"%1\"").arg(QString::fromLatin1(raw.toHex())), Log::INFO);
}
