go-torrent.mov
This project is a partial implementation of the BitTorrent protocol. Given a torrent file, go-torrent is able to find peers and download the associated files piece by piece. This was intended as a way to more deeply understand a protocol I've always been curious about.
The client supports HTTP and UDP trackers, multi-file torrents, and the ability to pause and resume downloads. At the moment, it only leeches - that is, it doesn't support uploading pieces - but this is something I would like to revisit at some point in the future.
To initiate a download:
go run main.go --file ./path/to/my/torrent
You can also pass a debug flag to see the requests being made under the hood.
