torrent-client

Tiny BitTorrent client written in Go. Uses SCION under the hood with the pathdiscovery libary.

Install

go get github.com/martenwallewein/torrent-client

Usage

To use this Bittorrent client (at the moment, SCION usage is mandatory. We will support also TCP in the future), you need to have at least a SCION endhost (or a full SCION AS) running. The easiest way is to join SCIONLab and create a user-AS.

Furthermore, you need valid TLS certificates (used by quic-go). To create these, use: openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes

Run a seeder

SCION_CERT_KEY_FILE=key.pem SCION_CERT_FILE=cert.pem ./torrent-client -inPath='5G_1.torrent' -outPath='5G.file' -peer="19-ffaa:1:111,[127.0.0.1]:43000" -seed=true -file=5G.file -local="19-ffaa:1:000,[127.0.0.1]:46000"

Run a leecher

SCION_CERT_KEY_FILE=key.pem SCION_CERT_FILE=cert.pem ./torrent-client -inPath='5G_1.torrent' -outPath='ubuntu.file' -peer="19-ffaa:1:c3f,[127.0.0.1]:43000" -seed=false -file='5G.file' -local="19-ffaa:1:111,[127.0.0.1]:43000"
