Tool to decode and encode .torrent files

bcoder

About

---

A Python package to handle bencoded values, a serialization format commonly used in .torrent files within the BitTorrent protocol.

Usage

---

There are 2 types of classes:

• BDecoder - handle decoding of bencoded data to common Python types
• BEncoder - handle encoding of common Python types to bytes type

Example of BDecoder usage:

from bcoder import BDecoder

decoder = BDecoder()

with open("file.torrent", "rb") as file:
    data = file.read()

decoded = decoder.decode(data)

Example of BEncoder usage:

from bcoder import BEncoder

encoder = BEncoder()

data = {
    b"announce-list": [
        [b"udp:..."],
        [b"udp:..."],
    ],
    b"info": {
        b"piece": b"xfsasf",
        b"piece length": 123,
    },
}

encoded = encoder.encode(data)

NOTE: BEncoder is spec-strict (BEP 3). Only bytes, int, list, and dict with bytes keys are accepted. Pass str through .encode("utf-8") yourself if you need to encode text.
