Python 3 module for creating and parsing torrent files and magnet URIs

Project description

torf provides a Torrent and a Magnet class.

torf-cli and torf-gui provide user interfaces for torf.

This project started as a fork of dottorrent but turned into a rewrite.


  • Create a Torrent instance from a path to the torrent’s content or by reading an existing .torrent file

  • High-level access to standard metainfo fields via properties

  • Low-level access to arbitrary metainfo fields via metainfo property

  • Optional metainfo validation with helpful error messages

  • Generate a BTIH magnet URI from a .torrent file (the reverse is also possible but the resulting torrent is incomplete due to the lack of information in magnet URIs)

  • Use multiple CPU cores to compute piece hashes

  • Randomize the info hash to help with cross-seeding

  • Conveniently re-use piece hashes from an existing torrent file


from torf import Torrent
t = Torrent(path='path/to/content',
            comment='This is a comment')
t.private = True


Everything should be explained in the docstrings. Read it with pydoc3 torf.Torrent or pydoc3 torf.Magnet.

Documentation is also available at or for the development version.


torf is available on PyPI.

The latest development version is in the master branch on GitHub.


I consider this project feature complete, but feel free to request new features or improvements. Bug reports are always welcome, of course.
