Hello,

I tried creating a .torrent file in I2P Snark and decided to check the file for metadata using MAT (metadata anonymization tool). It actually checked the file as "dirty" and cleaned it, but afterwards the file didn't work in I2P Snark anymore. So my question is how revealing is metadata and if we can trust a .torrent file? Also does anyone knows if I2P Snark actually does something different with it's torrent files in order to ensure privacy?

Thanks.

Thanks for the replies. What I still didn't understand was what metadata is present in .torrent files. Any info? Thanks.

mat2 allows to remove metadata from files, including torrent files: https://0xacab.org/jvoisin/mat2

There is a Web version too: https://0xacab.org/jvoisin/mat2-web

And a demo (with the relevant note: "while we do not keep a copy of your image, there is no way that you could be certain about this: act accordingly."): https://mat2-web.dustri.org/

I tried to upload there some torrent files. "Just for fun, those are the metadata that mat2 detected in your file, before cleanup", mat2 writes. Nothing particularly revealing, apparently. E.g.:
magnet-info: {b'info_hash': b'\xb0\x06.\xa9\xc0\t\x01\x7f\xfe\xa4S\xf6\x83P\x8e\xeb\xb4\xdc\x0b\xd8', b'display-name': b'citizenfour+2014+720p+web+dl+850mb+mkvcage'}

Thanks.
As I said in the original post, I already tried using MAT to clean the .torrent files. However they stopped working. That was my point. Your reply actually gave me info about WHAT is inside the files. Thanks, I feel more comfortable now.
