file hashes are signed / secure enough

[recover-sanity]

It would be great to revisit this as Bittorrent V2 has other benefits besides switching from SHA1, like more efficient hashing and the ability to share peers of different torrents if the file hashes are the same (example: User downloads vXX.0.1 and can download binaryfate.asc from peers seeding vXX.0.0). Hybrid torrents are both a v1 and v2 torrent for backwards compatibility, allowing users with clients supporting only v1 to download and seed, though not all trackers support them sadly.

thanks for taking a look at the repo and issues @recover-sanity, i switched to mktorrent after i noticed that is what the torrent @ https://bitcoin.org/en/download is created with, small and easy to compile with make and create a torrent. didnt come with v2 but i see this issue from 2019 which links some other projects that support v2 pobrn/mktorrent#29

[recover-sanity]

Seems like torrenttools supports v2/hybrid torrents. Requires more dependencies to build though.
