Magnet URI hash is SHA1. A hash collision can still be used as an attack if you create 2 torrents with the same hash and then distribute.

- koolba 10y agoThat's not an issue with the torrents. It's an issue with the magnet URI format for referncing torrents. The "good" torrent would not be susceptible to attack via this receiving the entire torrent file directly (say over HTTPS) is fine.

- koolba 10y agoLooks like it's time to update the magnet link format to use a newer hash.
