- The file accommodates an inventory of torrent trackers (if any) that coordinate all of the friends taking part within the torrent.
- It accommodates details about the information which can be being shared, akin to their names, sizes, and knowledge wanted to do integrity checks on the information.

In essence, a magnet hyperlink is just a string of textual content. Nevertheless, there’s loads of info packed into that string!
A magnet hyperlink accommodates a novel identifier, varied parameters relying on the precise nature of the torrent, and, most significantly, a cryptographic hash of the torrent information.
A cryptographic hash is a mathematical algorithm utilized to knowledge that ends in a brief distinctive string that represents that knowledge. That is helpful for torrents as a result of you’ll be able to hash any two torrents and in the event that they level to precisely the identical information, they may have similar hashes.
So, in your torrent consumer to know who else is a part of a given torrent, it merely has to match the hash within the magnet hyperlink to the hashes of torrents which can be being shared. Filtering out solely these with matching hashes rapidly reconstructs the swarm of friends on the community. This is similar methodology utilized by the Distributed Hash Desk discovered inside “trackerless” torrents. These are torrents that don’t make use of a central server to coordinate friends and maintain observe of friends.
A magnet hyperlink strips out solely this important info and does away with the remainder of the torrent file, because the overwhelming majority of individuals within the torrent don’t want that info.
