The downloaded parts arrive in small chunks from dozens of different users, then your computer pieces them back together again to make a single, usable file. Because the file your downloading is so fragmented, there needs to be a reliable way to verify the contents. Otherwise, how does your torrent client know which bits to download from the P2P network? This is where the info hash comes in.
It is best thought of as a unique ID for the torrent you are downloading. It is identical for all users and across all trackers. An info hash uses an SHA-1 cryptographic hash. SHA-1 hashes are 40 digits long though you will also come across types of info hashes that are 32 or 64 digits. The hash is created by gathering specific informationsuch as file size, path, name, piece length, piece hashes, and privacy flags, then running it through a mathematical algorithm.
If you're technically minded, you can also use the info hash to bypass centralized torrent trackers and communicate directly with peers via a Distributed Hash Table DHT. There are two ways to add a file to your torrent client. A magnet link takes a more simplified approach. It's a hyperlink that contains the torrent hash. As such, your client doesn't need to make its own hashit can immediately start looking for files on the DHT.
You also don't need to download any files onto your hard drive before you start downloading; a magnet file will open directly in your torrent client. On a more practical level, magnet files also lead to more successful downloads. They are not affected if trackers are out-of-service or closed for registration. Several online tools will let you convert an info hash to magnet files. They are useful if you want to create your own torrent or someone has a shared a torrent hash with you.
The Romanr. Just paste the info hash in the first text field, give the torrent a name if desired , and hit Generate. For a greater level of control, you can choose which trackers to include. HashtoMagnet is a spin-off from the once-popular but now defunct Hash2Magnet tool. The site has two features. Firstly, you can perform a hash to magnet conversion. To do so, you just need the info hash code.
Secondly, you can check the current seeder, leecher, and completed status for any torrent. It scans dozens of trackers and might help you bring a dead torrent back to life. Developer Daniel Aleksandersen has created a hash to magnet converter on his website. The tool does not have an official name, but it works just as well as the other converters we've looked at.
There are no fancy customizations like selectable trackers or torrent names. For example, if you use Pirate Bay, type in the name of the desired file in the search field.
Then select it from the search results. You can also see the info hash after you start downloading the file. In case you ever need to provide someone with this code, you can find it in uTorrent instead of looking it up all over again.
Another way is to use the info hash to generate a magnet link to download the torrent. The info hash contains all the relevant torrent info and content: its name, and other data necessary to download it.
