i am reading lately a lot about hash from torrents an magnetic links etc.
It checks the integrity of downloaded data, also used to check whether data is corrupted or not. Each data (may be in pieces) has a hash associated with it. After downloading the hash of downloaded data is calculated and checked with info hash of torrent. If they match then it is integrity is maintained and it is not corrupted. Well, that data you downloaded (torrented ? ) didn’t match the expectations and just got discarded.Actually the torrent you download is divided into multiple pieces and you download data piece by piece. Every piece which is downloaded goes under ‘hash checking’ – a technique which will find for errors in piece. Jul 9, 2014 - Torrents have an info_hash or and torrent hash that represents the. So today I will show you how to download files using info_hash just in.

So I finally figured it out.
Torrent Hash To Magnet
The “infohash” is the SHA1 Hash over the part of a torrent file that includes:
- ITEM: length(size) and path (path with filename)
- Name: The name to search for
- Piece length: The length(size) of a single piece
- Pieces: SHA1 Hash of EVERY piece of this torrent
- Private: flag for restricted access
To show this a little more I took a random torrent file and used the “BEncode Editor” from Ultima to make it more clearly to me.
As you can see the the red box marked the information part of the torrent file.The torrent file includes not the Hash of the items, but the hashes of every piece.
- For item1 with: 1069496548
- and item2 with: 223
- It is together: 1069496771
- With a piece size of: 524288
- There are 2040 pieces. (1069496771/524288=2039.9032 approximately)
- The pieces section includes 40800 byte of data what are 81600 + 2 chars in the file.
- the +2 because 0x marks that this is hexadecimal.
- A SHA1 hash has 40 0x chars or 20 Byte of data what are 2040 SHA1 hashes.
I am sorry that this information is about a torrent that leads to a illegal movie, but i wanted to use a torrent that realy exists.
