In the BitTorrent file distribution system, a torrent file or meta-info file is a computer file that contains metadata about files and folders to be distributed, and usually also a list of the network locations of trackers, which are computers that help participants in the system find each other and form efficient distribution groups called swarms. A torrent file does not contain the content to be distributed; it only contains information about those files, such as their names, folder structure, sizes, and cryptographic hash values for verifying file integrity. Torrent files are normally named with the extension ".torrent".
A torrent file acts like a table of contents (index) that allows computers to find information through the use of a BitTorrent client. With the help of a torrent file, one can download small parts of the original file from computers that have already downloaded it. These "peers" allow for downloading of the file in addition to, or in place of, the primary server.
The BitTorrent system has been created to ease the load on central servers, as instead of having individual clients fetch files from the server, BitTorrent can crowd-source the bandwidth needed for the file transfer and reduce the time needed to download large files. Many free/freeware programs and operating systems, such as the various Linux distributions offer a torrent download option for users seeking the aforementioned benefits. Other large downloads, such as media files, are often torrented as well.
Typically, Internet access is asymmetrical, supporting greater download speeds than upload speeds, limiting the bandwidth of each download, and sometimes enforcing bandwidth caps and periods where systems are not accessible. This creates inefficiency when many people want to obtain the same set of files from a single source; the source must always be online and must have massive outbound bandwidth. The BitTorrent protocol addresses this by decentralizing the distribution, leveraging the ability of people to network "peer-to-peer", among themselves.
Each file to be distributed is divided into small information chunks called pieces. Downloading peers achieve high download speeds by requesting multiple pieces from different computers simultaneously in the swarm. Once obtained, these pieces are usually immediately made available for download by others in the swarm. In this way, the burden on the network is spread among the downloaders, rather than concentrating at a central distribution hub or cluster. As long as all the pieces are available, peers (downloaders and uploaders) can come and go; no one peer needs to have all the chunks or to even stay connected to the swarm in order for distribution to continue among the other peers.
A small torrent file is created to represent a file or folder to be shared. The torrent file acts as the key to initiating downloading of the actual content. Someone interested in receiving the shared file or folder first obtains the corresponding torrent file, either by directly downloading it or by using a magnet link. The user then opens that file in a BitTorrent client, which automates the rest of the process. In order to learn the internet locations of peers who may be sharing pieces, the client connects to the trackers named in the torrent file, and/or achieves a similar result through the use of distributed hash tables. Then the client connects directly to the peers in order to request pieces and otherwise participate in a swarm. The client may also report progress to trackers, to help the tracker with its peer recommendations.
The new format uses SHA-256 in both the piece-hashing and the infohash, replacing the broken SHA-1 hash. The "btmh" magnet link would contain the full 32-byte hash, while communication with trackers and on the DHT uses the 20-byte truncated version to fit into the old message structure. It is possible to construct a torrent file with only updated new fields for a "v2" torrent, or with both the old and new fields for a "hybrid" format. However, as a torrent would have different infohashes in v1 and v2 networks, two swarms would form, requiring special handling by the client to merge the two. In addition, as v2 adds keys to info, there can be no 
A core feature of the new format is its application of merkle trees, allowing for 16KiB blocks of a piece to be individually verified and re-downloaded. Each file now always occupy whole piece sizes and have an independent merkle root hash, so that it's possible to find duplicate files across unrelated torrent files of any piece length. The file size is not reduced, but the info dictionary required for magnet links are (only in v2-only torrents).
A torrent file can also contain additional metadata defined in extensions to the BitTorrent specification. These are known as "BitTorrent Enhancement Proposals." Examples of such proposals include metadata for stating who created the torrent, and when.
BEP-0030 extends BitTorrent to support Merkle trees (originally implemented in Tribler). The purpose is to reduce the file size of torrent files, which reduces the burden on those that serve torrent files.

Torrent sites allow users to leave comments, and checking them is another quick way to figure out whether a seed is malevolent. Good-quality torrents are typically praised by other downloaders, too, so it quickly becomes clear which ones are worth your time.
Having reliable antivirus software is just good practice when surfing the web. Hackers like to hide malware inside of torrent downloads, easily infecting the users who download them. Cybercriminals understand that hiding malware in a torrent file can allow them to infect huge numbers of people, and this is just about the easiest way to force exploits onto victims.
Trojans, on the other hand, let the hacker commandeer your device's microphone or camera to snoop on you, steal the data in your phone, install keyloggers to steal your passwords and financial information, and steal all your files, photos, and contacts.
Trojans are often downloaded by unwitting people torrenting computer programs, as the user is attempting to download an executable (.exe) file. In this format, it's easy to swap out the expected program with a virus, making the potential ramifications of downloading from torrent sites quite scary.
Avoiding .exe and .bat files entirely is difficult, even if it is recommended to steer clear from them where possible. Fortunately, you can usually spot fake installers by checking the size of the download against the size of the genuine installer. Preferably it should be identical, but there can be some variances depending on the version or upload. If the difference is noticeable, however, this is a sign that the file is probably not what you wanted.
Checking file sizes is not a foolproof method of spotting an infected torrent file. Hackers are getting smarter by the day. For total protection, you need a reliable and up to date antivirus and anti-malware program. To help, we have listed some recommended antivirus programmes that you can use when torrenting.
This is an elevated security precaution that most people will probably not need to take. However, if you often download executable files (computer programs) from torrent repositories, then it's a good idea to protect yourself in this way.
Downloading files to a sandbox environment ensures that malicious files will not infect your entire machine if you accidentally download a virus or malware. You can then check the file is legit before installing it onto your main machine. Sandboxie is a great tool that allows you to create a sandboxed environment on your PC.
Alternatively, you may prefer to install a full Virtual Machine (using Parallels or VirtualBox, for example) and check the file there first. To do so, simply download the torrent onto your VM, use VirusTotal to scan the file, and if VirusTotal gives it the all-clear, then run the file in the VM to make sure it is ok. If the file is clean, and the installer works fine in the VM, you are fine to move the program over onto your real operating system.
If you do manage to get an invitation to one of these clubs, you'll be in an environment where you can trust the quality of the torrents. This will make you far less likely to come across malicious files, viruses, malware, spam, and Trojans.
It is worth bearing in mind that once you do manage to join a closed-door community, there will be certain rules. Most of them require you to maintain an up/down ratio, so you will need to upload data as well as download it, helping other members of the community by seeding the downloads they want.
Most communities demand that you maintain at least a 1:1 ratio, which is where you download the same amount as you upload. Admittedly, when you join a new community, it can be hard to manage this instantly. The good news is that all new users are given a grace period to achieve this equilibrium.
When you do sort out your ratio, you will be far less likely to get booted from the community. So, if you are failing to sort out your ratio, you may want to consider giving a donation to the community (for the cost of servers, etc). However, maintaining a good ratio is better, and will even gain you perks such as VIP status and an upgraded account on the tracker with faster download speeds.
To the same ends, it is a good idea to download newly released torrents quickly; if you are one of the first to download, you are more likely to have success in seeding them back to other community members. Also, be sure to steer away from zero leech torrents, you want popular files that other people want to download; as this will help you to achieve your 1:1 ratio. 781b155fdc
