<h2 id="history">History</h2> <p>The standard for Magnet <a href="/facts/Uniform_Resource_Identifier/UjyqxTpA">URIs</a> was developed by <a href="/facts/Bitzi/uK8Y6m8t">Bitzi</a> in 2002, partly as a "vendor- and project-neutral generalization" of the ed2k: and freenet: URI schemes used by <a href="/facts/EDonkey2000/VyJlegGg">eDonkey2000</a> and <a href="/facts/Freenet/VrRhhcDc">Freenet</a> (now Hyphanet), respectively, and attempts to follow official <a href="/facts/Internet_Engineering_Task_Force/tIcCsFhX">IETF</a> <a href="/facts/Uniform_Resource_Identifier/UjyqxTpA">URI</a> standards as closely as possible. <a href="/facts/BitTorrent/HP9ChWWW">BitTorrent</a> introduced the btmh: protocol in 2020 as part of its BitTorrent v2 changes.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a> </p> <h2 id="format">Format </h2> <p>Magnet URIs consist of a series of one or more parameters, the order of which is not significant, formatted in the same way as <a href="/facts/Query_string/nUTW9ITa">query strings</a> that ordinarily terminate <a href="/facts/HTTP/TWtvf7JD">HTTP</a> URLs. </p><p>The following parameters are supported:<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a><a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> </p> <table><tbody><tr><th>Parameter</th><th>Name</th><th>Description</th></tr><tr><td>xt</td><td>eXact Topic</td><td><a href="/facts/Uniform_Resource_Name/DCaGkLLY">URN</a> containing file <a href="/facts/Hash_sum/rk6MlCt3">hash</a>.

Its purpose is to provide a search parameter for finding the metadata to the torrent. This effectively acts as a replacement to a .torrent file, which itself contains the torrent metadata, by instead searching the p2p network (using the URN) for that metadata. Each protocol handles a URN uniquely; for example, xt=urn:btih:FFC7E738EAA4CD4ECF51EC6FD669C6CDE2C281A8 uses the btih (BitTorrent v1 protocol), so a BitTorrent client can take the hash and lookup the torrent's metadata in the BitTorrent DHT.<a class="footnote-ref" id="fnref:9" href="#fn:9"><sup>9</sup></a> In the case of DHT the client searches through a set of pre-known nodes and requests the metadata for an infohash; those nodes will make the same request to other known nodes until eventually a swarm is found and returned. </p><p>xt also allows for a group setting. Multiple files can be included by adding a count number preceded by a dot (".") to each link parameter. </p> magnet:?xt.1=[ <a href="/facts/Uniform_Resource_Name/DCaGkLLY">URN</a> of the first file]&xt.2=[ URN of the second file] <a href="/facts/Merkle_tree/uGFY5mNA">Tiger Tree Hash</a> (TTH) These hashes are used on <a href="/facts/Direct_Connect_(file_sharing)/wzeg0qxc">Direct Connect</a> and <a href="/facts/Gnutella2/5okK5h5W">G2</a> (Gnutella2), among others. xt=urn:tree:tiger:[ <a href="/facts/Merkle_tree/uGFY5mNA">TTH</a> <a href="/facts/Hash_sum/rk6MlCt3">Hash</a> (<a href="/facts/Base32/JVDAnQyn">Base32</a>) ] <a href="/facts/SHA-1/LDYCV1je">Secure Hash Algorithm 1</a> (SHA-1) These hash sums are used on <a href="/facts/Gnutella/canem2yq">gnutella</a> and <a href="/facts/Gnutella2/5okK5h5W">G2</a> (Gnutella2). xt=urn:sha1:[ <a href="/facts/SHA-1/LDYCV1je">SHA-1</a> <a href="/facts/Hash_function/rk6MlCt3">Hash</a> (<a href="/facts/Base32/JVDAnQyn">Base32</a>) ] BitPrint Such hash sums consist of an SHA-1 Hash, followed by a TTH Hash, delimited by a point; they are used on <a href="/facts/Gnutella/canem2yq">gnutella</a> and <a href="/facts/Gnutella2/5okK5h5W">G2</a> (Gnutella2). xt=urn:bitprint:[ <a href="/facts/SHA-1/LDYCV1je">SHA-1</a> <a href="/facts/Hash_function/rk6MlCt3">Hash</a> (<a href="/facts/Base32/JVDAnQyn">Base32</a>) ].[ <a href="/facts/Merkle_tree/uGFY5mNA">TTH</a> <a href="/facts/Hash_sum/rk6MlCt3">Hash</a> (<a href="/facts/Base32/JVDAnQyn">Base32</a>) ] <a href="/facts/EDonkey_network/BT49PwbE">ED2K</a> (eDonkey2000) hash These hash sums are used on <a href="/facts/EDonkey_network/BT49PwbE">eDonkey2000</a>. xt=urn:ed2k:[ <a href="/facts/EDonkey_network/BT49PwbE">ED2K</a> <a href="/facts/Hash_sum/rk6MlCt3">Hash</a> (<a href="/facts/Hexadecimal/02ohQW22">Hex</a>) ] <a href="/facts/AICH/et19fF6x">Advanced Intelligent Corruption Handler</a> (AICH) Not formal URNs for Magnet links, such hash sums are used by <a href="/facts/EDonkey_network/BT49PwbE">eDonkey2000</a> to restore and control the integrity of downloading and already downloaded files. xt=urn:aich:[ <a href="/facts/AICH/et19fF6x">aich</a> <a href="/facts/Hash_sum/rk6MlCt3">Hash</a> (<a href="/facts/Base32/JVDAnQyn">Base32</a>) ] <a href="/facts/Kazaa/nTWC7AkU">Kazaa</a> hash Used on <a href="/facts/FastTrack/tssQtDN9">FastTrack</a>, these hash sums are vulnerable to <a href="/facts/Collision_attack/6aXFAMbW">hash collision attacks</a>. xt=urn:kzhash:[ <a href="/facts/Kazaa/nTWC7AkU">Kazaa</a> <a href="/facts/Hash_sum/rk6MlCt3">Hash</a> (<a href="/facts/Hexadecimal/02ohQW22">Hex</a>) ] BitTorrent info hash (BTIH) These are hex-encoded <a href="/facts/SHA-1/LDYCV1je">SHA-1</a> hash sums of the "info" sections of <a href="/facts/BitTorrent_(protocol)/HP9ChWWW">BitTorrent metafiles</a> as used by <a href="/facts/BitTorrent_(protocol)/HP9ChWWW">BitTorrent</a> to identify downloadable files or sets of files.
