Exemple des détails de la partie XT

URN, containing hash (xt)

"xt" ("exact topic"): the most important part of a Magnet link, this parameter is used to find and verify the specified files.

TTH (Tiger Tree Hash)

These hashes are used on Direct Connect and G2 (Gnutella2), among others.

   xt=urn:tree:tiger:[ TTH Hash (Base32) ]

SHA-1 (Secure Hash Algorithm 1)

These hash sums are used on gnutella and G2 (Gnutella2).

   xt=urn:sha1:[ SHA-1 Hash (Base32) ]

BitPrint

Such hash sums consist of an SHA-1 Hash, followed by a TTH Hash, delimited by a point; they are used on gnutella and G2 (Gnutella2).

   xt=urn:bitprint:[ SHA-1 Hash (Base32) ].[ TTH Hash (Base32) ]

ED2K (eDonkey2000) Hash

These hash sums are used on eDonkey2000.

   xt=urn:ed2k:[ ED2K Hash (Hex) ]

AICH (Advanced Intelligent Corruption Handler)

Not formal URNs for Magnet links, such hash sums are used by eDonkey2000 to restore and control the integrity of downloading and already downloaded files.

   xt=urn:aich:[ aich Hash (Base32) ]

Kazaa Hash

Used on FastTrack, these hash sums are vulnerable to hash collision attacks.

   xt=urn:kzhash:[ Kazaa Hash (Hex) ]

BTIH (BitTorrent Info Hash)

These are hex encoded SHA-1 hash sums of the "info" sections of BitTorrent metafiles as used by BitTorrent to identify downloadable files or sets of files. For backwards compatibility with existing links, clients should also support the Base32 encoded version of the hash.[1]

   xt=urn:btih:[ BitTorrent Info Hash (Hex) ]

Some clients require Base32 of info_hash (Vuze for ex.).

MD5 (Message Digest 5)

Supported by G2 (Gnutella Peanut Butter), such hashes are vulnerable to hash collision attacks.

   xt=urn:md5:[ MD5 Hash (Hex) ]
