Presenteras<\/a><\/noindex> betydande utgivning av biblioteket libtorrent 2.0<\/a><\/noindex> (\u00e4ven k\u00e4nd som libtorrent-rasterbar), erbjuder en implementation av BitTorrent-protokollet, effektiv n\u00e4r det g\u00e4ller minnesanv\u00e4ndning och CPU-belastning. Biblioteket anv\u00e4nds<\/a><\/noindex> i s\u00e5dana torrentklienter som Deluge<\/a><\/noindex>, qBittorrent<\/a><\/noindex>, Folx<\/a><\/noindex>, Lince<\/a><\/noindex>, Miro<\/a><\/noindex> och Flush<\/a><\/noindex> (f\u00f6rv\u00e4xla inte med ett annat bibliotek libtorrent<\/a><\/noindex>, som anv\u00e4nds i rTorrent). Koden f\u00f6r libtorrent \u00e4r skriven i C++ och sprids<\/a><\/noindex> under BSD-licensen.<\/p>\n

Utgivningen k\u00e4nnetecknas av till\u00e4gget av<\/a><\/noindex> st\u00f6d f\u00f6r protokollet BitTorrent v2<\/a><\/noindex>, d\u00e4r \u00f6verg\u00e5ngen fr\u00e5n att anv\u00e4nda algoritmen SHA-1, som har problem<\/a><\/noindex> med kollisionshantering, till f\u00f6rm\u00e5n f\u00f6r SHA2-256. SHA2-256 anv\u00e4nds b\u00e5de f\u00f6r att kontrollera integriteten av datablock och f\u00f6r poster i index (info-dictionary), vilket bryter kompatibiliteten med DHT och trackers. F\u00f6r magnetl\u00e4nkar till torrents med hashv\u00e4rden i SHA2-256 f\u00f6resl\u00e5s ett nytt prefix «urn:btmh:» (f\u00f6r SHA-1 och hybrid torrents anv\u00e4nds «urn:btih:»).<\/p>\n

Eftersom ers\u00e4ttningen av hash-funktionen bryter kompatibiliteten med protokollet (f\u00e4ltet med 32-byte hash ist\u00e4llet f\u00f6r 20-byte) har utvecklingen av BitTorrent v2-specifikationen fr\u00e5n b\u00f6rjan gjorts utan h\u00e4nsyn till bak\u00e5tkompatibilitet och andra betydande f\u00f6r\u00e4ndringar har inf\u00f6rlivats, s\u00e5som anv\u00e4ndning av Merkle-tr\u00e4d i index f\u00f6r att minska storleken p\u00e5 torrent-filer och kontrollera nedladdad data p\u00e5 blockniv\u00e5.<\/p>\n

Bland f\u00f6r\u00e4ndringarna i BitTorrent v2 framh\u00e4vs \u00e4ven \u00f6verg\u00e5ngen till att knyta separata hash-tr\u00e4d till varje fil och till\u00e4mpningen av filjustering i delar (utan att l\u00e4gga till extra fyllnad efter varje fil), vilket eliminerar duplicering av data i fall av identiska filer och f\u00f6renklar identifieringen av olika k\u00e4llor f\u00f6r filer. Effektiviteten av katalogstrukturen i torrenter har f\u00f6rb\u00e4ttrats och optimeringar f\u00f6r hantering av m\u00e5nga sm\u00e5 filer har lagts till. <\/p>\n

F\u00f6r att underl\u00e4tta samexistensen av BitTorrent v1 och BitTorrent v2 har m\u00f6jligheten att skapa hybrida torrent-filer genomf\u00f6rts, som inkluderar f\u00f6rutom strukturer med SHA-1-hashar, index med SHA2-256.
\nDessa hybrida torrenter kan anv\u00e4ndas med klienter som endast st\u00f6der protokollet BitTorrent v1. Den f\u00f6rv\u00e4ntade st\u00f6d i libtorrent 2.0 f\u00f6r WebTorrent-protokollet p\u00e5 grund av ol\u00f6sta stabilitetsproblem \u00e4r f\u00f6rdr\u00f6jd<\/a><\/noindex> fram till n\u00e4sta betydande utgivning, som inte kommer att lanseras f\u00f6rr\u00e4n i slutet av \u00e5ret. <\/p>\n
