about

nx_torrent_mkinfo.nx -- BUILD a BEP-3 v1 single-file torrent info-dict from a REAL file. The seeder (nx_torrent_seed) can serve any file, but a REAL leecher can only find + verify it if it has the file's v1 info_hash and per-piece SHA-1s -- i.e. a .torrent/magnet. nx_metainfo only PARSES a .torrent; this is the inverse (the "originate/create a torrent" half): read a file, SHA-1 each piece, bencode the info-dict (length/name/piece length/pieces, keys sorted per BEP-3), SHA-1 it -> info_hash, and emit a magnet + a seed_index.conf row. This is what lets the hub SHARE content that any mainstream BitTorrent client (qBittorrent/Transmission/libtorrent) can pull + integrity-check. nx_torrent_mkinfo <file> <name> [piece_length] -> info_hash / magnet / seed row (default plen=262144) nx_torrent_mkinfo -> no-arg = the GATE (round-trips through nx_metainfo) NEVER-BRICK: reads a file + prints; writes no persistent state. license_tier: ORIGINAL module: nishi-core.torrent.mkinfo depends: nishi-core.torrent.metainfo (pulls bencode+sha1+syscalls)
