Bittorrent encoding in ruby
BEncoder will encode the 4 data types in the specification:
- Strings
- Integers
- Arrays
- Hashes
Additionally, it will pass symbols as strings, to allow for easier hash convertion.
install with
gem install bencoder Usage is easy:
BEncoder.encode"herp"=>"4:herp"BEncoder.decode"4:herp"=>"herp"BEncoder.encode['what','strange',{data: 'I',have: 'here'},666]=>"l4:what7:stranged4:data1:I4:have4:hereei666ee"BEncoder.decode'l4:what7:stranged4:data1:I4:have4:hereei666ee'=>['what','strange',{'data'=>'I','have'=>'here'},666]Since .torrent files are bencode dicts, you can parse them out of the box
BEncoder.decodeFile.read('sample.torrent')=>{"announce"=>"udp://tracker.openbittorrent.com:80","creation date"=>1327049827,"info"=>{"length"=>20,"name"=>"sample.txt","piece length"=>65536,"pieces"=>"\\\xC5\xE6R\xBE\r\xE6\xF2x\x05\xB3\x04d\xFF\x9B\x00\xF4\x89\xF0\xC9","private"=>1}}
