The values may be any bencoded type, including integers, strings, lists, and other dictionaries. Note that the keys must be bencoded strings. The initial d and trailing e are the beginning and ending delimiters. Lists may contain any bencoded type, including integers, strings, dictionaries, and even lists within other lists.Įxample: l4:spam4:eggs e represents the list of two strings: Įxample: le represents an empty list: Dictionaries The initial l and trailing e are beginning and ending delimiters.
NOTE: The maximum number of bit of this integer is unspecified, but to handle it as a signed 64bit integer is mandatory to handle "large files" aka. All encodings with a leading zero, such as i03 e, are invalid, other than i0 e, which of course corresponds to the integer "0". The initial i and trailing e are beginning and ending delimiters.Įxample: i3 e represents the integer "3" Example: i-3 e represents the integer "-3" Note that there is no constant beginning delimiter, and no ending delimiter.Įxample: 4: spam represents the string "spam"Įxample: 0: represents the empty string "" Integers It supports the following types: byte strings, integers, lists, and dictionaries. one-line) entry for each major change that you've made to the document.īencoding is a way to specify and organize data in a terse format.

Two or more blocks make up a whole piece, which may then be verified. A block is a portion of data that a client may request from a peer. piece v/s block: In this document, a piece refers to a portion of the downloaded data that is described in the metainfo file, which can be verified by a SHA1 hash. Readers of this specification may choose to think of themselves as the client which connects to numerous peers. The client is also a peer, however it is the BitTorrent client that is running on the local machine. peer v/s client: In this document, a peer is any BitTorrent client participating in a download. In this document, a number of conventions are used in an attempt to present information in a concise and unambiguous fashion. As newer revisions of each protocol are defined, they should be specified on their own separate pages, not here. UTORRENT 1.8.7 HAMMERING TRACKER TORRENT
Currently, this applies to the torrent file structure, peer wire protocol, and the Tracker HTTP/HTTPS protocol specifications. version 1.0) of the BitTorrent protocol specification.
This document applies to the first version (i.e. This is not the place to suggest feature requests. Everyone is invited to contribute to this document, with the understanding that the content here is intended to represent the current protocol, which is already deployed in a number of existing client implementations.
This document is intended to be maintained and used by the BitTorrent development community. The hope is that this document will become a formal specification, written in clear, unambiguous terms, which can be used as a basis for discussion and implementation in the future. Bram's protocol specification page outlines the protocol in somewhat general terms, and lacks behaviorial detail in some areas. The purpose of this specification is to document version 1.0 of the BitTorrent protocol specification in detail. Visit his pages at BitTorrent is designed to facilitate file transfers among multiple peers across unreliable networks. 13.5 BitTorrent Location-aware Protocol 1.0īitTorrent is a peer-to-peer file sharing protocol designed by Bram Cohen.13 Unofficial Extensions To The Protocol.
