Net::BitTorrent::VersiUser)Contributed Perl DocumenNet::BitTorrent::Version(3)

       Net::BitTorrent::Version	- Net::BitTorrent's project-wide version

       Because of the problems coordinating revision numbers in	a distributed
       version control system and across a directory full of Perl modules,
       this module provides a central location for the project's overall
       release number, the version string provided in Extended Protocol
       handshakes, and the Peer	ID generator.

   "gen_node_id	( )"
       Returns a random	20-byte	string that can	be used	to identify ourself in
       a DHT swarm.

   "gen_peerid ( )"
       Generates a unique Peer ID based	on Net::BitTorrent's Specification.

Peer ID	Specification
       This section describes and provides examples of the Peer	ID format used
       by this release of the "Net::BitTorrent"	module.

       This non-standard format	was developed to be URL-safe, unique to	the
       implementation, and "human parsable."

       There are two distinct sections to the Peer IDs generated: the header
       which may be used to identify the software and its version, and the
       signature which is... well, it's	junk.  Consider	this example:


       Here, "NB004S" is the header and	"-rogzGB1v--git" is the	trailing


       The header consists of two uppercase characters ('"NB"')	followed by
       three digits (with leading zeros) representing the distribution version
       and a single character used to (potentially) indicate stability:
       "S"table	or "U"nstable.	Any deviation from this	indicates a bad
       client.	Recent stable builds will be found on CPAN.


       The remainder of	the Peer ID is a hyphen	followed by 13 random
       characters in the following range:


       That is,	all uppercase and lowercase letters, decimal digits, as	well
       as the hyphen, period, underscore, and tilde (66	total).	 These are all
       characters allowed in a URL without being encoded (referred to as
       "Unreserved Characters" in rfc 3986).

   Version Numbers and Stability
       Distribution version numbers will be some value less than one (1) with
       the revision number in the three	significant decimal places.

       Recent stable builds will be found on CPAN.  Unstable builds will most
       likely be private builds	or temporary uploads to	CPAN where the package
       name matches "m[\d\.\d+_\d]".  See the PAUSE FAQ	section	entitled
       "Developer Releases" (<>).

	   This	would be the stable CPAN-ready release "v0.393".  The "--git"
	   signature does not imply an unstable	build.

	   Improper Peer ID; the sixth char is neither '"S"' nor '"U"' and <
	   is a	reserved character according to	rfc: 3986.

	   Completely legal Peer ID generated by unstable build	around "v65".
