NAME

Convert::Bencode - Functions for converting to/from bencoded strings

SYNOPSIS

  use Convert::Bencode qw(bencode bdecode);
  my $string = "d4:ainti12345e3:key5:value4:type4:teste";
  my $hashref = bdecode($string);
  foreach my $key (keys(%{$hashref})) {
      print "Key: $key, Value: ${$hashref}{$key}\n";
  }
  my $encoded_string = bencode($hashref);
  print $encoded_string."\n";

DESCRIPTION

This module provides two functions, "bencode" and "bdecode", which encode and decode bencoded strings respectivly.

Encoding

bencode() expects to be passed a single value, which is either a scalar, a arrary ref, or a hash ref, and it returns a scalar containing the bencoded representation of the data structure it was passed. If the value passed was a scalar, it returns either a bencoded string, or a bencoded integer (floating points are not implemented, and would be returned as a string rather than a integer). If the value was a array ref, it returns a bencoded list, with all the values of that array also bencoded recursivly. If the value was a hash ref, it returns a bencoded dictionary (which for all intents and purposes can be thought of as a synonym for hash) containing the recursivly bencoded key and value pairs of the hash.

Decoding

bdecode() expects to be passed a single scalar containing the bencoded string to be decoded. Its return value will be either a hash ref, a array ref, or a scalar, depending on whether the outer most element of the bencoded string was a dictionary, list, or a string/integer respectivly.

BUGS

No error detection of bencoded data. Damaged input will most likely cause very bad things to happen, up to and including causeing the bdecode function to recurse infintly.
