NAME

       Bencode - BitTorrent serialisation format

VERSION

       version 1.4

SYNOPSIS

        use Bencode qw( bencode bdecode );

        my $bencoded = bencode { 'age' => 25, 'eyes' => 'blue' };
        print $bencoded, "\n";
        my $decoded = bdecode $bencoded;

DESCRIPTION

       This module implements the BitTorrent bencode serialisation format as described in
       <http://www.bittorrent.org/protocol.html>.

INTERFACE

   "bencode( $datastructure )"
       Takes a single argument which may be a scalar or a reference to a scalar, array or hash.
       Arrays and hashes may in turn contain values of these same types. Simple scalars that look
       like canonically represented integers will be serialised as such. To bypass the heuristic
       and force serialisation as a string, use a reference to a scalar.

       Croaks on unhandled data types.

   "bdecode( $string [, $do_lenient_decode [, $max_depth ] ] )"
       Takes a string and returns the corresponding deserialised data structure.

       If you pass a true value for the second option, it will disregard the sort order of dict
       keys. This violation of the bencode format is somewhat common.

       If you pass an integer for the third option, it will croak when attempting to parse
       dictionaries nested deeper than this level, to prevent DoS attacks using maliciously
       crafted input.

       Croaks on malformed data.

DIAGNOSTICS

       "trailing garbage at %s"
           Your data does not end after the first bencode-serialised item.

           You may also get this error if a malformed item follows.

       "garbage at %s"
           Your data is malformed.

       "unexpected end of data at %s"
           Your data is truncated.

       "unexpected end of string data starting at %s"
           Your data includes a string declared to be longer than the available data.

       "malformed string length at %s"
           Your data contained a string with negative length or a length with leading zeroes.

       "malformed integer data at %s"
           Your data contained something that was supposed to be an integer but didn't make
           sense.

       "dict key not in sort order at %s"
           Your data violates the bencode format constaint that dict keys must appear in lexical
           sort order.

       "duplicate dict key at %s"
           Your data violates the bencode format constaint that all dict keys must be unique.

       "dict key is not a string at %s"
           Your data violates the bencode format constaint that all dict keys be strings.

       "dict key is missing value at %s"
           Your data contains a dictionary with an odd number of elements.

       "nesting depth exceeded at %s"
           Your data contains dicts or lists that are nested deeper than the $max_depth passed to
           "bdecode()".

       "unhandled data type"
           You are trying to serialise a data structure that consists of data types other than

           •   scalars

           •   references to arrays

           •   references to hashes

           •   references to scalars

           The format does not support this.

BUGS AND LIMITATIONS

       Strings and numbers are practically indistinguishable in Perl, so "bencode()" has to
       resort to a heuristic to decide how to serialise a scalar. This cannot be fixed.
