NAME

Digest::MD5::Reverse - MD5 Reverse Lookup

SYNOPSIS

 # Functional style
 use Digest::MD5::Reverse qw(r_md5 r_md5_hex r_md5_base64);

 $data = r_md5 $hash;
 $data = r_md5_hex $hash;
 $data = r_md5_base64 $hash;

 # OO style
 use Digest::MD5::Reverse;

 $ctx = Digest::MD5::Reverse->new;

 $ctx->add($hash);
 $data = $ctx->reverse;

DESCRIPTION

MD5 sums (see RFC 1321 - The MD5 Message-Digest Algorithm) are used as a one-way hash of data. Due to the nature of the formula used, it is impossible to reverse it.

This module provides functions to search several online MD5 hashes database and return the results (or return undefined if no match found).

We are not breaking security. We are however making it easier to lookup the source of a MD5 sum.

EXAMPLES

The simplest way to use this library is to import the r_md5_hex() function (or one of its cousins):

    use Digest::MD5::Reverse qw(r_md5_hex);

    print 'Data is ' r_md5_hex('6df23dc03f9b54cc38a0fc1483df6e21') "\n";

The above example would print out the message

    Data is foobarbaz

In OO style:

    use Digest::MD5::Reverse;

    $reverse = Digest::MD5::Reverse->new;
    $reverse->add('6df23dc03f9b54cc38a0fc1483df6e21');
    $data = $reverse->hexreverse;

    print "Data is $data\n";

You also can make a copy with clone:

        $reverse->clone->hexreverse

LIMITATIONS

It is very slow, because it will search each library until match found or all library search finished.
