= have-code

Add clever little base36 codes for your DataMapper and ActiveRecord objects.

== Whoa seriously??

   # ActiveRecord
   class Mug < ActiveRecord::Base
     have_code 60466169, 12034710206, 81268112
   end

   initech = Mug.create :name=>'initech', :material=>'porcelain'
   code = initech.code
   initech == Mug.find_by_code code
   
   # DataMapper
   class Goblet
     include DataMapper::Resource
     property :id, Serial
     property :name, String
     property :material, String
     have_code 60466169, 12034710206, 81268112
   end
   kohg = Goblet.create :name=>'king of hyrule', :material=>'gold'
   code = kohg.code
   kohg == Goblet.find_by_code code

== What are those big numbers?

In order:

[modulus] specifies how many different plaintexts and ciphertexts
          are available.
[a_key] multiplied against the plaintext. <b>Must be coprime with
        the modulus.</b>
[b_key] added to the multiplied plaintext.  No restrictions, but
        it's modulus math, so making it larger than +modulus+ is
        useless.

Change them to whatever you want, write tests to make sure they work
as expected.

== How secure is it?

Affine ciphers are incredibly easy to break.  See the readme for the
+affine+ gem or http://en.wikipedia.org/wiki/Affine_cipher for more.
