-MathCaptcha
-===========
-
-TODO: Create form helpers
-
-Validates your Model to be saved by a human (or very clever script) by asking
-the user to solve a very basic mathematical equation.
-
-It does not use the session to store the secret, but uses AES from EzCrypto.
-
-
-Requirements
-============
- * gem ezcrypto
- * users who can calculate
-
-Usage
-=====
-
-In your Model < ActiveRecord::Base
-
-      has_captcha
-
-
-In your form view:
-
-      <%= @model.captcha.task %> = ?
-      <%= form.text_field :captcha_solution %>
-      <%= form.hidden_field :captcha_secret %>
-
-
-If you want to skip the validation (in tests/specs), you can 
-
-      Model.skip_captcha!   # or
-      @model.skip_captcha!
-
-and turn that off by
-
-      Model.dont_skip_captcha!   # or
-      @model.dont_skip_captcha!
-

+= reCAPTCHA
+
+Author::    Jason L Perry (http://ambethia.com)
+Copyright:: Copyright (c) 2007 Jason L Perry
+License::   {MIT}[http://creativecommons.org/licenses/MIT/]
+Info::      http://ambethia.com/recaptcha
+Git::       http://github.com/ambethia/recaptcha/tree/master
+Bugs::      http://github.com/ambethia/recaptcha/issues
+
+This plugin adds helpers for the {reCAPTCHA API}[http://recaptcha.net]. In your
+views you can use the +recaptcha_tags+ method to embed the needed javascript,
+and you can validate in your controllers with +verify_recaptcha+.
+
+Beforehand you need to configure Recaptcha with your custom private and public
+key. You may find detailed examples below. Exceptions will be raised if you
+call these methods and the keys can't be found.
+
+== About this fork
+
+This fork tries to introduces a more convenient way to configure recaptcha's
+settings. The API will be inspired by {Thoughtbot's
+Hoptoad}[http://robots.thoughtbot.com/post/344833329/mygem-configure-block].
+
+== Rails Installation
+
+reCAPTCHA for Rails, add this to your Gemfile:
+
+  gem "recaptcha", :require => "recaptcha/rails"
+
+Or, it can be installed as a gem:
+
+  config.gem "recaptcha", :lib => "recaptcha/rails"
+
+Or, as a standard rails plugin:
+
+  script/plugin install git://github.com/ambethia/recaptcha.git
+
+== Merb Installation
+
+reCAPTCHA can also be used in a Merb application when installed as a gem:
+
+  dependency "alm-recaptcha", ">=0.2.2.1", :require_as => "recaptcha/merb"
+
+Initial Merb compatability funded by ALM Labs.
+
+== Setting up your API Keys
+
+There are multiple ways to setup your reCAPTCHA API key once you
+{obtain}[http://recaptcha.net/whyrecaptcha.html] a pair.
+
+=== Recaptcha.configure
+
+You may use the block style configuration. The following code could be placed
+into a +config/initializers/recaptcha.rb+ when used in a Rails project.
+
+  Recaptcha.configure do |config|
+    config.public_key  = '6Lc6BAAAAAAAAChqRbQZcn_yyyyyyyyyyyyyyyyy'
+    config.private_key = '6Lc6BAAAAAAAAKN3DRm6VA_xxxxxxxxxxxxxxxxx'
+    config.proxy = 'http://myrpoxy.com.au:8080'
+  end
+
+This way, you may also set additional options to fit recaptcha into your
+deployment environment.
+
+== Recaptcha#with_configuration
+
+If you want to temporarily overwrite the configuration you set with `Recaptcha.configure` (when testing, for example), you can use a `Recaptcha#with_configuration` block:
+
+  Recaptcha.configure(:public_key => '12345') do
+    # Do stuff with the overwritten public_key.
+  end
+
+=== Shell environment
+
+Or, you can keep your keys out of your code base by exporting the following
+environment variables. You might do this in the .profile/rc, or equivalent for
+the user running your application:
+
+  export RECAPTCHA_PUBLIC_KEY  = '6Lc6BAAAAAAAAChqRbQZcn_yyyyyyyyyyyyyyyyy'
+  export RECAPTCHA_PRIVATE_KEY = '6Lc6BAAAAAAAAKN3DRm6VA_xxxxxxxxxxxxxxxxx'
+
+=== Per call
+
+You can also pass in your keys as options at runtime, for example:
+
+  recaptcha_tags :public_key => '6Lc6BAAAAAAAAChqRbQZcn_yyyyyyyyyyyyyyyyy'
+
+and later,
+
+  verify_recaptcha :private_key => '6Lc6BAAAAAAAAKN3DRm6VA_xxxxxxxxxxxxxxxxx'
+
+This option might be useful, if the same code base is used for multiple
+reCAPTCHA setups.
+
+== To use 'recaptcha'
+
+Add +recaptcha_tags+ to each form you want to protect.
+
+And, add +verify_recaptcha+ logic to each form action that you've protected.
+
+=== +recaptcha_tags+
+
+Some of the options available:
+
+<tt>:ssl</tt>::         Uses secure http for captcha widget (default +false+)
+<tt>:noscript</tt>::    Include <noscript> content (default +true+)
+<tt>:display</tt>::     Takes a hash containing the +theme+ and +tabindex+ options per the API. (default +nil+)
+<tt>:ajax</tt>::        Render the dynamic AJAX captcha per the API. (default +false+)
+<tt>:public_key</tt>::  Your public API key, takes precedence over the ENV variable (default +nil+)
+<tt>:error</tt>::       Override the error code returned from the reCAPTCHA API (default +nil+)
+
+You can also override the html attributes for the sizes of the generated +textarea+ and +iframe+
+elements, if CSS isn't your thing. Inspect the source of +recaptcha_tags+ to see these options.
+
+=== +verify_recaptcha+
+
+This method returns +true+ or +false+ after processing the parameters from the reCAPTCHA widget. Why
+isn't this a model validation? Because that violates MVC. You can use it like this, or how ever you
+like. Passing in the ActiveRecord object is optional, if you do--and the captcha fails to verify--an
+error will be added to the object for you to use.
+
+Some of the options available:
+
+<tt>:model</tt>::       Model to set errors
+<tt>:attribute</tt>::   Model attribute to receive errors (default :base)
+<tt>:message</tt>::     Custom error message
+<tt>:private_key</tt>:: Your private API key, takes precedence over the ENV variable (default +nil+).
+<tt>:timeout</tt>::     The number of seconds to wait for reCAPTCHA servers before give up. (default +3+)
+
+  respond_to do |format|
+    if verify_recaptcha(:model => @post, :message => "Oh! It's error with reCAPTCHA!") && @post.save
+      # ...
+    else
+      # ...
+    end
+  end
+
+== I18n support
+reCAPTCHA passes two types of error explanation to a linked model. It will use the I18n gem
+to translate the default error message if I18n is available. To customize the messages to your locale,
+add these keys to your I18n backend:
+
+<tt>recaptcha.errors.verification_failed</tt>:: error message displayed if the captcha words didn't match
+<tt>recaptcha.errors.recaptcha_unavailable</tt>:: displayed if a timout error occured while attempting to verify the captcha
+
+== TODO
+* Remove Rails/ActionController dependencies
+* Framework agnostic
+* Add some helpers to use in before_filter and what not
+* Better documentation
