#obfuscatejs

Rails gem for backend string obfuscation. Obfuscate any string using the simple obfuscate view helper in Rails.

##Installation

To use Obfuscatejs in your project, simply add it to your Gemfile:

	gem 'obfuscatejs'

and add Obfuscatejs to your app/assets/javascripts/application.js:

	//= require obfuscatejs 

##Usage

To use in a view:

	<%= obfuscate 'hello world' %>

Obfuscatejs obfuscates strings using Hex encryption so webcrawlers are unable to recognize the text.

Obfuscatejs also makes special provisions for email addresses. Use the obfuscate_email helper to automatically generate a <a href='mailto:your_email'>your_email</a> in your view. Usage is as follows:

	<%= obfuscate_email '[email protected]' %>
	# Outputs <a href='mailto:[email protected]'>[email protected]</a>

You are also able to provide a custom message in lieu of the email being the link text:

	<%= obfuscate_email '[email protected]', 'email me' %>
	# Outputs <a href='mailto:[email protected]'>email me</a>

Obfuscatejs also has support for subject and body fields in an email link:

	<%= obfuscate_email '[email protected]', 'email me', 'my subject' %>
	# Outputs <a href="mailto:[email protected]?subject=my%20subject">email me</a>

	<%= obfuscate_email '[email protected]', 'email me', 'my subject', 'my body' %>
	# Outputs <a href="mailto:[email protected]?subject=my%20subject&body=my%20body">email me</a>

	<%= obfuscate_email '[email protected]', 'email me', '', 'my body' %>
	# Outputs <a href="mailto:[email protected]?body=my%20body">email me</a>

##How it works

Obfuscatejs translates your text to Hex in the backend, then puts a <span data-obfuscated='hex_encrypted_text'></span> in your view. Obfuscatejs then runs a frontend script to translate that encrypted text to readable text only visible by human clients, and not spam bots.
