Encryptor

Encrypt sensitive data on your ActiveRecord models or plain ol' Ruby objects using AES.

Installation

Add this line to your application's Gemfile:

gem 'encryptor'

And then execute:

$ bundle

Or install it yourself as:

$ gem install encryptor

Usage

Add this line within the class definition to any object, ActiveRecord model or not, you want to encrypt sensitive data:

$ include Encryptor

For any attribute you want to encrypt, add the line:

$ encrypted :attribute_name

This assumes you have two other attributes named encrypted_#{attribute_name} and #{attribute_name}_key.

It will then create #{attribute_name} and #{attribute_name}= methods that will transparently decrypt and encrypt the attribute.

Optionally, you can have two arguments that override the default name of the encrypted attribute and attribute key, like so:

$ encrypted :attribute_name, :optional_encrypted_attribute_name, :optional_attribute_key

TODO

• Tests, tests, tests
• Refactor out usage of AES into a strategy
