RedactedAttributes

Stores redacted plain text version of an encrypted value

If you find yourself encrypting a value that you need to sort by, then this gem might help. It stores a redacted version of the string, the first three characters, in another column.

This gem is intended to be used with the symmetric-encryption gem. It assumes that a redacted_attribute column exists for the encrypted attribute.

Example

Let's assume we have the following ActiveRecord model defined.

class Widget < ActiveRecord::Base
  attr_encrypted :name
  attr_redacted  :name
end

This would require the database schema to look something like this.

  create_table "patients", :force => true do |t|
    t.string "encrypted_name"
    t.string "redacted_name"
  end

Installation

Add this line to your application's Gemfile:

gem 'redacted_attributes'

And then execute:

$ bundle

Or install it yourself as:

$ gem install redacted_attributes
