attr_encryption

= attr_encryption

This gem enhances ActiveRecord models with the ability to quickly and easily define which attributes of the model are to be encrypted. Once the attributes have been identified, the gem takes care of all the details.

For example, if you want to encrypt the card number of a CreditCard model, you would simply code the following:

class CreditCard < ActiveRecord::Base attr_encrypted :card_number end

All that is required at this point is a column on the 'credit_cards' table named 'card_number_enc'.

There are a variety of options that can be applied to the attr_encrypted call to customize how the encryption proceeds, but more on that later.

• Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
• Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
• Fork the project.
• Start a feature/bugfix branch.
• Commit and push until you are happy with your contribution.
• Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
• Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
