How can I use encryption attributes in Rails?

In Rails, you can use the attr_encrypted gem to easily encrypt attributes in your models. Would you like a code example?

Yes, please provide a code example.

Sure! First, add attr_encrypted to your Gemfile:

gem 'attr_encrypted'

Then, in your model, you can do:

class User < ApplicationRecord
  attr_encrypted :email, key: 'a secret key'
end

What if I want to encrypt multiple attributes?

You can encrypt multiple attributes by listing them in the attr_encrypted method:

class User < ApplicationRecord
  attr_encrypted :email, key: 'a secret key'
  attr_encrypted :phone_number, key: 'another secret key'
end
