Active Crypto

Encryption and decryption of a model's properties (Rails 4.1+, OpenSSL)

NOTE: Default key will be used from the secrets.yml file

Installation

Add this line to your application's Gemfile:

gem 'activecrypto'

And then execute:

$ bundle

Next, you need to run the generator:

$ rails g crypto:install

# app/models/user.rb
class User < ActiveRecord::Base
  # basic encrypt (default AES-256-CBC)
  encrypt :column_name
  ...
end

Or with with custom cipher like AES-256-CBC

class User < ActiveRecord::Base
  encrypt :column_name, { cipher: 'AES', block_mode: 'CBC', keylength: 256 }
  ...
end

If you need to choose an encryption algorithm. You can see the full list with:

ruby -r openssl -e 'puts OpenSSL::Cipher.ciphers'
