active_record_string_encryption

ActiveRecordStringEncryption

Generates encrypt_string type that transparently encrypt and decrypt string value to ActiveRecord.

Support ActiveRecord 5.0 and later.

Installation

Add this line to your application's Gemfile:

gem 'active_record_string_encryption'

And then execute:

bundle install

Usage

Call ActiveRecord::Attribute API and specify :encrypt_string as type, then your database has encrypted value and application can get plain value.

class User < ActiveRecord::Base
  attribute :name, :encrypt_string
end

Must configure secret_key and salt for encryption and decryption. You can also configure algorithm, pass the value to cipher_alg. cipher_alg has default value aes-256-gcm so you do not need to configure if you want to use aes-256-gcm.

# config/initializers/active_record_string_encryption.rb
ActiveRecordStringEncryption.configure do |c|
  c.secret_key = ENV['ENCRYPTION_SECRET_KEY'],
  c.salt = ENV['ENCRYPTION_SALT'],
  c.cipher_alg = 'aes-256-gcm'
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
