Easy Encryption provides a simple means for encrypting and decrypting strings. Uses the Gibberish gem (https://github.com/mdp/gibberish) under the hood to do the actual encryption work.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install easy_encryption
Finally, call setup on EasyEncryption passing your cipher key:
In a Rails app you will need to set the default cipher key inside of your app's ::Application.configure block:
config.after_initialize do EasyEncryption.setup 'secret' end
To enable the gem for your Rails tests, set the default cipher key inside of
test_helper.rb as in the first example.
EasyEncryption provides two additional methods that can be called on any string.
encrypt will encrypt a string:
encrypted_data = 'foo'.encrypt
decrypt will decrypt an encrypted string:
decrypted_data = encrypted_data.decrypt
For special cases where a different cipher key needs to be used, it can be passed directly:
encrypted_data = 'foo'.encrypt 'secret' decrypted_data = 'encrypted data'.decrypt 'secret'
string = 'foo' string.cipher_key = 'secret' encrypted_data = string.encrypt encrypted_data.cipher_key = 'secret' decrypted_data = encrypted_data.decrypt
