Module: Serket::DecryptedFields

Defined in:
lib/serket/decrypted_fields.rb

Overview

If a class extends DecryptedFields, then the getter method will be overridden for each attribute that is listed.

For example:

class Person

extend Serket::DecryptedFields

decrypted_fields :name, :email

end

This will create a method name=(value) and email=(value)

It assumes the encrypted name and email will be assigned to an instance of person, and will automatically decrypt the encrypted value using the configured private key.

This currently relies on the write_attribute, which is available in ActiveRecord::Base. This currently is only intended for use with rails.
