Module: Serket::EncryptedFields

Defined in:
lib/serket/encrypted_fields.rb

Overview

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

For example:

class Person

extend Serket::EncryptedFields

encrypted_fields :name, :email

end

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

When a value is assigned to name or email for a given person instance, it will automatically generate an encrypted version using the currently configured public key, and will store the cipher text instead of the plaintext value that was assigned.

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