I'm trying to get a test to pass and keep getting a "no method error" I'm using the routines from Chapter 8 of "Security on Rails" and can't get the test to pass. I keep getting "no method error" for decrypt. Can someone help me with the correct "address" for decrypt so I can call it directly.
Here is the routine definition:
module Encryptor module Routines def decrypt(cipher_text, key, opts) cipher = OpenSSL::Cipher::Cipher.new(algorithm(opts)) decoded_cipher_text = Base64.decode64(cipher_text) #cipher.decrypt(key, decoded_cipher_text.slice!(0..15)) cipher.decrypt cipher.pkcs5_keyivgen(key) # DW 11/3/10 Above two lines per deprecation warning and stackoverflow site # TODO Use a real Salt instead of Thoracic1 out = cipher.update(decoded_cipher_text) out << cipher.final end end end
Here is the "after save" hook:
module Encryptor module ActiveRecord class Encryptor include ::Encryptor::Routines
def after_save(model) unless model[@field].blank? key = model.class.encryption_key model[@field] = decrypt(model[@field], key, @options) end end end end end
Here is the test:
require 'test_helper' class UserTest < ActiveSupport::TestCase
fixtures :users
test "the_encrypter" do @user = users(:bob) @user.secret_answer = "Volvo" assert @user.save @answer = User.connection.select_all( "select secret_answer from users where id = 1" ) cipher_text = @answer.first['secret_answer'] opts = Encryptor::ActiveRecord::Encryptor.default_options @plain_text = decrypt(cipher_text, User.encryption_key, opts) assert_equal @plain_text, "Volvo" end end
