1Rails: why is calling to_a on a string not valid in a rake task?
2require 'openssl'

4KEY = 'secretkey'

6  namespace :import do
7  task :users => :environment do
8      def decrypt_password(pw)
9
10          cipher = OpenSSL::Cipher::Cipher.new('bf-ecb')
11          cipher.decrypt
12          cipher.key = KEY.to_a.pack('H*')    <<--------- FAILS RIGHT HERE on to_a
13
14          data = data.to_a.pack('H*')
15          data = cipher.update(data)
16          data << cipher.final
17          unpad(data)
18
19      end
20   end
