Rails encryption: danpal/attr_encryptor key generation

Question

Using the danpal fork of attr_encrypted.

attr_encrypted  :col_int, :key => 'key', :if => :encryption_required, :marshall => true

Does the 'key' string generate a new object with a new session? Since I have ran into a problem where I have created an instance with the encrypted value and it works fine. However when I run a new rails console session or for example try and access the value through a view I get a bad decrypt error. I am guessing it is related to having an incorrect key? As in the new session will pass a different string object as the key?

Is there anyway to avoid this?

Answer 1

Problem was in not reading the documentation, an extra col_int_salt and col_int__iv columns are required
