Active record callback after_find doesnot exist

I have a class in which the data is encrypted and stored for all fields. Whenever the record is loaded from database, the data should be decrypted. If there was a after_find callback, we could have done the decryption in that, but after_find doesnot exist. So how can we implement after_find or is there any other callback which can be useful.

According to ActiveRecord::Callbacks after_find does exists.
