Answer to Question 1

An encryption key is a scrambling algorithm used to make data unreadable to anyone who does not have a decryption key (the algorithm that reverts the encrypted information back to its original state).

Answer to Question 2

The delete set-to-default option allows a record to be deleted if its primary key value is referred to by a foreign key value of a record in another relation. As a result, in all of the records where the foreign key value refers to the primary key of the record that is being deleted, the value of the foreign key is set to a predetermined default value.
