-        PROCEDURE SET_KEY( I_KEY_NAME IN VARCHAR2 )
-            For inserting/updating there must be at least one current key to encrypt data. We can set it by this proceudre.

-            Returns with the encrypted form of the specified value. Both the value and encrypted forms are strings.

-            Returns with the decrypted form of the specified value. The function uses the specified key (name) for decrypting.
-            Returns with null if the key name does not exsist in the list of set up keys, or in case of any other invalid situation.
