Oracle 11g encryption data test

Hi

1.I created a tablespace with encryption.

2. Created new table 'A' in the encrypted tablespace.

 3. Add values to the new table 'A'.

4. Alter system flush buffer cache;

5. Used Toad, to Query the values from table 'A'.

I see the data in regular form (not encrypted).

What is the use of having tablespace encryption, when someone can view the data in encrypted tables same as a regular tablespace?

My understanding is that any object belonging to encrypted tablespace, will have the data in encrypted form, so it is not visible to every user.

Please advice.

Thanks
