Column encryption - creating new table that has encrypted column(s)

In this recipe, you're going to learn to use TDE column encryption to encrypt columns in a newly created table.

Getting ready

It is assumed that a keystore is opened and a master key is created.

How to do it...

  1. Connect to the database as a user who has administer key privilege or SYSKM privilege (for example, maja):

    $ sqlplus maja

  2. Create a new table (for example, table enc_cols in schema hr) that has, for example, the following structure:

    Column name

    Column type

    Encrypted

    NAME

    VARCHAR2 (50)

    No

    CREDIT_LIMIT

    NUMBER (10)

    Yes, AES192

    SALARY

    NUMBER (10)

    Yes, AES192

    Figure 11 - A syntax to create the table hr.enc_cols

  3. Connect to the database as a user who can insert and view data in the table (for example, hr user):

    SQL> connect hr

  4. Insert several arbitrary values into the table HR.ENC_COLS.

    Figure 12 - Test values

  5. Verify that the user can view unencrypted values in all columns.

    Figure 13- Encryption is transparent

  6. Connect...
