Setting Encryption Parameters

Set ciphertext encoding mode after encryption. The encoding mode can be hexadecimal or BASE64. If you want to support fuzzy search, the encryption parameter must be set to hexadecimal format.

Constraint

You can change the ciphertext encoding mode only when no asset is configured in the system.

Procedure

  1. Log in to a database encryption and access control instance as the sysadmin user.
  2. In the navigation tree on the left, choose Data Encryption > Encryption Parameter.
  3. On the Encryption Parameter page, you can select Hexadecimal or BASE64 from the Ciphertext Encoding Mode drop-down list box.
  4. The ciphertext of the encryption table is displayed as a hexadecimal or BASE64 string. For example, Figure 1.
