Set this parameter to on before creating an encrypted table. If this parameter is set to off, new encrypted tables cannot be created. The created encrypted table is decrypted only when data is read and is not encrypted when the data is written.

Setting suggestion: If indexes of all encrypted tables need to be encrypted, enable this parameter. You do not need to manually set indexes to encrypted indexes.

If the encryption type of the encrypted column is specified as random encryption, the column type is BYTEAWITHOUTORDERCOL). The original data type is displayed when the encrypted table is printed by running the meta command. 4 bytes plus the actual binary string.
