構筑TDE 環境的例子：

測試環境：12.1.0.2

$ cd $ORACLE_HOME/network/admin
$ vim sqlnet.ora

$ pwd
/u01/app/oracle/product/12.1.0/dbhome_1/network/admin

sqlnet.ora 需要配置：

$ cat sqlnet.ora

ENCRYPTION_WALLET_LOCATION =
?(SOURCE =(METHOD = FILE)(METHOD_DATA =
?? (DIRECTORY = /u01/app/oracle/admin/$ORACLE_SID/encryption_keystore/)


創建相應的目錄：

$ mkdir -p /u01/app/oracle/admin/$ORACLE_SID/encryption_keystore


創建 KEYSTORE:

$ sqlplus / as sysdba

SQL> ADMINISTER KEY MANAGEMENT CREATE KEYSTORE '/u01/app/oracle/admin/ora12102/encryption_keystore/' IDENTIFIED BY myPassword;


SQL> HOST ls /u01/app/oracle/admin/ora12102/encryption_keystore/
ewallet.p12 <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<??? 發現生成了相關的文件


SQL> ADMINISTER KEY MANAGEMENT SET KEYSTORE OPEN IDENTIFIED BY myPassword CONTAINER=ALL;

SQL> ADMINISTER KEY MANAGEMENT SET KEY IDENTIFIED BY myPassword WITH BACKUP CONTAINER=ALL;

確認結果：

SQL> SET LINESIZE 100
SQL> SELECT con_id, key_id FROM v$encryption_keys;

?? CON_ID

SQL> SET LINESIZE 200
SQL> COLUMN wrl_parameter FORMAT A50
SQL> SELECT * FROM v$encryption_wallet;

???????????????????????????????????????????????????????????? /

SQL> CONN sys@mypdb1 AS SYSDBA

SQL> SELECT con_id, key_id FROM v$encryption_keys;

?? CON_ID

KEY_ID
------------------------------------------------------------------------------------------------------------------------------------------------------------

SQL> grant dba to test identified by test;

SQL> conn test/test@mypdb1

SQL> CREATE TABLE tde_test (
?id??? NUMBER(10),
?data? VARCHAR2(50) ENCRYPT
); ?

SQL> INSERT INTO tde_test VALUES (1, 'This is a secret!');
SQL> commit;

SQL> conn sys@mypdb1 AS SYSDBA


創建 TDE 表領域：

SQL> CREATE TABLESPACE encrypted_ts
??????? DATAFILE '/home/oracle/tbs01.dbf' SIZE 128K
??????? AUTOEXTEND ON NEXT 64K
??????? ENCRYPTION USING 'AES256'
??????? DEFAULT STORAGE(ENCRYPT);

SQL> ALTER USER test QUOTA UNLIMITED ON encrypted_ts;

然后，可以使用TDE 表領域來創建和使用表了：

SQL> CONN test/test@mypdb1

SQL> CREATE TABLE tde_ts_test (
?id??? NUMBER(10),
?data? VARCHAR2(50)
) TABLESPACE encrypted_ts;


SQL> INSERT INTO tde_ts_test VALUES (1, 'This is also a secret!');
SQL> commit;
