Ability to Set the Default Tablespace Encryption Algorithm

Security → Encryption

You now can set the TABLESPACE_ENCRYPTION_DEFAULT_ALGORITHM dynamic parameter to define the default encryption algorithm for tablespace creation operations. For example, if you set TABLESPACE_ENCRYPTION_DEFAULT_ALGORITHM to AES256, then future tablespace creation operations will use AES256 as the default encryption algorithm. TABLESPACE_ENCRYPTION_DEFAULT_ALGORITHM applies to both offline and online tablespace encryption operations. In addition, when you create a new database using Database Configuration Assistant (DBCA), you can set the default tablespace encryption algorithm by using the DBCA command line for silent installations.

Business Benefit: Supported encryption algorithms are AES128, AES192, AES256, 3DES168, ARIA128, ARIA192, ARIA256, SEED128, and GOST256. If you do not set TABLESPACE_ENCRYPTION_DEFAULT_ALGORITHM, then the default encryption algorithm is the default that was used in previous releases: AES128.
