设置TABLESPACE_ENCRYPTION_DEFAULT_ALGORITHM 为 AES256, 接下来创建的表空间将使用 AES256 作为缺省的加密算法。 TABLESPACE_ENCRYPTION_DEFAULT_ALGORITHM 对 online 和 offline 表空间都可以执行; 如果使用 DBCA 创建,可以通过 SILENT 方式在命令行设置缺省加密算法;支持加密算法有 AES128, AES192, AES256, 3DES168;...
Oracle encrypts the data in the tablespace upon writing it and decrypts it upon reading the data. There is no additional memory requirement because the tablespace encryption and decryption aren’t performed in memory, the data has been decrypted before going to memroy, but there is an encryptio...
