标题:给你的dmp文件(datapump)加上密码锁

作者:惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]

从oracle 11.1.0.7开始oracle 支持data pump导出加密,从而实现dmp文件安全.不会因为dmp文件丢失而导致数据泄露.涉及数据泵加密参数主要有:ENCRYPTION,ENCRYPTION_ALGORITHM,ENCRYPTION_MODE,ENCRYPTION_PASSWORD几个参数.这里测试的是使用最简单方式实现datapump加密功能,如果需要更好的数据安全可以考虑实时密码钱包

ENCRYPTION
Encrypt part or all of a dump file.
Valid keyword values are: ALL, DATA_ONLY, ENCRYPTED_COLUMNS_ONLY, METADATA_ONLY and NONE.
ENCRYPTION为加密dmp文件加密部分,其参数值可以有ALL, DATA_ONLY, ENCRYPTED_COLUMNS_ONLY, METADATA_ONLY and NONE,
如果只有ENCRYPTION_PASSWORD指定值,那么ENCRYPTION默认值为ALL
如果ENCRYPTION_PASSWORD和ENCRYPTION均为指定,那么默认值为NONE

ENCRYPTION_ALGORITHM
Specify how encryption should be done.
Valid keyword values are: [AES128], AES192 and AES256.
ENCRYPTION_ALGORITHM是指加密算法,参数值可以有AES128, AES192 and AES256。默认值为AES128

ENCRYPTION_MODE
Method of generating encryption key.
Valid keyword values are: DUAL, PASSWORD and [TRANSPARENT].
ENCRYPTION_MODE指定加密方式,其参数值有DUAL, PASSWORD and TRANSPARENT。默认值为TRANSPARENT
DUAL表示你指定的加密的dmp文件在导入的时候可以通过密码方式或者加密钱包方式导入
PASSWORD表示指定密码方式创建dmp文件,你导入也需要提供密码
TRANSPARENT需要加密钱包方式导出和导入

ENCRYPTION_PASSWORD
Password key for creating encrypted data within a dump file.
ENCRYPTION_PASSWORD指定加密密码
