The TDE_CONFIGURATION parameter specifies the type of keystore (software keystore, hardware keystore, or Oracle Key Vault keystore). (Typically, this directory is called wallet.) Before you set WALLET_ROOT, ensure that you have an existing directory that you can use to store keystores. The WALLET_ROOT parameter specifies the keystore directory location. You can query a set of dynamic and data dictionary views to find more information about Transparent Data Encryption (TDE) data.īefore you can configure keystores and begin to encrypt data, you must perform a one-time configuration using the WALLET_ROOT and TDE_CONFIGURATION parameters to designate the location and type of keystores that you plan to create.
Transparent Data Encryption Data Dynamic and Data Dictionary Views.You can perform encryption operations on both offline and online tablespaces and databases. Encryption Conversions for Tablespaces and Databases.You can use Transparent Data Encryption to encrypt individual columns in database tables.

The search order for the TDE keystore depends on how you have set either the instance initialization parameters, the sqlnet.ora parameters, or the environment variables.Ī software keystore is a container for the master encryption key, and it resides in the software file system.Ī hardware keystore resides in a hardware security module (HSM), which is designed to store encryption keys.
