Part I describes how to use Transparent Data Encryption.

• Introduction to Transparent Data Encryption
  Transparent Data Encryption enables you to encrypt sensitive data, such as credit card numbers or Social Security numbers.
• Configuring United Mode
  United mode enables you to create a common keystore for the CDB and the PDBs for which the keystore is in united mode.
• Configuring Isolated Mode
  Isolated mode enables you to create a keystore for each pluggable database (PDB).
• Encrypting Columns in Tables
  You can use Transparent Data Encryption to encrypt individual columns in database tables.
• Encryption Conversions for Tablespaces and Databases
  You can perform encryption operations on both offline and online tablespaces and databases.
• Managing the Keystore and the Master Encryption Key
  You can modify settings for the keystore and TDE master encryption key, and store Oracle Database and store Oracle GoldenGate secrets in a keystore.
• Administering United Mode
  Administering united mode means managing the keystores, master encryption keys, and general Transparent Database Encryption (TDE) functionality.
• Administering Isolated Mode
  Administering isolated mode means managing the keystores, master encryption keys, and general Transparent Database Encryption (TDE) functionality.
• General Considerations of Using Transparent Data Encryption
  When you use Transparent Data Encryption, you should consider factors such as security, performance, and storage overheads.
• Using Transparent Data Encryption with Other Oracle Features
  You can use Oracle Data Encryption with other Oracle features, such as Oracle Data Guard or Oracle Real Application Clusters.
• Using sqlnet.ora to Configure Transparent Data Encryption Keystores
  If you do not want to use the WALLET_ROOT and TDE_CONFIGURATION parameters to configure the keystore location, then you can use the sqlnet.ora file.
