Table Encryption Question
Greeting All. I need to encrypt some PII columns in a few tables. What is the best/easiest way to do that? My understanding is TDE is not the choice because it does not prevent unauthorized people from accessing the data while give access to authorized people. DBMS_CRYPTO is intended to replace the DBMS_OBFUSCATION_TOOLKIT, but it does not even support VARCHAR2, the most commonly used data type. Thanks for your advice.
