Support for Oracle Database Encryption at Rest
Linking back to this post which appears unresolved: Does anyone know if Windchill supports Data encryption AT REST and IN TRANSIT within ORACLE or between ORACLE and the Application Server
My DBA pinged me on this recently. I see in docs that Oracle Transparent Data Encryption (TDE) tablespace encryption is documented and supported along with JDBC over SSL. From what I am told, TDE is not supported with Oracle Standard Edition. They are asked about Table Level Column Encryption called DBMS_CRYPTO. Reply back if you have anymore information.
