Data encryption and decryption in Oracle can be achieved by using the Oracle Advanced Security Option. Here is a simple example:

  1. Create an encrypted tablespace.
CREATE TABLESPACE encrypted_data
ENCRYPTION ALGORITHM 'AES128'
ENCRYPTED DEFAULT STORAGE;
  1. Create an encrypted table in the tablespace.
CREATE TABLE encrypted_table (
  id NUMBER,
  data VARCHAR2(50)
) TABLESPACE encrypted_data;
  1. Insert some encrypted data.
INSERT INTO encrypted_table VALUES (1, DBMS_CRYPTO.ENCRYPT('Hello', 2));
  1. Retrieve encrypted data.
SELECT id, DBMS_CRYPTO.DECRYPT(data, 2) FROM encrypted_table;

This example demonstrates how to use the DBMS_CRYPTO function for data encryption and decryption in Oracle. Please note that you need to install the Oracle Advanced Security Option in the database to use these features.
