How to parse encrypted data in oracle?

To parse encrypted data in Oracle, you will need to decrypt the data using the encryption key or algorithm that was used to encrypt it. Here are the steps to decrypt encrypted data in Oracle:

1. Identify the encryption algorithm or key that was used to encrypt the data. This information is crucial for decrypting the data.
2. Use the appropriate decryption function in Oracle to decrypt the data. Oracle provides several encryption functions such as DBMS_CRYPTO for decrypting data.
3. Write a query in Oracle SQL to select and decrypt the encrypted data. For example, if the encrypted data is stored in a column called 'encrypted_data' in a table called 'my_table', you can write a query like:

1
2

SELECT DBMS_CRYPTO.DECRYPT(UTL_RAW.CAST_TO_RAW(encrypted_data), 2, 'AES128') as decrypted_data 
FROM my_table;

In this query, 'UTL_RAW.CAST_TO_RAW' function is used to convert the encrypted data into a RAW format, '2' is the decryption algorithm (AES128 in this case), and 'AES128' is the key used for decryption.

1. Execute the query in Oracle SQL Developer or any other SQL client to decrypt the encrypted data.
2. Make sure to handle and store the decrypted data securely to prevent unauthorized access.

By following these steps, you can successfully parse and decrypt encrypted data in Oracle.
