To decrypt our text, we will require the secret key previously established in API secrets, the iv value, and, of course, the encrypted text. Decrypting data Let’s see now how our decryption function looks like then: Copy code snippet ...
whenever users access that data, Oracle decrypts the data and show it to the users. This encryption and decryption is completely transparent to the users. They never know that data was encrypted. The whole point behind transparent encryption is to keep the sensitive data in the data files ...
