Answer: Informix IDS supports the use of column-level encryption to store sensitive data in an encrypted format. After encrypting sensitive data, such as credit card numbers, only users who can provide a secret password can decrypt the data. The CDC API can read the column data from logical logs in encrypted format and consequently the Oracle GoldenGate Extract process will write the encrypted column data to the trail file. This ensures that security is not compromised.
