The ENCRYPTION_ALGORITHM parameter specifies the encryption algorithm to be used during the export, with the default being “AES128”. The syntax is shown below.
ENCRYPTION_ALGORITHM = { AES128 | AES192 | AES256 }
The ENCRYPTION_ALGORITHM parameter must be used in conjunction with the ENCRYPTION or ENCRYPTION_PASSWORD parameters,
